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 progress we made in Q4 and over the course of 2021. I'd like to start by thanking the Veeco United team for outstanding execution through the ongoing pandemic and dynamic supply chain environment. To begin today, I'd like to share some exciting news. We recently won a laser annealing application at a new leading-edge logic customer. This is a key milestone for us as we execute our growth strategy. More on that in a few minutes. But first, I'll take you through our 2021 and fourth-quarter highlights. John will provide a financial update and guidance, and then I'll discuss our markets and technologies before taking your questions. Reflecting on the year, I'm proud of what our Veeco United team has accomplished. I think of 2021 as an inflection point at Veeco, where we completed our transformation, and we're now squarely executing our growth strategy. We continued our focus on innovation with R&D projects supporting laser annealing, ion beam deposition for semiconductor applications, and MOCVD for power electronics and photonics applications. We now have a more robust evaluation program in place with systems installed and performing well at many customer sites. We made great progress on our capacity expansion and shipped first systems from the new San Jose facility, and we enhanced both our service capability and our service offerings, focusing on our customers' needs for system uptime and spare parts availability. Results of our growth strategy were reflected in our P&L with significant revenue growth in 2021 and profitability growing faster than revenue. We had a record year in our semiconductor market, and we had a record year with our wet processing systems. We made further improvements to our capital structure. Also, we issued a long-term model at our Analyst Day in September, demonstrating our optimism and confidence in our future performance. And lastly, we continue to make great strides improving our governance, our commitment to corporate responsibility and our Veeco United culture. All in, we're thrilled with our progress in '21 and equally excited about our growth prospects going forward. Switching gears to our full-year financial highlights. 2021 was a significant year of growth for Veeco. Revenue for the full year was $583 million, a 28% growth over 2020, driven by semiconductor and data storage performance. This growth came with significant profitability, driving $87 million in non-GAAP operating income and $1.43 or 66% growth in diluted non-GAAP EPS. We had significant cash flow from operations of $68 million, a 58% increase over 2020. Our order intake grew faster than our revenue throughout the year as well, with bookings of $661 million and a book-to-bill ratio of 1.13, we ended the year with $440 million in backlog. Now for a look at our Q4 2021 highlights. Q4 marked another quarter of solid execution driven primarily by strength in our semiconductor market. Revenue came in at $153 million, which was above the midpoint of our guidance and diluted non-GAAP EPS came in at $0.43, which was near the high end of our guidance. We achieved non-GAAP operating income of $25 million. In addition, we generated $17 million in cash flow from operations. With Q4's performance, we exit 2021 on a positive note with strong order momentum, increased backlog and focus on execution. And with that, I'll turn the call over to John for more details on our financials.

