Patent ID: 7745097

Claim:
A resist composition, which comprises a base component (A) which exhibits changed solubility in an alkali developing solution under action of acid, and an acid generator component (B) which generates an acid upon exposure, wherein the acid generator component (B) comprises an acid generator (B1) represented by a general formula (b1-1) shown below: (wherein, R 1 represents an aryl group or alkyl group which may contain a substituent group; R 3 represents a hydrogen atom or an alkyl group; n1 represents an integer of 0 or 1, and in the case that n1 is 1, R 1 and R 3 may mutually be bonded to form a ring with a 3- to 7-membered ring structure together with the carbon atom with which R 1 is bonded and the carbon atom with which R 3 is bonded; A represents a bivalent group which forms a ring with 3- to 7-membered ring structure together with the sulfur atom with which A is bonded, and the ring may contain a substituent group; R 2 represents an aromatic group which may contain a substituent group, a linear or branched alkyl group of 1 to 10 carbon atoms which may contain a substituent group, or a linear or branched alkenyl group of 2 to 10 carbon atoms which may contain a substituent group; n represents an integer of 0; and Y 1 represents an alkylene group of 1 to 4 carbon atoms in which hydrogen atoms may be substituted with fluorine atoms).
