William J. Miller -- Chief Executive Officer

Thank you, Anthony. Good afternoon, everyone, and thank you for joining the call. I hope you and your families are well. I'm excited to talk to you today about the strong progress we've made on our transformation. Our team executed through the quarter, operating remarkably well through this global pandemic.

To begin, I will take you through our highlights. John will provide a financial update and guidance, and then I will discuss our markets and technologies before taking your questions. Reflecting on 2020, I'm proud of what our Veeco united team has accomplished. We completed our organizational restructuring and began to reshape our product portfolio. We improved gross margins, reduced operating expenses and improved profitability. We restructured our debt and strengthened our balance sheet. We also enhanced our governance, appointing an independent chair to the Board of Directors and assigning our second recently appointed female Board Member to the Audit Committee. We improved our focus on ESG and published our first sustainability report. And importantly, we continue to focus on our employees and internal culture. Together, these actions, along with investments in R&D and service to support multiple evaluation systems are positioning Veeco for our next phase of growth and value creation in semiconductor and compound semiconductor markets.

Looking at our full year highlights. 2020 was a remarkable year of improvement for Veeco. Revenue for the full year was $454 million, compared to $419 million in 2019. Our gross margin improved by nearly five percentage points to 43% in 2020, as a result of our reorganization and expense management, we reduced operating expenses to $144 million in 2020 from $156 million in 2019. From an overall profitability perspective, we achieved $52 million in non-GAAP operating income and reversed our diluted non-GAAP EPS from a loss of $0.03 in 2019 to a profit of $0.86 in 2020. These results drove $43 million in cash flow from operations. Once again, the Veeco united team did an amazing job focusing on success and executing in a challenging environment.

Now for a look at our Q4 2020 highlights, Q4 mark another solid quarter of execution driven by strength in our semiconductor and compound semiconductor markets. Revenue came in at $130 million, which was above the high end of our guidance and diluted non-GAAP EPS came in at $0.30, which was at the midpoint of our guidance. Our gross margin came in at 41% and we achieved non-GAAP operating income of $18 million. In addition, we generated $15 million in cash flow from operations and increased our cash and short-term investments by $10 million. John will provide more details on the financials in just a few minutes.

We're optimistic about our growth opportunities in 2021. Market drivers such as semiconductor, 5G and data center demand are all trending positively and are aligned with Veeco's near-term growth objectives in laser annealing, 5G RF and data storage applications. And our outlook for 2021 is supported by our backlog. As we look out beyond 2021, semiconductor demand is growing and as such, we evaluated options to increase production capacity for our laser annealing systems. After considering a range of alternatives, we decided investing in new facility offers the best solution. We are excited about the growth opportunity for our laser annealing product, and we'll be sharing more details on this in the near future.

On a related note, we are also proud to announce that we received a multi-system order for our laser annealing product from a leading semiconductor customer for a second application at an advanced logic node. This further validates the capability of our laser annealing technology and provides momentum as we enter at 2021.

And with that, I'll turn the call over to John for review of the financials.

John P. Kiernan -- Senior Vice President and Chief Financial Officer

Thanks, Bill, and good afternoon, everyone. Today, I will be discussing non-GAAP financial data. I would encourage you to refer to our reconciliation between GAAP and non-GAAP results, which you can find in our press release or at the end of the quarterly earnings presentation. Before turning to our revenue by market and geography, I would like to remind everyone that we modified the way we report revenue by end-market to align with the company's evolving strategy.

Today, we are providing revenue in our new end markets. In the back half section of the earnings presentation, you can find historical data reclassify to the new end markets for comparative purposes. As shown on the slide, our new end markets are semiconductor, which includes frontend and backend semiconductor as well as EUV mask blank systems. Our second market is compound semiconductor, which includes RF filter and device application, power electronics, and Photonics applications such as pixels, laser diodes, and microLED display. Our third market is data storage, which includes equipment supporting thin-film magnetic head manufacturing. And our fourth market is scientific and other which includes research institutions and other applications.

