Achieving technological breakthroughs that enable the future

Who is Cymer?

Our mission? Keep Moore’s Law—the prediction that integrated circuits (ICs) would decrease in cost and increase in performance, two-fold, in roughly two-year increments–on track. You won’t see the Cymer logo on your cell phone, tablet, or smartwatch, but chances are the microchips inside those devices were created with a Cymer ultraviolet light source. So even though there won’t be a Cymer commercial during the Super Bowl, we’re proud to deliver the photolithography light sources chipmakers and hardware manufacturers need to produce the next generation of electronics.

Our products consistently set the pace of innovation, offering a complete range of light source technologies for semiconductor manufacturing applications.


We’re part of one of the world’s largest semiconductor capital equipment companies thanks to our merger with Netherlands-based ASML in 2013.


All together we’ve donated close to $11 million since 2005, and we’re always setting and working towards new goals, pushing ourselves to improve the world for future generations.