Thanks, Bill, and good afternoon, everyone. Today, I will be discussing non-GAAP financial data and 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. Looking at full-year 2021, revenue came in at $583 million, a 28% increase from 2020. Breaking down by market, our semiconductor revenue was $247 million, which represented 43% of the total and an increase of 49% over the prior year. On top of that growth in 2021, we expect significant growth in 2022 on strength across the board in laser annealing, EUV mask blank and AP lithography. Compound semiconductor revenue was $107 million, flat from 2020 and made up 18% of the total. However, normalizing for about $20 million of one-time commodity LED sales of slow-moving inventory in 2020, the $107 million in 2021 represents underlying growth in the areas where we currently focus. Furthermore, we expect significant growth in the compound semiconductor market in 2022, which is based on our backlog and visibility of MOCVD and other systems selling primarily into photonics applications and secondarily, GaN Power. Data Storage revenue was $169 million, a 37% increase over the prior year and made up 29% of our total revenue as hard disk drive customers continued adding capacity for their magnetic head manufacturing. And scientific and other revenue was $60 million, an increase of 6% from 2020 and made up 10% of total revenue. And looking at full-year revenue by region, the United States made up 38% of the total revenue driven by data storage customers. Our Asia Pacific region, excluding China, made up 35%, driven by semiconductor customers. China made up 18%. And finally, EMEA was 9% of total revenue for the year. Turning to Q4 revenue by market and geography. Revenue totaled $153 million for the quarter and was driven by strong performance in our semiconductor market, which made up 43% of our revenue, driven by multiple laser annealing and advanced packaging lithography systems. The compound semiconductor market contributed 23% of our revenue and was driven by multiple system shipments for 5G RF applications and shipments to photonic customers. Our data storage market came in at 24% of total revenue. And finally, the scientific and other market made up 10% of our revenue. Now looking at our quarterly revenue by region. The United States was 37% of our total revenue driven by data storage customers. Our Asia Pacific region, excluding China, made up 26% driven by semiconductor system sales. China made up 25% of total revenue, primarily driven by semiconductor systems with particular strength in trailing node laser annealing as well as compound semiconductor systems led by wet processing and ion beam systems for RF power amplifiers. And finally, EMEA was 12% of total revenue for the quarter. Now turning to non-GAAP operating results. On a full-year 2021 basis, we achieved gross margin of 42%, which was in line with expectations. Let me take a moment to further elaborate on our supply chain status. Throughout 2021, we saw increasing challenges as the year progressed and experienced higher logistics costs, inflationary pressures on materials and longer lead times. Our supply chain team has done a fantastic job of mitigating most issues they encounter. And overall, for the year, there was about a one percentage point impact to our gross margin. We expect the situation to be similar for a few more quarters, the impact of which has been incorporated in our previously provided guidance for 2022. Our annual operating expenses increased to $158 million, reflecting the R&D investments we've been making to drive future growth as well as higher variable SG&A expenses associated with an increase in revenue and order intake. However, year-on-year OpEx as a percentage of revenue declined from 32% to 27% and provided operating leverage to the Company. Our non-GAAP operating income increased 65%, from $52 million in 2020 to $87 million in 2021. Diluted EPS increased 66% to $1.43 for the year. And now I'll provide a few additional full-year figures. For 2021 amortization expense was $12.3 million. Our equity comp expense was $15.2 million, and our non-GAAP depreciation was $13.4 million. Cash interest on our debt was $12.5 million, and net cash taxes for the year were not material. At year-end, we had federal NOLs of $166 million and other federal tax credits of $32 million, which are fully reserved. And as a result of strong year of order intake, as Bill mentioned, we ended 2021 with $440 million in backlog, a 20% increase from 2020. We more than doubled our