Jennifer Jue -- Head of Investor Relations
Thank you, operator. Good afternoon, everyone, and thank you for joining us for Amkor's first quarter 2021 earnings conference call. Joining me today are Giel Rutten, our Chief Executive Officer; and Megan Faust, our Chief Financial Officer. Our earnings press release was filed with the SEC this afternoon and is available on the Investor Relations page of our website, along with the presentation slides that accompany today's call.
During this presentation, we will use non-GAAP financial measures and you can find the reconciliation to the US GAAP equivalent on our website. We will make forward-looking statements about our expectations for Amkor's future performance based on the environment as we currently see it. Of course, actual results could differ. Please refer to our press release and other SEC filings for information on risk factors, uncertainties and exceptions that could cause actual results to differ materially from these expectations. Please note that the financial results discussed today are preliminary and final data will be included in our Form 10-Q.
And now, I would like to turn the call over to Giel.
Giel Rutten -- President and Chief Executive Officer
Thanks, Jennifer. Good afternoon, everyone, and thank you for joining the call today. Today, I will review our first quarter performance and will provide the outlook for the second quarter. I will also make a few comments on dynamics in markets and technologies that Amkor is well positioned for future growth. The continued strong demand in our advanced technology and steady progress in our mainstream business, we delivered solid financial results in the first quarter.
Revenue of $1.33 billion was a Q1 record, increasing 15% year-over-year and declining only 3% sequentially over all-time record Q4 2020. Continued momentum exiting the year resulted in sequential increases in all end markets with the exception of communications, where we saw a moderate seasonal decline. Profitability for the quarter was above the high end of guidance with a record Q1 EPS of $0.49.
Within communications, the first quarter sequential decline of 15% was in line with expectations and was less than the past few years. Typically we expect seasonal Q1 decline in the range of 25% to 30%. Year-on-year, our communications business grew 22%, representing 40% of total quarterly revenue. For full year 2021, we expect continued growth in our communications business, driven by strength in the smartphone market and a further proliferation of 5G technology.
Market data forecast smartphone volumes to increase 9% year-on-year and 5G penetration rate increasing to around 40% or 540 million units in 2021. First quarter revenue in the automotive and industrial end market was strong, recovering to pre-pandemic levels and setting a new quarterly records. We had sequential growth of 9% and year-on-year growth of 11% in the quarter, representing 22% of total revenue.
We have continued strength in advanced products, as well as continued growth in our mainstream and automotive portfolio, most notably in Japan. For the second quarter, we anticipate that supply chain constraints, especially in the wafer and substrate supply chain will hold back further growth and we expect the second quarter automotive revenue to be relatively flat versus Q1.
For the second half of the year, we anticipate the automotive supply chain will gradually recover, resulting in further growth. Going forward, we believe the growth drivers in this market remain in place and the semiconductor content per car to further increase due to accelerated proliferation of driver assistance electronics and the electrification of more car models.
The consumer market returned to quarter-on-growth with an 8% sequential increase in line with expectations. IoT wearables continued to be an important driver for growth. Although, some supply chain constraints and expected product pipeline changes continue to be dynamic in this emerging product categories. Our overall product and customer pipeline for devices and advanced SiP solutions in the consumer market remain strong. We are confident that the end market for IoT devices will continue to be a growth area for Amkor.
Revenue in the computing end market set a new all-time quarterly record with sequential growth of 2% and a year-on-year growth of 30%. We experienced good performance in all computing applications and the strengthening of our project pipeline. We expect the computing market to drive further growth for outsourced assembly and test services and we anticipate growth in multiple applications ranging from personal computing to infrastructure and data centers. Over recent years, we have established a proven technology portfolio with required manufacturing scale. And Amkor continues to invest in capacity and technology for this market.
With a technology base ranging from larger body size flip chip, multi-chip modules [Indecipherable] and High Density Fan-Out we were able to offer customers a complete solution in this domain. With growing demand for high-performance package technology, we strengthened our engineering teams to develop specific solutions together with lead customers. These engagements allow us to introduce key enabling technologies, for example laser system bumping and high conductive thermal materials to resolve technical challenges.