Looking at full year revenue, our semiconductor revenue was $166 million, which represented 36% of the total and a decline of about 6% from the prior year. We expect this market to grow in 2021 on strength in laser annealing systems. Compound semiconductor revenue was $108 million, a 26% increase from 2019 and made up 24% of the total driven by Photonics and RF applications. Data storage revenue was $123 million, a 47% increase over the prior year and made up 27% of our total revenue as hard disk drive customers added capacity for thin film magnetic head manufacturing. And scientific and other revenue was $57 million, a decline of 23% from 2019 and made up 13% of the total revenue.

And looking at our full year revenue by region, please take note that we have modified our region naming convention. Our Asia Pacific region, excluding China made up 39% of total revenue. The United States was 32%. EMEA was 16%. China made up 13%. And finally, rest of the world made up less than 1% of our revenue for the year.

Turning to Q4 revenue by market and geography. Revenue totaled $139 million for the quarter, which was the sequential increase of 24% and a year-on-year increase of 23%. We had strong performance in our semiconductor market, which made up 41% of our revenue driven by multiple laser annealing systems and an EUV ion beam system shipment. The compound semiconductor market contributed 33% of our revenue and was driven by multiple system shipments for 5G RF applications and shipments to Photonic customers. Our revenue in this market also included the sale of commodity LED systems, which enabled us to monetize slow moving inventory.

Our data storage market came in at 14% of total revenue. We expect growth in 2021 in our data storage market, based upon our order backlog going into the year. And finally, the scientific and other market made up 12% of our revenue with systems shift for a variety of research applications. And looking at our quarterly revenue by region, our Asia Pacific region, excluding China made up 48% of total revenue. The United States was 26%. China made up 14%. EMEA was 12% and finally, rest of the world made up less than 1% of our revenue for the quarter.

And now turning to non-GAAP operating results. On full year 2020 basis, as Bill mentioned, we achieved gross margin of 43% and reduced our annual operating expenses to $144 million. These improvements reflect the impact of our transformation effort. Our non-GAAP operating income increased significantly from $5 million in 2019 to $52 million in 2020. This drove diluted EPS of $0.86 for the year.

And now I'll provide a few additional full year figures. For fiscal 2020, non-GAAP depreciation was $15.1 million. Amortization was $15.3 million. And our equity comp expense was $12.7 million. Cash interest on our debt was $10.8 million and cash taxes were $300,000. At year end, we had federal NOL for $293 million, which are fully reserved. While we no longer provide bookings on a quarterly basis, we do provide backlog in our 10-K, when we file, you will see that as a result of a strong year of order intake, we ended 2020 with $366 million in backlog. The biggest contributor by market is data storage followed by semiconductor, compound semiconductor, and scientific and other in that order. A significant portion of the increased data storage backlog is anticipated to be delivered in the second and third quarters of 2021. We are proud of the progress we've made on our transformation execution and our 2020 financial results are a reflection of that hard work. We are now focused on investing to drive growth in 2021 and beyond.

Now turning to our quarterly results. Gross margin came in at 41%, which was lower than guidance. This was due to monetize and slow moving LED inventory as well as service costs related to both 5G installations and future semiconductor growth. Gross margins are influenced by a number of factors and we expect quarter-to-quarter variations. Operating expenses for the quarter were $40 million, and as a percentage of revenue declined sequentially from 32% in Q3 2020 to 29% in Q4 2020. We incurred higher variable expenses associated with the increase in revenue and order intake. Additionally, we strategically increased R&D expenses as planned in support of our growth initiatives.

On a non-GAAP basis, tax expense for the quarter was a benefit of approximately $300,000, with net income coming in at $15 million. And EPS was $0.30 on a diluted share count of 50 million shares. It's worth noting that our Q4 GAAP net loss for the $100,000 includes a non-cash charge of $4.9 million, resulting from our convertible debt exchange completed in the quarter.

Now moving to the balance sheet and cash flow highlights. We ended the quarter with cash and short-term investments of $320 million, a sequential increase of $10 million. From a working capital perspective, our accounts receivable remain flat at $80 million on increased revenues. DSOs for the quarter came in at 52 days, an improvement from the prior quarter. Accounts payable also remain flat at $34 million. Inventory increased approximately $3 million to $146 million, resulting from investments we are making to ship evaluation systems in support of our growth strategy in semiconductor and compound semiconductor markets. Days of inventory came in at $159 million, an improvement from 200 days in the prior quarter. Long-term debt on the balance sheet was recorded at $321 million, representing the carrying value of $389 million in convertible notes. Our CapEx during the quarter was $3.5 million, bringing CapEx total for the year to $6.8 million.