semiconductor backlog over the course of the year, and our compound semiconductor backlog grew by 47%. Our data storage backlog decreased by 51% as customers slowed the pace of new orders for capacity additions. Switching gears to our quarterly results. Gross margin came in at 42.4%, which was in line with guidance. Gross margins are influenced by a number of factors, and we expect quarter-to-quarter variations. Notably, we were able to maintain this level of gross margin in spite of the challenging supply chain environment while continuing to invest in service capabilities and supporting our evaluation systems in the field. Operating expenses were $40 million, flat to Q3. On a non-GAAP basis, tax expense for the quarter was a benefit of approximately $500,000, with net income coming in at $23 million and EPS was $0.43 on a diluted share count of 53 million shares. Now moving to the balance sheet and cash flow highlights. We ended the quarter with cash and short-term investments of $225 million, a sequential decrease of $111 million. This decrease was primarily due to convertible note repurchased during the quarter and was partially offset by $17 million in cash flow from operations. I'll explain the effects of the convertible note transaction in just a minute. From a working capital perspective, our accounts receivable increased to $110 million due to timing of shipments and when associated customer payments do. DSOs for the quarter came in at 64 days, up from 52 in the prior quarter. Accounts payable decreased sequentially to $44 million. Inventory was $171 million, and days of inventory came in at 173, both flat from the prior quarter. Long-term debt on the balance sheet was recorded at $229 million, a $102 million reduction from the prior quarter. This reduction is primarily due to the repurchase of a portion of the convertible notes due in 2023. In the fourth quarter, we repurchased $112 million in original principal amount for $117 million in cash. The remaining $229 million of long-term debt represents the carrying value of the $278 million of convertible notes. Our CapEx during the quarter was $9.2 million with $8 million used for the new San Jose facility build-out, bringing the CapEx total for the year to $41 million with $31 million used for this expansion. Now turning to additional commentary on our convertible notes. As outlined on the slide, after the convertible note repurchase, the January 2023 convertible note principal amount is now $20 million. There has been no change to the principal amount of the convertible notes due in 2025 or 2027. Our annual cash interest expense is expected to be $9.9 million on a go-forward basis, down from $12.9 million prior to the repurchase. In 2021, we added financial flexibility as well by entering into a $150 million revolving credit facility. With our improved balance sheet, along with our credit facility, we have the flexibility and capital to focus on driving long-term growth across the business. Now turning to Q1 guidance. Q1 revenue is expected to be between $145 million and $165 million, with non-GAAP gross margin between 42% and 44%. We expect non-GAAP OpEx to be between $42 million and $44 million. We expect GAAP net income to be between $7 million and $18 million. Non-GAAP net income is expected between $15 million and $26 million. We expect GAAP EPS to be between $0.15 and $0.32 per diluted share. Non-GAAP EPS is expected between $0.28 and $0.44 per diluted share and is based upon a 64 million share count. As we previously highlighted during our Q3 earnings call, the new accounting standard for convertible debt, ASU 2020-06 is effective January 1, 2022, which will reduce our noncash interest expense for GAAP purposes and change our method for calculating diluted GAAP and non-GAAP EPS to the if-converted method of accounting. We've added a new schedule to the guidance section of the earnings press release and backup section of the earnings presentation to illustrate how Q1 EPS would be calculated based on the guidance ranges provided and now for some additional color beyond Q1. Based on our current visibility and backlog, we are reaffirming our recently provided revenue outlook for 2022 between $640 million and $680 million. The principal drivers of this strong outlook are 35% year-on-year growth in both our semiconductor and compound semiconductor markets. And we continue to target diluted non-GAAP EPS for the full year to be between $1.50 and $1.70 per share. And with that, I'll turn it back over to Bill for a market update.

