Patent ID: 8323869

Claim:
A positive resist composition comprising a base component (A) which exhibits changed solubility in an alkali developing solution under the action of acid, an acid-generator component (B) which generates acid upon exposure and a fluorine-containing compound component (F), the base component (A) comprising a polymeric compound (A1) comprised of 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) comprising a fluorine-containing polymeric compound (F1) comprised of a structural unit (f1) containing a base dissociable group: 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 an —SO 2 — group within the ring skeleton thereof.