Now turning to our convertible notes. As outlined on the slide, the actions we took over the course of 2020, we went from single $345 million tranche of debt due in January 2023 to a more manageable debt structure with three maturities, roughly evenly staggered over the next six years. Our annual cash interest expense is expected to be approximately $13 million on a go-forward basis. With this debt structure and strong balance sheet, we have the flexibility and capital to focus on driving long-term organic growth across our business.

Now turning to Q1 guidance. Q1 revenue is expected to be between $115 million and $135 million with non-GAAP gross margin between 40% and 42%. Gross margin estimate reflects our anticipated product mix as well as service costs related to both evaluation systems and customers RF -- 5G RF around. We expect non-GAAP OpEx to be between $37 million and $39 million, a reduction from Q4 principally in SG&A expenses. GAAP EPS is expected between a loss of $0.09 and earnings of $0.09 per diluted share.

Non-GAAP EPS is expected between $0.12 and $0.30 per diluted share diluted. Diluted non-GAAP EPS is based upon a 50 million share count at stock prices of about $20 per share. There in mind taking our convertible notes into account, the share count for the diluted EPS calculation will increase by about 300,000 shares on average per every dollar increase in the average stock price over the course of the quarter. We have included a table in the back half section of the earnings presentation to provide detail on the effect of the convertible notes on the diluted share count.

And now some additional color beyond Q1, based on our current visibility and backlog, we are increasing our revenue outlook for 2021 and now expect revenue for the full year to be in the $520 million to $540 million range. And we are targeting non-GAAP EPS for the full year to be between $1 and $1.20.

I'd like to provide a little bit more information on the capacity expansion plans that Bill mentioned earlier. We are currently in the final stages of lease negotiations for San Jose property of approximately the same size of our current facility, but with a better footprint, allowing us to increase the size and efficiency of our production space. Capital expenditures associated with this project are expected to be between $30 million and $40 million over the next two years. Additionally, there'll be a period of duplicate expenses until the transition to the new facility is completed.

And with that, I'll turn it back over to Bill for market update.

William J. Miller -- Chief Executive Officer

Turning to the markets we serve and our technologies. With the first phase of our transformation behind is, we will continue to focus on the second phase of our transformation growing the company organically and the semiconductor and compound semiconductor markets. We think of this growth in two phases, near-term 2021 growth and longer term 2022 and beyond. Our near-term growth outlook is supported by recent semiconductor orders for advanced-node logic customers, demand for 5G RF related capacity and market demand and backlog in data storage.

Looking beyond 2021, we've been investing in our core technologies, which will drive the next phase of Veeco's growth that enable game changing applications like artificial intelligence, virtual and augmented reality in electric vehicles. We are well positioned to continue to play a meaningful role with our customers and we are making the necessary investments in R&D, service and evaluation systems to deliver and support products they need. In fact, evaluation agreements are already in place for our laser annealing systems for logic and memory applications and our MOCVD systems for early stage microLED development.

Now looking more specifically at each of our four markets. In our semiconductor market, we won an additional laser annealing step at one of our existing customers advanced nodes. In addition to that, we see multiple growth vectors, we believe will drive growth in laser annealing. We continue to make progress with our customers on their next nodes. In fact, we expect to ship evaluation systems to multiple customers in the coming quarters. We are making progress with a third logic customer at an advanced node. And lastly, while our LSA product line has historically been applied for logic applications, a top tier memory customer is currently evaluating Veeco's laser annealing solutions. This is a one-year evaluation and could result in a significant new market opportunity, which could produce revenue growth in '22 and beyond.

In summary, our laser annealing technology, with its unique process capabilities in advanced nodes is providing near-term strength and is also an important component of our longer term growth strategy. In the EUV mask blank market, we shipped the system in the quarter and we continue to work closely with our customers on future plans for capacity expansion as the industry progresses. ASML recently announced they shipped 31 EUV lithography systems in 2020, up from 26 in 2019, and they entered 2021 with 42 systems in backlog, with roughly one of our mask blank systems required for every 10 to 15 ASML systems in the field. We continue to see our market opportunity as two to four systems per year on average. In advanced packaging, we saw positive order activity during the quarter for our of lithography and wet processing systems, for applications such as flipped chip and fan-out wafer level packaging. And we continue to engage with our customers to solve their next generation advanced packaging challenges.