Thanks, John. Turning now to our technologies in the markets we serve in the context of the mega trends computing and artificial intelligence, which is driving faster computing in processors and GPUs for large-scale data center deployments and machine learning. The second megatrend is mobility and the immersive user experience. It includes smartphones and communications infrastructure such as 5G. It also includes gaming, AR, VR and a variety of sensing applications. Transformation of the automotive industry, including EV and autonomous driving, is another major driver today requiring semiconductor devices in the form of AI processors, logic, memory, and power devices. And finally, the cloud represents a seasonally endless source of demand for more powerful and efficient computing, higher-speed communications and higher-density hard disk drive storage. Now looking more specifically at our growth markets. In our semiconductor market, the overall backdrop measured by wafer fab equipment spending is extremely healthy. There are several analysts estimating very strong WFE growth in 2022, driven by node transitions as well as capacity additions for current and trailing nodes. While this backdrop is good news for Veeco, remember that we expect to grow our semiconductor revenue faster than WFE growth. We expect to expand our served available market as our laser annealing technology is adopted for additional logic process steps and by additional logic customers. And we've been engaged with a leading memory customer who is evaluating laser annealing for their DRAM manufacturing process. During the quarter, we experienced broad pull for our laser annealing systems from a variety of customers with multiple multi-tool orders to add capacity for advanced nodes as well as trailing node applications. Our efforts delivering and supporting our differentiated laser annealing evaluation systems have recently paid off. I'm excited to announce that we won production tool of record status with another leading-edge logic customer. They'll be introducing laser annealing in their high-volume production process at their next node. This is great news for us as it further validates our laser annealing technology and demonstrates that its thermal budgets continue to shrink. Veeco's annealing solution is becoming increasingly attractive to our customers. In addition to laser annealing, we serve the semiconductor market with our ion beam deposition systems for EUV mask blank production. EUV adoption is continuing its momentum. ASML is forecasting shipment of 55 EUV lithography systems in 2022 and over 60 EUV lithography systems in 2023 with both logic and memory driving demand. With approximately one of our systems required for every 10 to 15 EUV lithography systems in the field, we size this market at three to five systems per year for us. This market momentum is demonstrated by a recently received order for one of our ion beam deposition systems from a new EUV mask blank player. This new customer intends to use our ion beam deposition system to create the multilevel metalization stack in EUV mask blanks. Veeco's ion beam deposition is the deposition process of choice for this highly sophisticated manufacturing process. In advanced packaging, demand remains high for applications such as flip chip bumping, fan-out wafer-level packaging, and heterogeneous integration with customers seeking performance improvements for their products. We had a strong revenue quarter in lithography and we saw positive order activity across our lithography products. We expect this trend to continue for some time. Wrapping up our semiconductor market comments, we're currently experiencing strong demand from laser annealing, EUV mask blank production, and advanced packaging and expect this demand to continue and drive significant semiconductor growth in 2022. 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 compound semiconductor applications. We shipped multiple systems during the quarter to photonics customers as well as RF customers, adding filter and power amplifier capacity. Looking at our MOCVD business, we're beginning to see traction in the photonics market with a recent announcement for a multisystem order for our Lumina platform. Longer term, we believe we're well positioned for the micro LED and 8-inch GaN power opportunities with both our Lumina and Propel platforms. Going into 2022, we expect the compound semiconductor market to grow significantly. Now looking at our data storage market which has grown for years. We're expecting system deliveries to decelerate in 2022 and customers absorbed their recently added capacity. Beyond 2022, however, as cloud and data center applications continue to expand, storage demand is expected to increase for several years. At the same time, these drive manufacturers continue to develop their products with higher numbers of magnetic heads per drive, requiring additional vehicle equipment. These fundamentals of the industry and current customer activities that lead us to expect the market opportunities to improve in 2023. Now turning to our 2022 priorities. We entered the year with great optimism given today's healthy demand environment, coupled with our strong backlog position. Therefore, it's incumbent on us to protect our ability to execute. Our first priority is to keep our employees healthy and safe and maintain the progress we've been making on our culture so we can maximize our potential. Tactically, we have several initiatives in place to keep us focused on execution, keeping our supply chain moving, improving our quality and on-time delivery for our customers, and driving successful outcomes with our evaluation systems are all top of mind. Keeping an eye toward the future is equally important. We're highly motivated to fully transition to the new manufacturing facility in San Jose, advance our R&D efforts with new technologies, and deliver them to customers as new evaluation systems and further enhance our service capabilities to support our semiconductor customers. And lastly, we expect to grow revenue in 2022 while improving our gross margin as we make progress toward our long-term target model. With these priorities in mind, we're 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.

