Thanks, Mike. Good afternoon and a happy new year to everyone. We're pleased to start the year off by reporting fourth quarter revenue exceeded the high end of our guidance, growing 12% over the third quarter and resulting in our equipment business growing nearly 50% for the year. This was our fifth straight quarter of revenue growth, and it was our eighth consecutive quarter of increasing operating margins. The Onto team has done a great job unlocking operational synergies even in this environment of rapid expansion and disruptions from the pandemic and global supply chains. Despite these ongoing challenges, we expect to maintain our growth momentum into the new year with projections for first quarter revenue, up slightly at the low end and up approximately 7% at the high end of our guidance range. But before looking to 2022, let's begin with a few highlights from the fourth quarter, starting with the advanced packaging and specialty device markets, which grew by a very healthy 21% over the prior quarter. Revenue from compound semiconductor and RF manufacturers increased by 140% in the quarter and represented roughly 40% of total revenue from our specialty and packaging customers in the quarter. Our powerful combination of process control technology and process analysis software is delivering higher levels of productivity to our customers and contributed to this strong demand. As an example, a recent customer leveraged our integrated solutions to increase factory output by an estimated 10%. We see similar opportunities to increase productivity for our advanced packaging customers, especially in heterogeneous packaging. For example, by integrating our complementary inspection, lithography and software technologies into a solution we call StepFAST, we simultaneously improved productivity and yield. In the fourth quarter, we delivered our third StepFAST solution to a leading supplier of panel level fan-out technology…

Thanks, Mike, and good afternoon, everyone. I will start by providing some details on our Q4 results and then follow with our guidance for the first quarter of 2022. As Mike mentioned, we had another record revenue quarter. In fact, we had several company financial records this quarter. Our fourth quarter revenue was $226 million, above the high end of guidance, up 12% over the last quarter and up 45% over the same period last year. The revenue growth was broad-based with metrology, inspection and software all experiencing record revenue in the quarter. Breaking down the revenue by market. 48% of the sales were in our specialty devices and advanced packaging markets, which continued to strength from the previous quarter and increased 21%. That increase was driven by RF, MEMS and power customers as well as growth from the OSATs. The advanced node markets represented 33% of sales with strong memory sales being partially offset by weaker logic foundry sales in the quarter. Finally, software and services increased slightly and represented 19% of revenue. We continue to maintain strong gross margins at 55% in both the third and fourth quarters. Higher revenues, including stronger software sales were offset by supply chain and logistic cost increases in the quarter. We continue to work on product margin improvement programs and supply sourcing programs to mitigate the impact from the supply chain on our gross margin. The fourth quarter operating expenses was $54.9 million, an increase of $3.3 million from $51.6 million in the third quarter. The increase is primarily due to onboarding of new headcount to support the growth we're experiencing and variable compensation plan adjustments. We continued our quarterly operating margin improvements each quarter since the merger with a record fourth quarter operating margin of 31% and well within our published…

Thank you, Steve. Looking broadly at the industry, we see a growing number of end markets being enabled by advances in semiconductor technology for wireless communication, high-performance compute, power devices and sensing. These new end markets are simultaneously increasing the need for additional chip capacity as well as advances in manufacturing process technology to make future devices faster, smaller and greener. At Onto Innovation, we are collaborating closely with leaders across the semiconductor value chain to deliver the manufacturing solutions needed to accelerate their road maps and fulfill expanding end market demand. These partnerships strengthen our ability to serve core markets while also opening the door to new markets. We estimate an increase of $650 million in new addressable markets spanning substrate, device and packaging. This should provide additional tailwinds independent of projected industry growth over the next several years. Zooming into the first quarter guidance Steve just outlined, we project revenue from memory customers in both DRAM and NAND will increase by over 50% in the quarter. As we mentioned earlier, our integrated suite of metrology is providing important value to our customers. As an example, we're contributing to yield improvement at one of our largest 3D NAND customers by aggregating Atlas OCD with integrated and films metrology data. This aggregation is providing a more complete view of deposition, etch and CMP process steps, again, it's speed suited for high-volume production. For the year, we see NAND continuing to be strong with capacity expansions for 128 to 176 layer NAND devices. We also see technology ramps to 192 and above increasing during the year. We expect similar strong demand from several DRAM customer expansions, which we also believe will remain at elevated levels through the year. The strength in DRAM memory this year is being driven by the positive…

[Operator Instructions]. We'll take our first question from Craig Ellis with B. Riley Securities.