Moving to compound semiconductor, we serve this market primarily with our wet processing and MOCVD equipment. Our wet processing equipment offers excellent process control and flexibility for many compounds semiconductor applications. We shipped multiple systems during the quarter, and we are seeing further demand for RF customers as they add filter and power amplifier production capacity. Looking at our MOCVD business, we have pivoted away from the commodity LED market and toward providing high value solutions for our customers. We have strengthened our product portfolio, which we believe is now well-positioned to compete in exciting high growth markets. These include applications in Photonics such as indium phosphide lasers and VCSELs, as well as microLED with our Lumina MOCVD Arsenide/Phosphide platform and our Propel Gallium Nitride MOCVD system use for power electronics, RF devices, and microLED applications.

Now looking at our data storage market, we've been experiencing consistent growth for multiple years, driven by cloud and data center demand. Our Ion Beam technology enables our customers to increase the aerial density of their read, write heads, this improves performance in their high capacity drives using cloud and data center applications. Additionally, the absolute number of heads shift has been increasing and is forecast to continue to increase for several years. Based on our visibility in this market, we expect strong performance to continue through 2021. And finally, our scientific and other market is largely driven by sales to governments, universities, and research institutes. We experienced lower sales in this market in 2020 compared to 2019, which we believe was due to COVID-19 impacts.

Now turning to our 2021 priorities. With the actions we've taken to execute our transformation and positioning Veeco for success, as John said, we expect significant revenue growth in 2021. As we move toward that near-term goal, we are keeping our four main priorities in mind. First, we will maintain resiliency and flexibility across all aspects of our operations. Second, we will continue to focus on products and services that align with market trends and generate the strongest results for our customers and shareholders. Third, we will execute relentlessly on our near-term transformation objectives. And four, we will continue our efforts to position Veeco for longer-term growth in 2022 and beyond. With these four priorities in mind, we are committed to making a material difference and building a stronger Veeco that serves all our stakeholders.

And with that, John and I will be happy to take your questions. Operator, please open the line.

Questions and Answers:

Operator

Thank you. [Operator Instructions] We'll take your first question for Patrick Ho with Stifel.

Patrick Ho -- Stifel, Nicolaus & Co. -- Analyst

Thank you very much and congratulations on a nice into the year and the outlook for 2021. Bill, maybe first off in terms of the laser spike anneal business. It's great to hear that you're getting a second application entry with a customer. As the industry continues to migrate especially in the logic and down every shrinking nodes and with the future of gate all around. Do you see the potential applications continuing to increase or have you kind of reached a saturation point, let's say two applications?

William J. Miller -- Chief Executive Officer

Yes. Thanks, Patrick. We really love that question and here's why. In the short term, laser annealing is really driving our business in '21. You just mentioned the second application win at one of our existing customers, that's certainly driving us in '21. But longer term, we see opportunities, we're working with our existing customers at their next nodes, we're replacing evaluation systems there. We're actually closely engaging a third logic customer with an e-val at their most advanced nodes. And we recently placed two tools at a DRAM memory customer, which is really the first penetration we've had into memory. And it makes a lot of sense because memory lags behind logic update and what we're seeing is, as the nodes advance and the technologies change from say FinFET to Gate-All-Around, the one thing that remains is the need to continuously reduce the thermal budgets, heat to a high temperature for a shorter duration of time. And our laser annealing product is uniquely positioned to take advantage of that. So we see very bright horizons not only this year but probably continuing on as we open up the memory markets and fill more slots, if you will with the annealing steps with our existing and hopefully new customers.

Patrick Ho -- Stifel, Nicolaus & Co. -- Analyst

Great. That's really helpful. And maybe as my follow-up question for John, given that you saw a pickup in several of your businesses in the December quarter, the demand on the semiconductor side remains healthy going into the New Year. Your working capital management was very strong, in spite of the increase in demand. DSOs are very attractive levels and even as inventory is building. Can you give me the puts and takes of that working capital management? And secondly, how the supply chain looks for you right now, given that at various parts of the ecosystem, there are some supply shortages?

