Abstract
Novel photoresists containing at least about 0.2 molar ratio of a base with respect to the concentration of a photoacid generator present and their preparation are described. It has been discovered that inclusion of a sufficient amount of base counteracts the detrimental effects of photoacid generators, thus providing resists having submicron linewidth resolution.
