An electron beam resist with high electron beam sensitivity can be formulated with poly(p-vinyl phenol) and the diester of dihydroxy benzophenone of o-naphthoquinone-1-diazide-5-sulfonic acid. Brominated poly(p-vinyl phenol) has enhanced cross-linking reactions under electron beam exposures, which may be used for reversed image generations with electron beam-flood UV-exposures.