John P. Kiernan -- Senior Vice President and Chief Financial Officer

Sure, Patrick. So on the working capital side, we did see a slight increase in the inventory but that did decrease the days outstanding given the increase in volume. As Bill mentioned, we do see investments coming in '20, 2021, both on our increase in revenue, as well as increasing the amount of evaluation tools that are being placed into the field expected to be put in place in the field in 2021. So we will continue to try to match that working capital requirement as efficiently as possible. On the second part of your question, regarding supply chain and there, we have been effectively able to manage the increase in demand there. We've not seen any significant impacts to our supply chain at this point. And at this point, it was pretty solid.

William J. Miller -- Chief Executive Officer

I guess I'll just add one other comment there, John. We have resourced a few hundred parts from regions that have been more COVID hit and we've successfully been able to do that. And our supply chain and operations organization has done pretty amazing job there.

Patrick Ho -- Stifel, Nicolaus & Co. -- Analyst

Thank you very much.

Operator

And let's take our next question from Brian Lee with Goldman Sachs.

Brian Lee -- Goldman Sachs -- Analyst

Good afternoon. Thanks for taking the questions. Maybe just quick housekeeping one, I know the revenue in Q4, you said you had some sort of legacy MOCVD for LED that was in there. Can you quantify just trying to back out what that would have been, and then also at the margin impact was for the quarter?

John P. Kiernan -- Senior Vice President and Chief Financial Officer

Yes, yes. Brian, it's about a $10 million for the quarter at very low gross margin.

Brian Lee -- Goldman Sachs -- Analyst

Okay, great. That's helpful. And then in terms of Q1 or the 2021 updated outlook for revenue are you embedding anything in those numbers for the legacy MOCVD? I guess one of the reasons I ask is, the 40% to 42% gross margin for Q1. I know there's a bit of mix you mentioned in there, but how should we think about just generally the gross margin cadence moving through the year? Because it seem like you guys were 42% to 44% pretty consistently for a couple of quarters before the mix issue in Q4?

John P. Kiernan -- Senior Vice President and Chief Financial Officer

Sure. Sure, Brian. So we're currently viewing Q1 gross margins in the 40% to 42% range, and that reflects the existing product -- expected product mix and including wrapping up sales slow moving inventory, we've got about $5 million and that's we pretty much conclude the program there. So a little bit of a lesser extent of the gross margin impact in that 40% to 42% range in Q1 of 2021. Q1 gross margins are also impacted by the cost of support, our semi evaluation growth initiatives. As Bill mentioned, and we've mentioned, in the past with these evaluation tools, we are making investments in advance of revenue. So while we aren't providing specific 2021 gross margin guidance, Brian, we did give an updated revenue guidance for the year at $520 million to $540 million, which is 17% growth at the midpoint and an EPS for the year for $1 to $1.20 on a non-GAAP basis, which is 29% growth at the midpoint.

But let me give you a little bit more color on the gross margin. As we've indicated that this increased volume would generally give us gross margin benefits, but we're going to consume those benefits that we'd normally see with the increased volume within investments in the service capability to support the number of evals. And now that we have more clarity, we see tremendous tool for our technology and our planning for success. So typically, we'd have one to two evals in the field at a time in 2021, we expect the evals to reach about 10 in the field. And many of these evals would have a period lasting more than one year or so. So as a result, there'll be limited amount of benefit that we get to 2021 revenue from these increased evals. So we're supporting these evals ahead of revenue and we're planning for growth in 2022 and beyond.

So these investments are providing some headwinds to gross margin in 2021. And while we expect quarter-to-quarter variations in gross margins, we currently view the Q1 gross margins in the 40% to 42% range as the low point for 2021 and view quarterly gross margins in the range of 40% to 44% in the quarters as we move forward.

Brian Lee -- Goldman Sachs -- Analyst

Okay. So it's a low point for the year. That's super helpful. And then maybe just last one for me, nice boost to the revenue outlook here. I'm just wondering, can you give us a bit of quantification? I know you mentioned some figures around backlog and things ended the year on a strong note, but where are you seeing some of the pockets of strength here with respect to the new segments that gave you the confidence to raise the revenue outlook. And then maybe just related to that, you had a fairly sort of flattish growth to revenue in 2020, and then in the back half, you kind of picked it up. Similar cadence, we should expect in '21, it seems like you're starting out '21 with a pretty good range here. So it almost implies maybe a flatter revenue trajectory, you can get to the $520 million or $530 million, if we're thinking about the outlook here.

