Onto Innovation was born in 2019 from the merger of Rudolph Technologies (with roots stretching back to 1940) and Nanometrics, instantly becoming a heavyweight in semiconductor process control. Headquartered in Wilmington, Massachusetts, they specialize in metrology, defect inspection, advanced packaging lithography, and factory analytics software that help chipmakers squeeze out higher yields, better quality, and faster production across the entire value chain. With thousands of patents and tools serving the world’s biggest fabs, Onto keeps the semiconductor industry humming efficiently while enabling breakthroughs in AI, EVs, and power electronics.

Onto stays refreshingly anti-woke by channeling energy into practical results like slashing carbon emissions 51% per employee, boosting renewable energy use to 41%, and hitting sustainability targets years ahead of schedule, all without rainbow-splashed campaigns that turn other tech giants into lecture halls. Their core values (Passion, Integrity, Collaboration, Results) focus squarely on customer success and real innovation, proving you can lead in cutting-edge chips without chasing performative points. Interestingly, by powering greener technologies through better process control, they deliver actual environmental wins instead of just virtue-signaling about them.