The new technologies enable us to capitalize on opportunities not only in the computing domain, but also to extend these capabilities in other areas like automotive. Finally, our test business grew 15% year-over-year in Q1 as we increased the scope of our test services for 5G communication and system level testing and continue our focus on expanding test attach rate. Strong demand in the quarter resulted in good factory utilization and we saw utilization improvement especially in our Japan factories.
Our wafer-level and flip chip production lines were highly utilized and utilization rates in our lead frame and wire bond factories further improved with the recovery in the automotive and industrial markets. The high factory utilization contributed to a solid 20% gross margin for Q1. To prepare for future growth, our manufacturing organization is expanding clean room space in our facilities in Korea, China and the Philippines and we are further ramping our new T6 factory in Taiwan. We also have been watching closely the growing interest on activity in US semiconductor manufacturing and the new US forward looking investment policies. We are encouraged by efforts to fund the chips for America initiatives and are actively exploring to be part of the US semiconductor manufacturing supply chain.
Capex for the year is expected to be around $700 million, the capital intensity in the low teens. Major investments in 2021 are planned for wafer level and flip chip technology, SiP capacity, test capacity and the facility expansions I've mentioned previously. We also plan specific investments to support our industry for that O program, enabling an intelligent factory framework to improve quality, decision making speed and asset utilization.
Now, let me turn to our second quarter outlook. We are expecting another solid quarter, with revenue of $1.34 billion at the midpoint of guidance. This represents a year-on-year increase in Q2 of 14%. Short-term capacity constraints for wafers and substrates are expected to impact parts of the semiconductor supply chain, especially in the automotive market, limiting further growth in Q2. For the full-year 2021, we expect continued strength in all growth areas, particularly 5G communication and computing. We remain confident in our strong market position and the overall demand environment and expect to outgrow the semiconductor market in 2021.
Megan will now provide more detailed financial information.
Megan Faust -- Chief Financial Officer
Thank you, Giel. And good afternoon, everyone. Today, I will review our first quarter results and then provide some comments about our second quarter outlook. As Giel noted, first quarter sales of $1.33 billion was a quarterly record, up 15% year-on-year and a modest 3% sequential decline from an all-time record in the fourth quarter of 2020. In our memory business, we see an accelerating trend toward advanced SiP solutions in addition to multi-layer die stacking. Memory is now more dependent on advanced technology. And therefore starting this quarter we are reporting memory in our advanced products category. Previously it was in mainstream. For comparability purposes, we have recast prior periods.
Advanced products have grown 16% year-on-year in the first quarter and represent approximately 70% of our business. Our mainstream products have recovered to pre-pandemic levels of over $400 million in the first quarter and now represent around 30% of our business.
Strong demand throughout end markets resulted in continued high utilization across our factories and product lines. This had a positive impact on our profitability. Year-on-year gross margin expanded 360 basis points, reaching 20% for Q1 and demonstrating the leverage in our model of 40% to 50% incremental margin.
Operating expenses for the quarter came in as expected at $121 million, resulting in operating income margin of 10.9%. Research and development cost increased over 35% or $12 million year-on-year, reflecting the strength in our project pipeline for advanced products, most notably for advanced SiP. Several projects are planned for high volume ramps in the second half of 2021.
In addition, multi-year growth catalysts are anchored in advanced packaging technologies and we are committed to investing in key R&D programs to meet our customers needs. Net income for the quarter was $120 million, resulting in record Q1 EPS of $0.49. Q1 EBITDA increased over 30% year-on-year to $280 million and EBITDA margin was 21%.
We ended the quarter with over $800 million of cash and short-term investments and total liquidity of $1.2 billion. Our total debt as of March 31, 2021 is $1.1 billion, the lowest in over 20 years. We also continue to optimize our cost of debt and have reduced our quarterly interest expense by 25% year-on-year. Our strong balance sheet positions us well to continue to invest in growth opportunities.
