Abstract:
1. A resist composition comprising: a base component (A) which exhibits changed solubility in an alkali developing solution under action of an acid; an acid generator component (B) which generates an acid upon exposure; and an organic solvent (S), wherein the base component (A) comprises a polymeric compound (A1) which contains a structural unit (a0) represented by the general formula (a0-1) shown below: [Chemical Formula 1] (in the formula, R 1 represents a hydrogen atom, an alkyl group of 1 to 5 carbon atoms, or a halogenated alkyl group of 1 to 5 carbon atoms; R 2 represents a bivalent linking group; and R 3 represents a cyclic group which has —SO 2 — within the ring skeleton), and the organic solvent (S) comprises a cyclic ketone having a 5 to 7-membered ring, an ether represented by the general formula (S-1) shown below, or a mixture of the cyclic ketone having 5 to 7-membered ring and the ether represented by the general formula (S-1): [Chemical Formula 2] (in the formula, R 4 represents an alkyl group of 1 to 5 carbon atoms; R 5 represents an alkyl group of 1 to 3 carbon atoms; and n represents an integer of 0 to 2).