And we will go first to Rick Schafer of Oppenheimer.

This is Wei Mok on the call for Rick. Congrats on the strong quarter and your recent laser annealing announcements. So on the press release, you mentioned repeat multi-systems. I was wondering if you can expand on this, like how many systems should we think about per year? And when do you expect to start delivering them?

Yes. Thanks for the question. We're really excited that you mentioned that because our laser annealing business is going to be the largest business for us next year. And yes, we did announce multiple customers with multi-system orders. And so we're going to see nearly 50% growth in laser annealing in '22 over 2021. We're also very excited that we were named production tool of record from a leading-edge logic customer where we had an email system, and that's a huge milestone for the Company. In our opinion, that kind of shows the kind of breakthrough technology that we have in our laser annealing technology.

Great. For my follow-up, I'm inquiring about MOCVD. It seems you've delivered an MOCVD to a customer. This tool has traditionally been utilized for LED applications, but now it's being adapted for a variety of emerging uses. I'm curious if you've identified any specific applications that are experiencing quicker or greater adoption.

We have two evaluation systems in the field. One is at an 8-inch gallium nitride power electronics customer. And we have put a number of tools into the field for revenue, and we're starting to gain some momentum in power electronics. Also, we have an evaluation system, our new Lumina product that is capable of a lot of applications such as red micro LED in this application, and that evaluation is going well. But the Lumina platform is also looking very capable beyond red micro LED for applications like edge-emitting lasers, VCSELs, specialty red-orange LED applications as well. So, both of those product lines are doing fairly well albeit from fairly low levels in 2021. But we're certainly going to drive incremental growth for our compound semiconductor market in '22, the MOCVD piece.

We'll go to our next question from Tom O'Malley of Barclays.

I just wanted to ask a follow-up there on the MOCVD business. I thought in the prepared remarks, you kind of went out of your way to mention the photonics opportunity. For a couple of years now, you've been trying to get some more traction in that market. What's changing now? Is it just new tools that are proving better for customers? Or is that market starting to grow again? Because I know in the past you've mentioned the industry capacity was really full. It's now starting to loosen up a bit as well.

Tom, I would say our Lumina tool was actually a bit late to the market for the VCSEL opportunity. But that being said, it's a very capable tool, and we've now qualified it at a number of applications beyond VCSEL. And a few weeks ago, we announced a multi-tool order for our Lumina product. And that customer is using it for qualifying it for a number of applications. So we are definitely seeing some traction with the Lumina as well as the Propel for GaN-on-Silicon.

Helpful. And then my follow-up is one for John on the gross margin side. You've seen a really steady progression throughout this entire year and are guiding to a better gross margin number as well. When you look at your long-term model, you're a little more cautious there. Can you talk about why things wouldn't progress at this higher rate? Can you just walk through the puts and takes of what may rationalize margins throughout the year? Or what may keep them here?

Sure. So we did come in, in 2021 and 42% gross margin within our expectations. We talked throughout 2021 about making investments in our service capabilities and also in supporting evaluation systems in the field. And we are undertaking a number of steps to improve gross margin and probably would have done a little bit better than that in 2021 if not for some of the unexpected supply chain challenges and inflationary factors there. That being said, we continue to forecast for 2022, not really significant or any improvement in these inflationary and higher supply chain costs. But we are forecasting at the midpoint of our guide, an improvement to 43% gross margin as we take advantage of higher volumes and take advantage of some of the actions that we've taken to improve gross margin and make a step towards our longer-term gross margin goal of 45%.

We'll move to our next question from Patrick Ho of Stifel.

Thank you very much and congrats on the really nice quarter and the year. Bill, maybe first off, in terms of the advanced packaging litho business, you're seeing obviously strong activity based on the current environment. Do you believe that you're starting to see some of these next-generation processes like heterogeneous integration and some of the more advanced processes from next-generation devices? Or are we still at the early stages of that adoption?

I would say it's true that we are seeing opportunities in heterogeneous integration. That being said, we are also still seeing business in our more traditional areas like fan-out wafer-level packaging, copper pillars bumping, and high bandwidth memory. However, heterogeneous integration is definitely an opportunity for us. We have managed to take advantage of it and secure a significant amount of business, gaining some market share from both a booking and revenue perspective in 2022. We are noticing more multi-tool orders where customers are making fleet purchases, which makes tool matching very critical. I believe our position as the leader in the marketplace is holding up quite well.

Great. That's helpful. And maybe as my follow-up question for John, in terms of the new San Jose facility. You obviously ramping that up. It seems like things are going well there. You're getting products shipped out of there. But given the strong demand environment, is there any potential for incremental CapEx kind of dollars being put into that facility so it expanded a little more quickly, given the strong semiconductor demand environment that we're seeing across the board? Or are you comfortable that this current demand outlook can kind of grow into your current capacity?

