FEATURES
Extreme UV Keeps Pace with Moore’s Law May 30, 2018 — For years, 193-nm immersion lithography enabled foundries to create increasingly smaller features on silicon wafers. The technique involved shining 193-nm light through a patterned surface that cast a pattern onto a blank silicon wafer. But problems arose: At 193 nm, the light is much longer than the size of the features, requiring the use of a number of different photomasks and numerous passes to create the finished pattern. That has led the semiconductor manufacturing industry to investigate...