Moving on to our second quarter outlook. We expect revenue to be between $1.29 billion and $1.39 billion. Our guidance considers an estimate for supply chain constraints that are expected to temper growth. We anticipate these constraints to ease in the second half of the year. Gross margin is expected to be between 17% and 20%. Gross margin in Q2 is modestly constrained by factory preparations for second half growth.
We expect Q2 operating expenses of around $120 million flat with Q1. We expect our full-year effective tax rate to be around 18%. Q2 net income is expected to be between $77 million and $127 million, resulting in EPS of $0.32 to $0.52. Our forecast for capital expenditures for the year remains at $700 million to support strong demand expected in 2021 and beyond.
With that, we will now open the call up for your question, operator?
Questions and Answers:
Operator
Thank you. Ladies and gentlemen, at this time we'll be conducting a question-and-answer session. [Operator Instructions] Our first question comes from Randy Abrams with Credit Suisse. Please state your question.
Randy Abrams -- Analyst
Okay. Yes, thank you and a good result. I wanted to ask a first question about the supply constraints for the two areas. First on substrate, is it mostly on the auto and lead frame or are you assessing the substrate constraint extend to some of the high-end ABF substrate? And on the wafer constraint, is that more an issue of the foundry side, was that somewhat related to IDMs where we've had -- one of the Japan companies had an incident and there's also been constrain in IDM capacity. So I'm curious to hear you on both of those constraints? And then just the outlook or implication for second half, normally you have a good seasonal ramp up. And so just wanted to see how much the constraint may impact the fees over if you normally have into third quarter?
Giel Rutten -- President and Chief Executive Officer
Okay. Hi, Randy, this is Giel. Let me start with the first question on supply constraints -- supply chain constraints. Starting with the wafer supply chain, your question was related, is it only IDM factories or does it go deeper into the supply chain? Actually it is both, of course, it started very much with IDM factories both in Japan, as well as in the US that got constraint, industrial incidents like fire or here the storm in Texas.
But of course, most of these customers are also relying on the same technology, which are generally older technology nodes on supply from foundries. So while the internal factories are ramping down, you see also constraints happening on the foundry side. So we see that's definitely happening in the second, third quarter, but we see clear improvements going into the third quarter for the wafer supply.
With respect to the substrates, it is indeed on the lead frame and the lower-end part of the substrate side that we see constraints. But also there on the same elements we see also pockets of constraints on the higher end substrates impacting some of the compute segment. So there are selective areas where we see constraints happening also on the higher end substrates.
Does it answer your question, Randy?
Randy Abrams -- Analyst
Yeah, that does. Maybe just the follow-up on second half implication, it sounds like the wafer substrate better, not sure on the lead frame, but if you expect there could be a limiter for the normal ramp or you see it actually better and or good enough in both areas?
Giel Rutten -- President and Chief Executive Officer
Yeah, we consider being being improved in both areas, Randy. Also on the lead frame area, we see some improvement, it has to do with the special metal supply chain and we see that these companies are actually getting their volumes up for the second half of the year. So we see improvements across the board, definitely will start impacting the third quarter and we hope that we see a more normalized supply chain in the fourth quarter.
Now going back to your outlook for the second half of the year, normal seasonality, let me first comment on the second quarter outlook, I mean, normal seasonality typically for us is a 5% increase over the first quarter. Currently, we see 1% increase and the buyouts more than 50% of that is attributable to direct impact of customers supply chain. The other half may be, let's say, build volumes impacted indirectly. So overall, we see an impact of about 3% to 4%. For the second half across the board, we see strong demand environment both on the mobile side, as well as on the automotive side with improvement in the supply chain. So, we're confident that there is strength in the second half of the year.
Randy Abrams -- Analyst
Okay. And it's also higher based in first quarter for the seasonal for Q1 and Q2. And second question I have on the system and package, you talked a bit about this pipeline transition, is there any headwind in the first quarter to second quarter seasonality or transition of product? And if you could give a view just on how the SiP overall is tracking for the full year or what you kind of see filling in the pipeline that could come through later this year on System-in-Package?
