Patent ID: 8227170

Claim:
A resist composition comprising a base component (A) which exhibits changed solubility in an alkali developing solution under action of an acid, and an acid generator component (B) which generates an acid upon exposure, wherein the base component (A) comprises a polymeric compound (A0) containing a structural unit (a0) represented by the general formula (a0-1) shown below: (in the formula (a0-1), R 1 represents a hydrogen atom, a lower alkyl group of 1 to 5 carbon atoms, or a halogenated lower alkyl group of 1 to 5 carbon atoms; R 2 represents a bivalent linking group containing at least one kind of polar groups selected from the group consisting of —O—, —C(═O)—, —C(═O)—O—, a carbonate linkage (—O—C(═O)—O—), —S—, —S(═O) 2 —, —S(═O) 2 —O—, —NH—, —NR 04 — (wherein, R 04 represents an alkyl group or an acyl group), and —NH—C(═O)—; and R 3 represents a cyclic group containing a sulfonyl group within the ring skeleton).
