Abstract:
1. A resist composition comprising a base component (A) which exhibits changed solubility in a developing solution under action of acid and an acid-generator component (B) which generates acid upon exposure, the base component (A) comprising a polymeric compound (A1) comprising a structural unit (a1) containing an acid decomposable group that exhibits increased polarity by the action of acid and a structural unit (a5) represented by general formula (a5-0) shown below: wherein R 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 1 represents a sulfur atom or an oxygen atom; R 2 represents a single bond or a divalent linking group; and Y represents an aromatic hydrocarbon group or an aliphatic hydrocarbon group having a polycyclic group, provided that the aromatic hydrocarbon group or the aliphatic hydrocarbon may have a carbon atom or a hydrogen atom thereof substituted with a substituent.