Congratulations on the very strong performance in the quarter and the outlook, guys. I wanted to start just understanding a little bit more about panel litho, really a 2-part question. I believe there's $100 million in backlog there. And if you could provide any color on the pacing of how that backlog might ship through '22 and '23, it would be helpful. And then Steve, with the commentary on gross margin, in the near term being impacted by rev rec of that product in a 53% to 55% range. The question is, is that impact something that's in the initial part of the manufacturing ramp? Or is that something that would persist through the period where we have the $100 million in backlog.

So Craig, I'll answer that one first. Yes. So I think we're going to see the manufacturing impact throughout the year. I mean, we're not shipping a lot of systems, we're going to ship only several couple of systems each quarter. And so that $100 million, as we said, go through 2022 and through 2023, I would say, maybe a little less than half of it going this year and then going into 2023, and I think some of it might be driven into 2024 now. The margin thing, as we ramp, I think, is going to be a kind of a full year event in 2022, I mean we obviously some efficiencies as they get better at building the systems as well as that's the manufacturing side of it as well as we continue to obviously work on cost downs from the engineering side and quantity buys and things like that as we grow. So I think it's going to be for the pretty good impact throughout 2022, and then you'll see improving in 2023, the impact of the litho business on our business.

Got it. And then combining that with a longer-term question related to the target model, and I'm not sure if this is better for you or for Mike. But with the target models, $1 billion, $1.2 billion and $1.4 billion points. Were those anchored either in points in time or specific levels of WFE? How should we think about the way the executive team and the broader Onto team is looking at some of the underlying drivers to attaining those different levels and over which time period?

Yes. So Craig, what we look at is pretty conservative estimates for WFE. So we look at industry growth and we consider growth as well as potential contractions. But the bulk of the model is based on the tailwinds that we can create through SAM expansion, through new product introductions, through some of the solutions that we have either recently introduced or in the pipeline, where we know where the customers demand drivers are and what their needs will be. So our model is really a combination of the market, but mostly what we're trying to drive and have a little bit more control of, if that makes sense. And let if you want to look at timing, we don't we don't have a set time, but you could guess that based on the last models, and we achieved that in this relatively quickly in this industry kind of 5-year time frame would be a reasonable 1 plus or minus on either side, more to the play.

Yes. Well, certainly, the annualized level of the first quarter's earnings guide is making very robust progress towards the $1 billion model. So good for you. But clearly, there are some gives and takes with gross margin based on some of the things that Steve said about panel litho. Okay. Very helpful, guys. I appreciate it. And congratulations again, I'll hop back in the queue.

We'll take our next question from Quinn Bolton with Needham.

Let me echo my congratulations on the results and outlook. I guess, in '21, you saw a number of product lines growing at rates well above the WFE industry, and it looks like you guys expect to do that again in 2022. Wondering if you might rank order for us or if not rank order, just give us your thoughts on which segments of the business do you think will be the fastest growing in 2022? I mean it sounds like you've got good tailwinds in litho, you've got good tailwinds in advanced packaging, but also in metrology. So kind of hitting on a lot of cylinders. So how would you rank the growth drivers in '22?

So Quinn, from a percentage basis, obviously, litho would have -- would be the top because it's starting from such a small base. So I'm going to put that to the side. From the core products, the metrology, the advanced node metrology products, we think, are going to have the strongest demand in support of the very strong demand we're seeing in the market. And the share gain opportunities we see with some of the new products and the traction we see with the solution approach we're taking with the hybrid metrology, leveraging the AI to frac software. Not too far behind that, we see real strong demand for Dragonfly in the advanced packaging and the advanced primarily to support some of the initiatives that I mentioned on the call for a much, much smaller interconnects, more dense interconnects, bumps starting to approach $500 million per wafer and the need for not just inspection, but metrology and also that reliability path that we can do with the Clearfind technology that we have. So there are several drivers on the Dragonfly platform, including the CIS, which we've seen some really nice traction in the last 2 quarters. So Dragonfly would probably be the -- an advanced packaging will probably be the next. Then third would be the compound semi, that's going to bring in our overlay metrology as well as our inspection and software. And that's a much smaller market. But from a growth perspective, the traction has been pretty robust in the last, I'd say, 4 quarters, maybe even going back 6 quarters, and we expect that to continue into 2022.

Great. And then I wanted to follow up on Craig's question about gross margins. Steve, would you expect -- I mean, obviously, that litho pressure sounds like it's going to be with you for most of 2022. So would you sort of expect gross margins to trend relatively flat during the year? Or do you think growth in other product lines cost out, hopefully, lower COVID-related and logistics costs through the year that Q1 might be a trough in gross margin with modest increases in the following quarters?

