Patent ID: 8426113

Claim:
A method comprising, (a) forming onto a substrate a film comprising: (i) a silsesquioxane polymer having a structure of Formula (I), (I) wherein, R 1 is independently selected from the group consisting of alkyls, cycloalkyls, and aryl groups; R 2 is an electron withdrawing functionality independently selected from the group consisting of bromine, chlorine, iodine, acetoxy, substituted acetoxy, thioacetoxy, benzoyl, and substituted benzoyl; p is 1, 2, or 3; and m and n represent the mole percent of each repeating unit; and (ii) a photosensitive acid generator (PAG); (b) patternwise imaging the film using an electron-beam (e-beam), wherein at least one region of the film is exposed to radiation and an acid catalyst is produced in the at least one exposed region of the film; (c) baking the imaged film; and (d) developing the baked film, wherein the developing removes unexposed base-soluble regions of the film resulting in a relief pattern on the film.
