Patent ID: 8709699

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 optionally has one or more halogen 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 a C 1 to C 17 divalent saturated hydrocarbon group, one or more —CH 2 — contained in the saturated hydrocarbon group may be replaced by —O— or —CO—; ring W represents a C 3 to C 36 alicyclic hydrocarbon group, one or more —CH 2 — contained in the alicyclic hydrocarbon group may be replaced by —O—, —S—, —CO— or —SO 2 —, one or more hydrogen atom contained in the alicyclic hydrocarbon group may be replaced with a hydroxy group, a C 1 to C 12 alkyl group, a C 1 to C 12 alkoxy group, a C 3 to C 12 alicyclic hydrocarbon group or a C 6 to C 10 aromatic hydrocarbon group; R f1 and R f2 in each occurrence independently represent a fluorine atom or a C 1 to C 6 fluorinated alkyl group; n represents an integer of 1 to 10; and Z + represents an organic cation.