William J. Miller -- Chief Executive Officer

Yes. Let me take the first piece of that. Maybe John can answer that second half. What we've been saying is, we see growth in 2021 from three areas, laser annealing, 5G RF and data storage. And the data storage piece of our business is on long lead times. And well, we put out our 10% up to $500 million range that fully baked in the data storage piece. So I look at that incremental step up that's really driven by planned growth or expected growth in the laser annealing and the 5G RF segments. So I think those are the two pieces that drive that incremental growth in the numbers.

John P. Kiernan -- Senior Vice President and Chief Financial Officer

Yes. And then Brian to answer the second part of your question, given the backlog visibility and when shipments are required, current view is that we would see to your point lesser of the bills in the second half of the year for 2021 in our current view compared to 2020.

Brian Lee -- Goldman Sachs -- Analyst

All right, thanks guys. I'll pass it on.

William J. Miller -- Chief Executive Officer

Thanks, Brian.

Operator

We will hear next from Tom O'Malley with Barclays.

Thomas O'Malley -- Barclays -- Analyst

Thanks for taking my question, and congrats on the next top line. I just wanted to dive in to the data storage segment. It looks as though it fell off kind of sharply in December. And you mentioned that the backlog was very strong there and called out 2Q and 3Q or calendar '21. Can you talk about, just to put some pictures, what happened there? Did customer demand fall off, or if it was getting pushed to the right? Any color there would be really helpful?

William J. Miller -- Chief Executive Officer

Yes. Sure, Tom, I would say there's been no push out of demand or anything. This is now that we're breaking data storage out as its own segment, you can see, it can be a bit lumpy. These tools have ASP is from $5 million to $10 million. And so it doesn't really take much to move the number around I would expect that number to increase going forward in Q1. So I think we have a substantial piece of backlog that will shift -- scheduled a shift in Q2 and Q3. So I think we'll see that that increase in Q2 and Q3. So I wouldn't read, I wouldn't be much into that fluctuation in quarter before.

Thomas O'Malley -- Barclays -- Analyst

Okay. And then just as a follow-up with data storage improving into Q1, obviously you're guiding down sequentially that $40 million. Can you give us a little color on what's weaker in terms of your segments or just any color on the moving parts into Q1, just given that we have the new segments here, it'd be helpful to kind of have a foot to start the year?

William J. Miller -- Chief Executive Officer

John?

John P. Kiernan -- Senior Vice President and Chief Financial Officer

So we did mention, we have a little less spell off of slow moving inventory in the first quarter. That's a piece of it. And I would say that, there's nothing else that would be individually large driving down the midpoint of our range in Q1.

Operator

And we'll go ahead and take our next question from Rick Schafer with Oppenheimer.

Rick Schafer -- Oppenheimer & Co. Inc. -- Analyst

Yes. Thanks and add my congratulations, guys. I guess I had a quick question on backlog, I think obviously with the latest numbers, and as you said, your backlog, I guess, with the new numbers support pretty high teens type growth this year, based on your guide. Sounds like demand signals are up taking pretty broadly. So I guess I'm curious, how much upside? What is the potential and terms of upside based off your new guide today in terms of what you can support. And I know you probably can't quantify exactly, but I'm just sort of wondering, at these levels, are you kind of thinking you're sort of sold out -- obviously, sold out for the year? I know you've made that comment. I believe, Bill, about your data storage segment in particular being pretty close to sold out this year. So I'm curious sort of where that upside had drew might come from this year, which segments might have some room left this year?

William J. Miller -- Chief Executive Officer

Yes. Let me start and John fill in some of the details. Our data storage is pretty close to sold out for the year. So we really are not going to be driving growth in that segment. We did just very recently win second application in laser annealing and that could probably drive -- is driving growth as well as 5G for RF filters and RF devices for wet processing. So those are on shorter lead times. So if I were to say, where we would have any upside from here, what I'll really only be able to come from those shorter lead time products. John, let's try into and add anything to that.