Yes. That's a really good question, Patrick. So we had actually accelerated our plan in 2021. And we had previously mentioned that we were a little bit ahead of schedule despite a challenging environment in COVID and getting stuff built. So we're really happy and we did accelerate spending into this year. So on an overall basis, we continue to expect the project to cost about the same and about 3/4 of the spending this year, about 25% of the spending next year, and we're going to accelerate starting the move into the building. As you said, we started manufacturing products already. We shipped systems in Q4. And we still expect to be fully transitioned into the new space by the end of Q3 2022. So, things are moving along to plan. And as we previously mentioned that when we do get up and fully running in the new facility, it's going to have about double the manufacturing output as our current San Jose facility.

And we'll go to our next question from Mark Miller of Benchmark.

Congrats on another good quarter. You mentioned the two eval tools for compound semiconductors, and also mentioned the DRAM eval tool. Anything on the other tools, any more color on the other evals you've got in the field?

We have a number of evals in the field. As you know, we've talked throughout '21 that we're making a C state change going from one or two evals in the field to closer to 10 at any given time. And very much aligned with the Company's strategy of growing in semi and in compound semi, we have a very high concentration of tools in the semi space. And within that, we have a high concentration in laser annealing. And that's with existing customers at their next node. Third, logic customer where we recently just said we want PTOR in the future as well as a tool for DRAM manufacturing in laser annealing. These programs are moving on track, and we're really very, very content and excited about where we are at this point in the game. We also have, as you just said, two systems in MOCVD, one for 8-inch gallium nitride power electronics and one specifically for red micro LED.

In terms of the next generation logic ships, are there going to be more opportunities for laser anneal steps?

I believe there are, Mark, and what we're seeing is as the nodes continue to shrink. The requirements on the thermal budget become more and more stringent, which actually plays to the strength of our laser annealing product. So, we're hopeful. We're very much engaged with those customers on solving their thermal budget challenges as they need these advanced chips.

And we'll move to our next question from Dave Duley of Steelhead Securities.

Could you discuss the quarterly revenue trends throughout 2022? Are we expecting continued growth in quarterly revenue, or is the second half going to be stronger than the first half? How should we approach that?

So yes, we're expecting at the midpoint of our guide around a 13% to 14% increase in revenue year-on-year. And I would say that from a progression standpoint, we would expect the back half of the year to be higher than the front half of the year. We guided Q1 in the $145 million to $165 million range, so $155 million at the midpoint. So we expect slightly higher revenue in the second half of the year based upon our full year current outlook.

Okay. And at the midpoint, you mentioned growth of 13% to 14%. I'm just curious, recently, I think the calibration of WFE market is in the 15% to 20% range. And I realize you put out these targets some time ago, do you think there's upside to your numbers if the WFE market grows, let's say, 17% or 18%, which I think is kind of consensus now?

Yes. So when we just recently put out that guide in that we're reaffirming in that range and for ease of discussion here and say the midpoint is that the 660 million at the midpoint of our guide here. We're looking at roughly a 35% increase in semi business. So we're expecting with these recent wins that Bill talked about in the laser annealing side and strength in the EUV mask blank and lithography that semi will be up about 35%. Now we're also expecting compound semi to be up a like amount in 2022 as well. So, around the 35% increase there, which is driving the overall increase for the Company and is more than offsetting the decrease that we're expecting in the data storage business this year after a number of years of solid growth, and our expectation is that data storage will be down around 35%. So, really strong on the semi and compound semi side. And we entered the year Dave, with an improved backlog position at $440 million with the semi backlog more than doubling year-over-year and the PAM semi backlog increasing by about 50%. So, pretty confident where we are in the market there and the expectations for our growth rate in 2022.

Thank you for that color. That really helps. Now just final thing for me is I think you just mentioned the hard disk drive business is going to be down 30% or 35% this year. And I guess you said also that it probably grows in 2023. Could you take a guess at which quarter we see the inflection point? Is the inflection point in this calendar year where things stop going down and they start going up? Or when should we see that transition to quarterly growth in the business?

