Patent ID: 8628908

Claim:
A chemically amplified resist composition comprising (A) at least one tertiary amine compound having the general formula (1), (B) at least one acid generator having the general formula (2), (C) a base resin having an acidic functional group protected with an acid labile group, which is insoluble or substantially insoluble in alkaline developer and turns soluble in alkaline developer upon deprotection of the acid labile group, and (D) an organic solvent, wherein R 1 is a C 1 -C 20 alkyl or alkenyl group or a substituted or unsubstituted C 6 -C 20 aryl or aralkyl group, which may contain a heteroatom, R 2 is a C 1 -C 10 alkyl group, R 3 is a C 1 -C 10 alkyl or alkoxy group, k is 1 or 2, and m is an integer of 0 to 5, wherein R 4 is a C 1 -C 30 alkyl, alkenyl or aralkyl group which may contain a heteroatom, or a backbone of the base resin (C), R 5 is hydrogen or trifluoromethyl, R 6 is Ar or a C 1 -C 20 alkyl or alkenyl group which may contain a heteroatom, or two R 6 may bond together to form a C 5 -C 8 ring with the sulfur atom to which they are attached, Ar is a substituted or unsubstituted C 6 -C 20 aryl group which may contain a heteroatom.