John P. Kiernan -- Senior Vice President and Chief Financial Officer

I think that's right, Bill. We are -- as we mentioned, looking to add capacity going forward for laser annealing would be announced. Capacities expansion we're planning on in San Jose in terms of being able to increase the production footprint there. And we're running at fairly high capacity in our wet cleaning product line for 5G as well at this point.

Rick Schafer -- Oppenheimer & Co. Inc. -- Analyst

Can I ask to follow-up on that comment, John, how does that capacity sort of come online for you guys in terms of, obviously raising your ceiling on what your top line looks like? I'm thinking of next year, even, I mean, does this capacity start to become available to you say second half this year? Is it more of a '22 phenomenon? I know you've mentioned that it's probably going to be up an overall gross margin drive the investment probably well into next year, but I didn't know when that capacity would start to kick in? Thanks.

William J. Miller -- Chief Executive Officer

Sure. Some of it will be a mix of internal capacity versus using outsource in-contract manufacturing. So we're starting on the wet processing side to use contract manufacturing and from the laser annealing product line that's mainly going to come from in-house manufacturing growth.

Rick Schafer -- Oppenheimer & Co. Inc. -- Analyst

Thanks you, guys.

We'll take our next question from David Duley with Steelhead Securities.

David Duley -- Steelhead Securities, LLC -- Analyst

Yes. Can you hear me?

William J. Miller -- Chief Executive Officer

Yes.

David Duley -- Steelhead Securities, LLC -- Analyst

Sorry. I had technical difficulties with call. So thanks for taking my question. I was wondering, could you just take a step back in the LSA business and elaborate as to why customers are perhaps shifting back to laser spiking annealing from the flash technology. What is it -- at these advanced nodes -- that is driving that trends, shifting back toward your technology? And as a follow-up to that is, could you help us size the market now for LSA?

William J. Miller -- Chief Executive Officer

Yes. Let me start with a little background. We acquired this from Ultratech and they actually had success at the 28 nanometer node with laser annealing and they weren't able to continue their position at the next node. And so when we got in there, we put a pretty concerted effort into understanding why they lost their position. And we listened to the customer and we put a lot of effort into supporting and servicing the customers. And so I think the technology has some real legs and value, and what's happening at the -- as the nodes continue to shrink to five and three and two and beyond, the thermal budgets, as I mentioned, become a real challenge and the ability of the wavelength of our laser to have that energy be absorbed uniformly over all kinds of different materials on the surface of a semiconductor device is really important as well as the ability for us to scan the wafer very quickly and heated to very high temperatures and then cool it very rapidly with each consecutive node, customers are pushing us from 200 microseconds to 150 microseconds to 100 microseconds. And so there's a real roadmap in terms of thermal budget that we're working very closely with our customers to execute. And I think we're seeing the fact that flash just can't heat and cool fast enough at these more advanced than annealing steps. As now we're also seeing a memory customers have the same set of challenges that the logic guys were facing a number of years ago, if you will.

David Duley -- Steelhead Securities, LLC -- Analyst

Okay. That's right.

William J. Miller -- Chief Executive Officer

And second half of your question, yes?

David Duley -- Steelhead Securities, LLC -- Analyst

As far as, you've mentioned, you've moved your breakouts of your business around. I think it's the first time in sometime you talked about advanced packaging order, perhaps give us a little bit more detail what you might be seeing in that particular market?

William J. Miller -- Chief Executive Officer

Yes. We actually, if you look back historically, this has been a good base business, healthy business kind of in fan-out wafer level packaging, copper pillar, bumping, we've been shipping to OSATs and IDMs. And I think last call, we said, our order pipeline was increasing. Clearly now we are seeing an uptake in demand going forward. I would say our visibility is improving. We do operate this business at fairly short lead times. And so our visibility is certainly improving as we move forward into 2021.

David Duley -- Steelhead Securities, LLC -- Analyst

And just as a follow on to that particular question, is it just one customer, or is it a broad base of customers that you're starting to see greater visibility and plans to increase their CapEx for advanced packaging?

William J. Miller -- Chief Executive Officer

Yes, David, I would say, it's broad actually. We're seeing OSATs, IDM foundry, we're seeing some breadth to do it that we weren't see in the previous year or more.

