High index 193 nm immersion lithography: The beginning or the end of the road
For several years, SEMATECH has invested significant effort into extending 193 nm immersion lithography by developing a set of high index materials. For high index immersion lithography (HIL) to enable 1.70NA imaging, a high index lens element with an absorbance < 0.005/cm, a fluid with an index...
