Patent ID: 8658341

Claim:
A pattern reversal film forming composition consisting of: a polysiloxane; an additive selected from the group consisting of a pH controller, a condensation accelerator, a surfactant, a photoacid generator, and a quencher; and an organic solvent, wherein: the polysiloxane is a product of a hydrolysis and/or condensation reaction of a silane compound containing a tetraalkoxysilane of Formula (1): Si(OR 1 ) 4 (1), (where R 1 s are independently a C 1-4 alkyl) group; and an alkoxysilane of Formula (2): X n Si(OR 2 ) 4-n (2), (where: X is selected from the group consisting of a methyl group, an ethyl group, a propyl group, a vinyl group, an allyl group, a 1-propenyl group, an isopropenyl group, a propenyl, group, an ethynyl group, a phenyl group, a tolyl group, a benzyl group, and a phenylethyl group; R 2 s are independently a C 1-4 alkyl group; and n is an integer of 1 to 3; and the tetraalkoxysilane is used in a ratio of 1 to 50% by mole based on the number of moles of the whole silane compound.
