What is the expected growth rate for Onto Innovation's DRAM revenue in the second half of 2021 compared to the first half of 2021 
ut of future discussions until we have greater clarity.
So, clearly the demand for semiconductor technology is strong and broad-based. The increasing number of connected smart devices drives both chip volume and data center growth to support explosion in data being generated by each device and enable greater remote work life experiences. These data centers are becoming digital gold mines and they are increasing the demand for high-performance compute engines to mine that data and transform it into valuable information. The value of this information to the consumer then drives higher product adoption, thus creating a virtuous cycle.
Onto Innovation sits at the center of this virtuous cycle, providing comprehensive process solutions to challenging metrology problems from 3D transistor formations to 3D and heterogeneous packaging, which is a key enabler for future product innovations. So that point in the second quarter, we project the strongest growth to come from advanced packaging and specialty customers. We see expansions from 5G and packaging customers leading that growth. We expect DRAM revenue to increase for the fourth straight quarter and NAND revenue to hold steady, while logic revenue declines following a 2x surge from the first quarter.
In summary, we see solid growth within our existing markets and we're making great progress expanding into new markets such as the planar films and the CMOS image sensing market. In addition, we're beginning to realize revenue synergies through our broader sales channels, for example, we currently expect to add over eight new customers for our optical metrology suite by the end of 2021 simply by leveraging our existing inspection channels into the specialty device markets. Likewise, we're beginning to see the potential for revenue synergies with our overlay products and inspection systems outside of the compound semiconductor markets. Each of these dynamics, many in the early stages of realization contribute to our positive outlook for next year and into 2022.
It's certainly an exciting time to be a part of Onto Innovation, and I want to thank the entire team for their continued dedication to our customers' success. I also want to call attention to our First Annual Corporate Social Responsibility Report for 2020, which is available on our website. The report outlines several of Onto Innovation's ESG initiatives and our commitment to have a positive impact on our communities, the environment both local and global and our dedicated employees.
Thank you. And Connor, we can now open the call for questions.

Thank you. [Operator Instructions] And we will take our first question. This will come from Craig Ellis with B Riley Securities.

Thanks for taking the question. And guys, congratulations on the strong execution in the first quarter. Mike, I wanted to start just by following up on one of the points you made early in your remarks and then came back to, on your conclusion you talked about an even stronger second half. And I was wondering in the past you've sometimes characterized year-on-year growth over a period encompassing two quarters like you've done with the first quarter of this year. Any color on magnitude of increase in the second half either half on half or year-on-year? And if you look at the second half, would you expect revenues to rise sequentially through the year, or for different dynamics that you see, which you expect things to potentially peak in the third quarter, so that's first question.
Michael Plisinski -- Chief Executive Officer
So what we see right now, we believe revenues will rise sequentially throughout the remainder of the year. So we expect Q4 to be stronger than Q3, and we expect Q3 to be stronger than Q2. So that's what we're seeing right now. Contributing to that is, not just general market dynamics, but also the expansions that we're making into some new markets for us, where we're seeing like I mentioned earlier in the planar films, additional adoption there. We've also men
