PDF Solutions is a Santa Clara semiconductor analytics company that turns the firehose of chip-manufacturing and test data into decisions. Its Exensio platform connects fabs, foundries, OSATs and fabless designers, normalizing data across silos so customers can ramp yield faster, catch defects earlier and run AI/ML models on the factory floor. Founded in 1991 and public since 2001 (Nasdaq: PDFS), it serves 130+ semiconductor companies including TSMC, Intel, Qualcomm, Analog Devices and DENSO.
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.
