Patent ID: 8221956

Claim:
A resist composition for immersion exposure comprising: a fluorine-containing polymeric compound (F) comprising a structural unit (f1) represented by general formula (f1-1) or (f1-2) shown below and a structural unit (f2) represented by general formula (f2-1) shown below; a base component (A) that exhibits changed solubility in an alkali developing solution under the action of acid; and an acid generator component (B) that generates acid upon exposure: wherein each R independently represents a hydrogen atom, a lower alkyl group or a halogenated lower alkyl group; X represents a divalent organic group; A aryl represents a divalent aromatic cyclic group which may have a substituent; X 01 represents a single bond or a divalent linking group; and each R 2 independently represents an organic group having a fluorine atom; wherein R represents a hydrogen atom, a lower alkyl group or a halogenated lower alkyl group; and W is a group represented by any one of general formulas (w-1) to (w-4): wherein R 21 represents an alkyl group of 2 or more carbon atoms; R 22 and R 23 are bonded to each other to form an aliphatic monocyclic group of 7 or more carbon atoms; R 24 represents a branched alkyl group of 3 or more carbon atoms; R 25 and R 26 are bonded to each other to form an aliphatic cyclic group; R 27 represents an acid dissociable, dissolution inhibiting group; R 28 represents a divalent linking group; R 29 represents a linear or branched alkyl group or an aliphatic cyclic group; n represents an integer of 0 to 3; R 30 and R 30′ each independently represent a linear or branched alkyl group or a hydrogen atom; and R 29 and R 30 may be bonded to each other to form an aliphatic cyclic group.
