EUV light source development and droplet generator manufacturing
ASML San Diego designs, develops and qualifies the EUV laser-produced plasma light source and manufactures its droplet generator, the component that delivers a stream of 50,000 liquid tin droplets per second into the vacuum vessel at more than 241 km per hour. Research, development and manufacturing of ASML’s DUV light sources, the Cymer excimer lasers that use argon fluoride or krypton fluoride gases, is centered here; Cymer was founded in 1986 and ASML acquired it in 2013. Over 300 employees manufacture EUV droplet generators and Cymer DUV light sources at the site.
The team at ASML San Diego designs, develops and qualifies the EUV (extreme ultraviolet) laser-produced plasma light source, and manufactures a critical system component called the droplet generator. The droplet generator is the heartbeat of the light source, delivering a steady stream of 50,000 liquid tin droplets per second, which fly at more than 241 km per hour in a vacuum vessel.
