Patent ID: 8349534

Claim:
A positive resist composition comprising: a base material component (A) which exhibits increased solubility in an alkali developing solution under action of acid; an acid generator component (B) which generates acid upon exposure; and a fluorine-containing compound component (F); wherein the base material component (A) includes a polymeric compound (A1) having a structural unit (a0) represented by general formula (a0-1) shown below and a structural unit (a1) derived from an acrylate ester containing an acid dissociable, dissolution inhibiting group, and the fluorine-containing compound component (F) includes a fluorine-containing resin component having a structural unit (f1) represented by general formula (f1-0) 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 2 represents a divalent linking group; and R 3 represents a cyclic group containing —SO 2 — within the ring skeleton thereof; 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; Q 0 represents a single bond or a divalent linking group having a fluorine atom; R X0 represents an acid dissociable, dissolution inhibiting group-containing group which may contain a fluorine atom, with the provision that at least one fluorine atom is contained in formula (f1-0).
