About Onto Innovation

Onto Innovation Inc. is an American semiconductor capital equipment company that specializes in process control, metrology, inspection, and software solutions. The company was officially formed in late 2019 through a merger of equals between two established industry players, Nanometrics Incorporated and Rudolph Technologies. Onto Innovation's mission centers on equipping semiconductor manufacturers with the advanced tools needed to enhance device yield, boost productivity, and lower overall production costs. Its core offerings include 3D metrology, macro defect inspection, unpatterned wafer quality assessment, and specialized factory analytics software.

The company serves a global business-to-business market, primarily targeting front-end wafer fabrication plants, advanced packaging facilities, and specialty semiconductor manufacturers. Onto Innovation's solutions are critical for clients producing high-bandwidth memory, gate-all-around logic transistors, and power semiconductors. The business model relies on the direct manufacturing and sales of highly specialized capital equipment, supplemented by ongoing service contracts, component upgrades, and proprietary software licenses. Revenue generation is heavily driven by capital expenditure cycles in the broader semiconductor industry, particularly large-scale investments in artificial intelligence infrastructure and advanced device nodes.

Onto Innovation distinguishes itself through its comprehensive approach to the semiconductor value chain, offering end-to-end process control spanning from nanometer-scale transistors to micron-level die-interconnects. Key features of its technology include high-precision optical critical dimension metrology, high-speed macro defect inspection, and advanced data analysis platforms that provide actionable manufacturing insights. By integrating capabilities across both front-end fabrication and back-end packaging, the company enables chipmakers to optimize their processes for complex, next-generation architectures like chiplets and heterogeneous integration.
