Patent ID: 8735047

Claim:
A resist composition comprising a resin having a structural unit represented by the formula (I), 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 not including the structural unit represented by the formula (I), and 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; A 13 represents a C 1 to C 18 divalent aliphatic hydrocarbon group that has one or more fluorine atoms; X 12 represents *-CO—O— or *-O—CO—; * represents a bond to A 13 ; A 14 represents a C 1 to C 17 aliphatic hydrocarbon group that optionally has one or more halogen atoms; 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.
