Onto Innovation does not design the AI chip. It builds the eyes, rulers and feedback loops that help factories make those chips without wasting a fortune.
The company behind the machines that build almost every chip you own - and the atomic-scale materials engineering that keeps Moore's Law alive.

John Kibarian is the co-founder, President, and CEO of PDF Solutions (NASDAQ: PDFS), a Santa Clara-based semiconductor analytics company he has helmed for over 35 years. Armed with a Ph.D. in Computer Engineering from Carnegie Mellon, Kibarian started building yield-improvement algorithms while still a researcher at SEMATECH - then turned those algorithms into a company. Today PDF Solutions generates $219 million in annual revenue helping chipmakers, test facilities, and battery manufacturers squeeze more quality out of every wafer, with flagship products like the Exensio Analytics Platform and the Sapience Manufacturing Hub driving AI-powered collaboration across global semiconductor supply chains.
