Patent ID: 8663899

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 2 to C 6 alkanediyl group; R 2 represents a C 1 to C 10 hydrocarbon group having a fluorine atom; wherein R b1 and R b2 independently represent a fluorine atom or a C 1 to C 6 perfluoroalkyl group; L b1 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 b1 represents a C 2 to C 36 heterocycle which has non-aromaticity; R b3 represents a hydrogen atom or a C 1 to C 12 hydrocarbon group, one or more —CH 2 — contained in the hydrocarbon group may be replaced by —O— or —CO—; R b4 in each occurrence independently represent a C 1 to C 6 hydrocarbon group, one or more —CH 2 — contained in the hydrocarbon group may be replaced by —O— or —CO—; m represents an integer of 0 to 6; and Z 1+ represents an organic cation.
