Cymer is an independently operated business within the ASML group that develops, manufactures and services deep-ultraviolet (DUV) light sources

ASML acquired Cymer in 2013 to accelerate the development of extreme ultraviolet (EUV) semiconductor lithography. Based in San Diego, California, Cymer was founded in 1986 by two college friends Robert Akins and Richard Sandstrom to develop laser and lithography light source technology for the semiconductor industry.

Cymer products

Cymer's product portfolio includes excimer lasers using argon fluoride (ArF) or krypton fluoride (KrF) gases to generate light in the deep-ultraviolet spectrum.

These lasers generate the light that photolithography scanners use to image patterns on silicon wafers. Research, development and manufacturing of DUV light sources is centered in San Diego.
