Patent ID: 8859182

Claim:
A resist composition comprising: (A) a resin having a structural unit represented by the formula (IA); (B) an acid generator; (D) a compound represented by the formula (II); wherein R 23 represents a hydrogen atom, a halogen atom or a C 1 to C 6 alkyl group that optionally has one or more halogen atoms; R 24 and R 25 in each occurrence independently represent a hydrogen atom or a C 1 to C 24 hydrocarbon group, and R 26 to R 29 independently represent a hydrogen atom or a C 1 to C 24 hydrocarbon group, or at least two of R 24 to R 29 may be bonded together to form a C 3 to C 30 ring, one or more hydrogen atoms contained in the hydrocarbon group or the ring may be replaced by a halogen atom, a hydroxy group, a C 1 to C 12 alkyl group, a C 1 to C 12 alkoxyl group, a C 2 to C 4 acyl group or a C 2 to C 4 acyloxy group, and one or more —CH 2 — contained in the hydrocarbon group or the ring may be replaced by —CO— or —O—; n′ represents an integer of 0 to 3; wherein R 3 and R 4 in each occurrence independently represent a C 1 to C 12 hydrocarbon group, a C 1 to C 6 alkoxyl group, a C 1 to C 7 acyl group, a C 1 to C 7 acyloxy group, a C 1 to C 7 alkoxycarbonyl group, a nitro group or a halogen atom; m and n independently represent an integer of 0 to 4; and a solvent.
