Patent ID: 8574812

Claim:
A resist composition comprising (A1) a resin having a structural unit represented by the formula (I), (A2) a resin being insoluble or poorly soluble in alkali aqueous solution, but becoming soluble in an alkali aqueous solution by the action of an acid and (B) an acid generator represented by the formula (II), wherein R 1 represents a hydrogen atom or a methyl group; A 1 represents a C 1 to C 6 alkanediyl group; R 2 represents a C 1 to C 10 hydrocarbon group having a fluorine atom wherein Q 1 and Q 2 independently represent a fluorine atom or a C 1 to C 6 perfluoroalkyl group; L 1 represents *—CO—O-L a - or *—CH 2 —O-L b -, * represents a bond to —CQ 1 Q 2 , L a and L b independently represent a C 1 to C 15 divalent saturated hydrocarbon group, and one or more —CH 2 — contained in the divalent hydrocarbon group may be replaced by —O— or —CO—; ring W 1 represents a C 2 to C 36 heterocyclic ring; Z + represents an organic cation.