Giel Rutten -- President and Chief Executive Officer
Yes, in the consumer domain, let's say more broadly System-in-Package is driven by two market segments, I mean, one is consumer, the other one is communication. In the consumer domain we see change over one -- from one product generation and to other product generation meaning one is ramping down the other this ramping up.
We also see our customer base expanding and that shows let's say dynamic environment in the second quarter, but also going into the second half of the year. Keep in mind that this product category is also to some extent impacted by the substrate and wafer supply. If you look to the wafer supply, it's all the node and that heavily impacts power management products. So actually all areas in the industry are impacted by that. On the communication side for the second half of the year, we see strong ramp that multiple products in line with the second half ramp for in the mobile market.
Randy Abrams -- Analyst
Okay. And a question on actually two sides, one is on equipment, if there is any constraint for the equipment -- on your capacity is there any limitation either on the advanced or on wire bonding where some of the stretching lead time on equipment is having much impact?
Giel Rutten -- President and Chief Executive Officer
Yes, I think on the equipment lead time, that's your question. Lead times generally expanding for all equipment, whether it's wire bonder or wafer source or other equipment. We started to observe that actually in the latter part of 2020 and proactively let's say orders -- the anticipated capacity at that point in time we foresaw to meet in this year.
I mean most notably the lead time expansions are in wire bonds for example. I think we are currently able to get the numbers that we need, but they're definitely are delayed into let's say into the second and third quarter when it comes to delivery. So far I would say it's not the bottleneck, the bottleneck in the industry is currently, definitely are the material supply and we don't expect that for Q3 and even Q4 that equipment availability will be the bottleneck for further ramps.
Randy Abrams -- Analyst
Okay. And just last question, if you could talk on the pricing outlook where the Asian peers I think have been opportunistic to raise pricing, how you're seeing that the pricing and also given the tightness in the industry if any customers are doing any kind of contracts, looking at further out lock in supply and if they are -- if that's coming up pricing or way to be pricing?
Giel Rutten -- President and Chief Executive Officer
Yes, let me start with the first part of your question with respect to the pricing environment. In general, we see cost of our products going up, I mean, cost of material is going up and that's to partly let's say the result of the shortage of some of the materials, specifically on the substrate and lead frame side. But also for example on gold wire and even copper wire prices are significantly increasing.
So if we see cost increases, we work with our customers to adjust pricing versus these cost increases, I think that's a constructive dialog with our customers. Now in our part of the supply chain there for example on the wire bond business, we work mostly with automotive customers. We have longer-term contracts, we don't work on tactical pricing with our customers. So on very rare occasions we will do that, but in general we don't tactically use price increases other than increases for material price increases.
With respect to your second part of your question, longer-term contracts. Yes, I think we see that, we see longer-term contracts in different parts of the business to secure capacity and to secure supply. We also see different business models occur in there like co-investments in specific part of the share of the business and that happened before, but clearly intensifies this part of the year.
Randy Abrams -- Analyst
Okay, great. Thanks a lot for the color, Giel. Good luck.
Giel Rutten -- President and Chief Executive Officer
Thank you, thanks, Randy.
Operator
[Operator Instructions] Thank you. Ladies and gentlemen, there appears to be no additional requests for questions at this time. I would now like to turn the call back over to Giel for closing remarks. Thank you.
Giel Rutten -- President and Chief Executive Officer
Okay. Thank you, operator. Well, before closing the call, I would like to recap a few key messages. First, the first quarter of 2021, we delivered record Q1 revenue of $1.33 billion and EPS of $0.49. For Q2 2021, we expect another solid quarter with revenue of $1.34 billion, a 14% year-on-year growth. Supply chain constraints will limit second quarter growth, especially in the automotive market. We expect the supply chain to gradually recover in the second half of 2021.
We believe that the main growth drivers remain in place and with Amkor's position in key growth market, we expect to outgrow the semiconductor market in 2021. And last but not least, I would like to thank the global Amkor team for delivering another great quarter. Special thanks for the team's resilience to overcome the challenges we continue to face as a result of the ongoing pandemic and thank you for joining the call today.
