ON Semiconductor


ON Semiconductor is a world class IDM, driving innovations in energy efficient power solutions, intelligent Sensing and advanced analog interfacing.

The Custom Foundry Services group offers the ON Semiconductor portfolio of CMOS, high performance mixed-signal and high-voltage (BCD and Bipolar) processes used in Industrial, Automotive, Medical, Communications, Consumer, … markets to the design teams in fables companies, design houses and system houses. Additionally you can benefit from the existing ON Semiconductor supply chain.

We develop, on your request, in-house the required services for your IC, covering from wafer delivery up to finished IC’s. We provide in-house qualification, testing, failure analysis etc. We have everything in house for developing your high quality and reliable IC and bring it to the market

Operating a responsive, reliable, world-class supply chain and quality program, and a network of manufacturing facilities, ON Semiconductor Custom Foundry(SM) Services also provide unrivaled pre- and post-tape out services, which include, ESD, latch-up and high temperature characterization, die stitching, planarized passivation, full turn-key from GDS2-entry to qualified finished goods supply, AEC-Q100 qualifications, Radiation Hard and Rad Tolerant design features, Failure Analysis etc.



Global presence ensures accurate and responsive communications between our design partners and customers with the wafer factories in the USA (E.g. Pocatello, Idaho and Gresham, Oregon) and Europe (Oudenaarde, Belgium)
