Abstract:
1. A resist composition for immersion exposure, comprising a base component (A) that exhibits changed solubility in an alkali developing solution under action of acid, an acid generator component (B) that generates acid upon exposure, and a fluorine-containing compound (C) represented by a general formula (c-1-3) or (c-1-4) shown below: wherein each R independently represents a hydrogen atom, a lower alkyl group or a halogenated lower alkyl group; X represents a linear or branched aliphatic hydrocarbon group, a monocycloalkane having 2 hydrogen atoms removed therefrom, adamantane having 2 hydrogen atoms removed therefrom, isobornane having 2 hydrogen atoms removed therefrom, tricyclodecane having 2 hydrogen atoms removed therefrom or tetracyclododecane having 2 hydrogen atoms removed therefrom, a divalent aromatic hydrocarbon group, —O—, —C(═O)—, —C(═O)—O—, a carbonate bond (—O—C(═O)—O—), —NH—, —NR 04 —, wherein R 04 represents an alkyl group, —NH—C(═O)—, a combination of a linear or branched aliphatic hydrocarbon group or a divalent aromatic hydrocarbon group with —C(═O)—O—, or a combination of a linear, branched or cyclic aliphatic hydrocarbon group or a divalent aromatic hydrocarbon group with any of —O—, —C(═O)—, a carbonate bond (—O—C(═O)—O—), —NH—, —NR 04 — wherein R 04 represents an alkyl group, —NH—C(═O)—, A aryl represents an aromatic cyclic group which may have a substituent; X 01 represents a single bond or a divalent linkage group; and each R 2 independently represents a linear or branched fluorinated hydrocarbon group having no substituent.