Yes, it depends. So obviously, Q1, we have several litho tools if they all -- if they get accepted, that's probably -- that's obviously what's kind of the low end of my margin guidance there. Obviously, without the tools, we're up north of 55%, right? I mean it is the high end of my guidance. It's kind of the range bound we're at. So it's going to depend on how the litho tools layer in each quarter. But I would say we've been at around 55%. So is there room to be anywhere 55.5% is probably the top end. If we have a level litho throughout the year, somewhere in that -- I think we're going to be in that 53.5% to 55.5% probably all year if the litho is evenly spread. And the concern will be, obviously, if it gets lumpy, it will have a different more of an effect.

And we'll take our next question from Brian Chin with Stifel.

Congratulations on the nice results and execution in the quarter and thanks for letting us ask a few questions. Maybe just fine-tuning maybe the question or 2 that was just asked. Mike and Steve, why don't you get beyond the revenue recognition acceptances and maybe that happens in Q1 for a customer to maybe happens in Q2. But from there out, it should be pretty much your revenue against sort of your linear shipments. Is that a fair way to put place that dynamic?

Yes. That's for sure. Yes.

Okay. Great. And then again, looping back on the substrate opportunity, it sounds like there is some room over the next, say, 12 to 18 months to drive lithium margins up. But are you more focused on wrapping higher-margin Firefly inspection and software around the litho tools replacing the customers? Is that really the bigger focus, and that will obviously drive a good margin point for that sort of blend?

I wouldn't say it's -- 1 focus is above the other, both are other focus. So we see opportunities for both. We're aggressively pursuing both areas. And we have the organization to do more than 1 thing. So nobody gets the free pass on that one.

And maybe kind of a bit of a technology question, but hybrid bonding, it certainly enables significant interconnect density. And I realize we're still a ways out from broader industry adoption. But given that systems are hitting your backlog now vis-a-vis your press release, can you describe the impact hybrid bonding will have on inspection intensity in the years ahead?

Yes, I think that's going to drive a significant shift in some of the metrology and inspection requirements. When you're talking about bonding wafers and expensive wafers together, just 1 interconnect or, let's say, coplanarity across these interconnects and when you bring them together and they don't match or they don't mesh tightly enough to make a good bond, you're destroying not just 1 chip, but multiple chips. And so the -- not just the coplanarity but also the surface roughness and the surface shape of these interconnects, is going to be critical. We're developing, we're in the process of developing technology now that will be able to address some of these future challenges as hybrid bonding moves from what we're seeing in CMOS image sensors, which are fairly larger interconnects advanced, but larger compared to what we expect to see in advanced packaging for logic and other more advanced compute devices.

We'll take our next question from Mark Miller with the Benchmark Company.

Let me add my congratulations on another very strong quarter. I'm just wondering what type of pressures are you seeing from your component suppliers in terms of pricing and how are you handling that?

Well, we've started -- I think I mentioned in my discussion about the fourth quarter margins. We are seeing some price increases being passed through. I think -- the big thing for us is we obviously -- for critical components, we have a relatively long lead purchase orders. So we've seen a little bit of that so far. We've been able to -- obviously higher revenues to offset that. But I do think that's going to continue to be a challenge for everybody for all 2022 for sure.

Are you starting -- there's a number of new fabs. I think there's at least 5 new fabs that are ramping next year. Are you starting to see any orders or you expect to see them late in the year or early next year?

For sure, we're starting to continue to see better visibility through our backlog. And I don't think we're taking significant amount of orders for 2023, but we are taking some, and we are seeing customers approaching us and starting to understand the slotting plans and wanting to reserve slots in 2023. So for sure, visibility is improving. But I wouldn't -- I think right now, the focus is really on making sure we meet all the demand that we see right now in 2022.

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

I had a couple. I guess in reference to the $100 million lithography backlog, I think you've mentioned, Steve, that just under half of it might ship this year with the balance in 2023 and '24. I'm assuming that's just the lithography systems. Could you help me understand since you're kind of packaging these with inspection or metrology and software what the total opportunity might be for that $100 million? Is the other tools adding another $100 million to that opportunity? Or is it less? Or maybe help me understand how the bundling of things impacts the $100 million of lithography backlog?

