LIGHT SOURCE TECHNOLOGY - Cymer

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

Laser Produced Plasma Source for NXE:3300B EUVL Symposium

In this paper a new approach to a laser-produced plasma EUV source based on a tin target is presented. A thin layer of pure tin and composite layers consisting of Sn with Si, SiO and LiF are investigated. The target composed of several thin layers produces less debris than the other targets and provides a conversion efficiency (CE) in the 13.5-nm±1% band at least comparable to the CE for the ...
