About Onto Innovation
Onto Innovation makes process control equipment for semiconductor manufacturing. Chipmakers use its inspection and metrology systems to find defects and verify measurements as chips move through production, catching problems before they become scrapped wafers.
Its tools are busiest where AI chips are made. Dragonfly Inspection and Atlas Metrology are workhorses in advanced packaging, the step where AI accelerators and high-bandwidth memory are assembled, while AI-Powered Overlay improves measurement accuracy and JetStep Lithography supports packaging production.
Founded in 2019 and headquartered in Wilmington, Massachusetts, Onto Innovation trades on the NYSE and employs about 1,600 people under CEO Michael Plisinski.
Onto Innovation in the AI buildout
Onto Innovation sits in the Chip Equipment & Foundries layer, selling the inspection and metrology tools that advanced packaging lines depend on. AI accelerators and high-bandwidth memory are assembled with 2.5D packaging techniques that demand exactly this process control, so its growth is tied to HBM and packaging capacity expansion, which is currently driven almost entirely by AI demand. Supercycle scores it 70 out of 100.
ONTO is tracked in Chip Equipment & Foundries, rated Core on the AI Exposure leaderboard.
