Abstract :
Vacuum ultraviolet (VUV) lithography using the F/sub 2/ excimer laser (157 nm) has been proposed as the most promising candidates for 100-70 nm rule device. We have investigated the transparency and photochemical reaction of well-known polymers and resists in VUV region. In this study, we report the F/sub 2/ excimer laser exposure characteristics of resists consisting of various polymers for KrF and ArF resists.
