Patent ID: 7550254

Claim:
A process for generating a resist image on a substrate, comprising the steps of: (a) coating a substrate with a film of a lithographic photoresist composition comprising a radiation-sensitive acid generator and a fluorinated silsesquioxane polymer comprised of monomer units having the structure (I) wherein: R 1 , R 2 , R 3 and R 4 are independently selected from the group consisting of substituents having the structure of formula -(Q) n -CR 7 R 8 R 9 ; n is zero or 1; Q is selected from the group consisting of arylene, substituted arylene, and C 1 -C 4 alkylene optionally substituted with at least one nonhydrogen substituent selected from linear or branched alkyl and fluoroalkyl; R 7 is hydrogen, linear or branched alkyl, or fluoroalkyl; R 8 is linear or branched fluoroalkyl; and R 9 is OH, COOH or an acid-cleavable moiety; (b) exposing the film selectively to a predetermined pattern of deep ultraviolet radiation so as to form a latent, patterned image in the film; and (c) developing the latent image with a developer.
