Patent ID: 7713679

Claim:
A resist composition comprising 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 X represents a hydrocarbon group which may contain a substituent group; Q 1 represents an alkylene group of 1 to 12 carbon atoms which may contain a substituent group, or a single bond; n represents an integer of 0 or 1; Y 1 represents an alkylene group of 1 to 4 carbon atoms or a fluorinated alkylene group of 1 to 4 carbon atoms; and A + represents an organic cation which contains a nitrogen atom), and said A + in the general formula (B1-1) comprises a group represented by a general formula (I) shown below: (in the formula, W 1 represents an oxygen atom or a sulfur atom; Q 2 represents an alkylene group or a single bond; and R 7 and R 8 each independently represents a hydrogen atom, an alkyl group which may contain a substituent group, an aliphatic cyclic group which may contain a substituent group, or an aromatic cyclic group which may contain a substituent group, wherein R 7 and R 8 may mutually be bonded to form a ring).
