Abstract
An experimental comparison of i-line lithography and deep-UV lithography was performed for 0.35 micrometers patterning of isolation level, polysilicon level, and the contact level. Both techniques used standard illumination and standard masks. The i-line process used conventional single level DNQ resists. The deep-UV work used a commercially available single level chemically amplified positive resist, with additional use of bottom-layer organic anti-reflective layers on some levels. The results highlighted the problems of pushing i-line lithography to the 0.35 micrometers regime and demonstrated the manufacturable process latitudes available with deep-UV lithography.