Yes. I would say, Dave, at this point, given our lead times, we feel pretty comfortable with our 2022 guide. And the activity that we're working on now is probably right just to the back half of the '22, but most likely earlier in '23. But certainly, we're seeing increased activity, and that would probably start reading out in early '23.

We will go now to Gus Richard of Northland.

Congratulations and thanks for taking my question. I was hoping you could give us a scorecard on the 10 evaluations you had set up for last year. How many of those have you won at this point? How many are still open?

We currently have seven evaluations ongoing, with three completed. Of those, four involve laser annealing in advanced logic and DRAM. We are providing support and successfully converting some of the open evaluations into business, which is encouraging. In the MOCVD segment, we have a tool designed for GaN-on-Silicon power electronics at an 8-inch foundry; this tool has been handed over to the customer, who has run wafers and received positive initial results. While it's still early and just transitioned to evaluation, those quick positive outcomes are a good sign. Additionally, we have another MOCVD tool for red microLED under evaluation, which is part of our Lumina product line and is also progressing. There's a wet processing tool evaluation in progress aimed at the RF filter market, which has been in the field for a while and is also making good progress. Overall, I would say that currently, our evaluations are advancing better than we initially expected.

Okay. And so of the evals you talked about in the beginning of last year, you've got three down and there's still seven to go.

It's important to note that we recently announced a third logic step with PTOR, and they are still keeping the evaluation open. We are continuing to collaborate with them on other complex material challenges in the annealing process. So while it's an open evaluation, it is also profitable.

I would add to that, Gus, so that we've had a few readouts signed off. We expect a few more evals to be signed off in '22. But we also expect this program of refreshing with new technologies and new evals. So I think at any point in time think about a program around 10 evals, just plus or minus when tools get shipped and signed off. But I think for us to continue to drive growth in semi and compound semi, the eval program will be a very, very important element for us.

Right. And you teed up my next question. I think the one tool that is probably going to go out this quarter is the ion beam depth tool for the semiconductor application and not EUV mask blanks. And I was wondering, is that tool still going to ship in Q1? And do you have other customers lined up for that tool for applications?

Yes, we are currently working with all the major DRAM and logic customers. We are conducting numerous demonstrations, and a few customers are progressing with full loop wafer processing. Although the process is moving a bit slower due to the new and innovative deposition technique compared to traditional methods, customer interest and engagement remain extremely high.

Got it. And then is that ion beam tool price like in hard disk drive tool? Or is it priced like an EUV mask tool?

I'd say it's probably somewhere in between.

Yes. I think, Gus, depending on the configuration and how many chambers there are, we would aim for gross margins for that product and selling price that would enable gross margins at or above the Company's average gross margin.

Got it. And then in terms of the GaN-on-Silicon, I know you're working with somebody at 8-inch. Are you working on, you shipped GaN-on-Silicon at 12. Are you working with anybody at this time on additional tools at 12-inch or any other GaN-on-Silicon for RF anywhere else?

We have recently sold a 300-millimeter tool intended for a groundbreaking approach to microLED technology, where the customer can place blue, green, and red pixels on a single 12-inch wafer simultaneously. They already possess several 200-millimeter tools and have now acquired a 300-millimeter tool as well. Additionally, we have sold GaN-on-Silicon tools at 8-inch to various customers for their specific applications. The industry appears to be shifting from 6-inch to 8-inch for GaN-on-Silicon, which is our focus for this wafer size transition. While we have several tools deployed in the field, the repeat business has been relatively limited.

Okay. And just for clarification, just for some odd reason, are those power RF GaN-on-Silicon?

Both.

And with no other questions in the queue, I will now turn the call back over to the speakers for any closing comments.

Thank you, operator, and thanks for joining the call today. We're excited about entering 2022, and I want to thank our customers and shareholders along with the Veeco United team for their continued support as we execute our growth strategy. I do look forward to updating you all at the upcoming conferences and have a great evening.

And that does conclude today's call. Thank you for your participation. You may now disconnect.