Yes. That's a great question, David. And so I'll maybe add some color or clarity. The -- we've proven use cases for panel-level fan-out. So panel level fan-out applications, we've developed a very nice integrated solution, as I described, combining the inspection, lithography and software together to solve certain inherent process issues with panel level fan-out. The X500 is going after a different panel market, the substrate market and the challenges are going to be different. So the solution doesn't directly apply, although we think several pieces of it will. But we're -- what we said in the commentary is as we begin to install these systems and understand more deeply the process and challenges, we'll have a better understanding of what other components we can bring to bear from the portfolio of technologies we have in order to provide increased productivity and yield for these customers. And for sure, that's a big need for our X500 customers. Yields are not -- they're certainly not at 90%. They're well, well below that, and they're feeling tremendous pressure to ramp and increase production capacity.

So can you characterize the $100 million, how much is for the fan-out versus the, I guess, the substrate markets? Or how are --

It's nearly all X500. So it's nearly all for the substrate market.

Okay. Okay. And then you mentioned in your prepared remarks about how you've worked hard to get into the power device markets. And I was wondering if you could just help us understand how -- as far as total revenue goes, how big is your exposure to the power markets or -- and specifically maybe the silicon carbide market. And then which product lines are the biggest drivers of your revenue and exposure to that sector?

So for power, as far as exposure goes, I think we have pretty broad exposure into the customers' manufacturing GaN silicon carbide, et cetera. They're obviously much smaller than our other customers, but with pretty high projections for growth. Our product lines that are in the -- serving those power customers. The 2 primary ones would be our Dragonfly inspection as well as our IVS or iVision overlay metrology systems. And then we bring together the software, which several power customers have also adopted. So overall, from a company standpoint, power market is a little bit smaller, and it's in the specialty devices and AP. But it is projected to be pretty decent growth on a percentage basis this year, 2022. And we do have a compelling combination of technologies, we think will give us a strong opportunity gain share in that market.

Okay. Great. Final one for me is, I think you mentioned you thought the overall WFE market would grow double digits and that I think you also mentioned that you would outperform that. So the suggestion is that whatever WFE is that your revenue should grow a bit faster. I guess I'm trying to figure out, above 10% is kind of a big range. I'm wondering what you think the WFE market will grow in 2022?

Well, we've seen estimates vary a lot, and we've seen estimates change since the last call till now. So at that point, it was 8% to 12% range. Now we've seen estimates 15%, even as high as 17%, 18%. So somewhere in that range is where -- if somebody is going to be right in their estimates, and we still feel confident we would outperform in that range.

Okay. So just to kind of -- I don't want to say pin you down, but just to understand what you just said. -- we've increased the range of WFE growth to, let's say, roughly 15%, and you think you can outperform that rate if that's where the market grows?

Correct.

[Operator Instructions] We'll take our next question from Hans Chung with D.A. Davidson.

Congratulations on strong results and outlook. So I have a couple of questions. First, I want to follow up on lithography related topic. So the $100 million, the backlog is, I think, as for the first customer, right? And then obviously, you have already clarified for third customer. So I guess my question is like how -- what kind of revenue opportunity is say, for the second and third customer going forward? Will that be -- could that be benchmarked to the $100 million type of revenue opportunity going forward? That's a good question. So within that $100 million are several customers, actually. So it's not all 1 customer. And we're really being constrained by our ability to ramp production and to ramp production capacity in a timely manner to meet the needs of the market. So we have, I'd say, 3 to 4 customers in that -- yes, maybe up to 5 customers in that bucket in that $100 million, and they all have varying levels of systems assigned to them.

Got it. So basically, it's sort of like $50 million run rate type of business going forward, right?

It depends. We've seen pretty aggressive forecast going out several years from now that depending on how well the X500 does and what share we get of the overall business could be above that. I would probably be disappointed if it was a $50 million run rate.

Got it. Got it. And the next question is, can you provide some color about the backlog exiting 2021 and also the lead time right now versus a quarter ago?

Specific to the lithography or in general?

In general?

So from a lead time perspective, it varies by product line, of course. And we have a wide range of product lines and with supply chains and demand the way it is, where obviously, lead times are pushing out. So we've been trying to get customers to issue purchase orders early enough that we can actually ensure we have the inventory and the build and the slots on hand to meet their demand. So from a rough range, I'd say, now 4 to 6 months. And for litho, it's up over -- at this point, it's almost 2 years. We're now booking for 2024.

At this time, there's no further questions in the queue. I would like to turn the conference back to Mike Sheaffer for any additional or closing remarks.

Great. Thank you, everyone, for joining us today. We know it's a busy time for earnings, and we really appreciate your time today. I'm sure we'll be catching up with some of you at the Morgan Stanley conference on March 9, and we'll be looking forward to catching up to many others throughout the quarter. With that, I'll turn the call back over to Keith to wrap it up.

Thank you. Ladies and gentlemen, this does conclude today's conference. We appreciate your participation. You may now disconnect.
