193-nm step-and-scan lithography equipment

Naoto Sano; Kazuhiro Takahashi; Hitoshi Nakano; Akiyoshi Suzuki

As the 130 nm era is approaching, requirements for lithography are becoming more and more rigorous. We have developed a 193nm scanner for below 130nm geometries capable of handling either 200 mm or 300 mm wafers. This paper describes the lithography tool performance required for printing 130nm features, focusing on a new 193nm excimer laser exposure tool developed for that age.