David Duley -- Steelhead Securities, LLC -- Analyst

Great. Thank you.

And we'll take our next question from Mark Miller with Benchmark Company.

Mark Miller -- Benchmark Company -- Analyst

Thank you for your question, and congrats on your progress. Just we wanted to talk a little bit more about the backlog, if you're welcome. A little bit more about the backlog, you said data storage was going to be strong as Q2, Q3. Would you characterize the backlog is, frontend loaded, backend loaded or pretty even through a year as it ships?

John P. Kiernan -- Senior Vice President and Chief Financial Officer

So Mark, yes, we reported that the backlog was $366 million at the end of 2020. We would have more backlog at the beginning part of the year than the ending part of the year, although, specifically related to the data storage where we indicated that customers shipment requirements will be a little bit more weighted to Q2 and Q3 going into the year.

Mark Miller -- Benchmark Company -- Analyst

And what about the mix in the backlog is that going to be higher mix than what you've seen recently? Or is it similar?

John P. Kiernan -- Senior Vice President and Chief Financial Officer

Yes. So we typically with a longer lead time type of systems have a greater backlog. But I don't think proportionately that we see any big shift there in terms of the longer lead items would tend to be a larger percentage of the overall backlog, just given the lead times. As Bill just mentioned as an example in the advanced packing with lithography the lead times would typically be in the three to four month range. And as an example, the data storage you could have lead time in a nine month range as an example.

Mark Miller -- Benchmark Company -- Analyst

And the last one, if the R&D, you increased the investment -- inside investment going to be stay at similar levels throughout the year?

John P. Kiernan -- Senior Vice President and Chief Financial Officer

So we expect that as the year progresses that opex as a percentage of revenue, including R&D would come down as a percentage of the revenue as we progressed in the year. But in absolute dollars, we would expect to have increased in R&D expenses for 2021 over 2020.

Mark Miller -- Benchmark Company -- Analyst

Thank you.

We'll go ahead and take our last question from Gus Richard with Northland.

Gus Richard -- Northland Capital Markets -- Analyst

Yes. Thanks for taking my question. Just a housekeeping question real quick, what was spares and service in the quarter?

John P. Kiernan -- Senior Vice President and Chief Financial Officer

Okay. Yes, we break it out. And spares and service, the Q4 was about $38 million for the quarter.

Gus Richard -- Northland Capital Markets -- Analyst

Okay. And then is certain service included in backlog or no?

John P. Kiernan -- Senior Vice President and Chief Financial Officer

Yes. That is part of our reported backlog.

Gus Richard -- Northland Capital Markets -- Analyst

Got it. And then the...

William J. Miller -- Chief Executive Officer

Obviously, most of it secured and it's pretty fast.

Gus Richard -- Northland Capital Markets -- Analyst

Yes. And so seasonally have backlog for spares and servicing in Q1, maybe a little more Q2?

William J. Miller -- Chief Executive Officer

Exactly.

Gus Richard -- Northland Capital Markets -- Analyst

Got it. And then in terms of the evals, you were talking about having 10 out this year, of those how many you got out and how many are in LSA? How many are in MOCVD and something else?

William J. Miller -- Chief Executive Officer

Yes. I would say, [Indecipherable] to approximately half are in LSA including some other advanced tools, platforms that will won't be out until the end of '21. We have some tools MOCVD tools for power electronics as well as microLED. And then we have a wet processing tool going out shortly. So that's kind of a flavor for what we have on this probably laser annealing heavy.

John P. Kiernan -- Senior Vice President and Chief Financial Officer

We got about 30% of them out at this point.

Gus Richard -- Northland Capital Markets -- Analyst

Okay. And then there's a sort of a pause in your data storage business in Q4, Q1 is active, one thing that's, as you mentioned earlier, or is there a little bit of a digestion period, any other reason for that pause?

William J. Miller -- Chief Executive Officer

Yes, I wouldn't describe it as a pause, Gus. I wouldn't say it's the size of the machines in it. It's a $6 million or $8 million machine in this quarter versus that quarter can move the numbers around. I wouldn't say, we're picking up any signs of demand change here or backlog change to push out.

Gus Richard -- Northland Capital Markets -- Analyst

Okay. That's it for me. Thank you so much.
