Patent ID: 7488568

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 acid upon irradiation, said acid-generator component (B) comprising an acid generator (B1) comprised of a compound represented by general formula (b1-8) shown below or an acid generator (B1′) comprised of a compound represented by general formula (b1-9) shown below: wherein R 401 represents an acid dissociable, dissolution inhibiting group; R 41 to R 43 each independently represents a halogen atom, a halogenated alkyl group, an alkyl group, an acetyl group, an alkoxy group, a carboxy group or a hydroxyalkyl group; Q represents a divalent linking group or a single bond; n 0 represents an integer of 1 to 3, and n 1 to n 3 each independently represents an integer of 0 to 3, with the proviso that n 0 +n 1 is 5 or less; and X − represents an anion; wherein R 41 to R 43 each independently represents a halogen atom, a halogenated alkyl group, an alkyl group, an acetyl group, an alkoxy group, a carboxy group or a hydroxyalkyl group; R 402 and R 403 each independently represents a hydrogen atom, an alkyl group or a halogenated alkyl group; R 404 represents an alkyl group or a halogenated alkyl group, wherein R 403 and R 404 may be bonded to each other to form a ring structure; n 0 represents an integer of 1 to 3, and n 1 to n 3 each independently represents an integer of 0 to 3, with the proviso that n 0 +n 1 is 5 or less; and X − represents an anion.
