Patent ID: 8012669

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 exposure, said acid-generator component (B) comprising an acid generator (B1) consisting of a compound represented by any one of general formulae (b1-2), (b1-1-1), (b1-1-2), (b1-1-3), (b1-1-4), (b1-1-5) and (b1-2-3) shown below, and said resist composition further comprising an organic compound (C) which generates an acid exhibiting a weaker acid strength than the acid generated from said acid generator (B1) upon exposure wherein R X represents an aliphatic group which may have a substituent exclusive of a nitrogen atom; R 1 represents an alkylene group; Y 1 represents a fluorinated alkylene group of 1 to 4 carbon atoms which may have a substituent, with the proviso that the carbon atom adjacent to the sulfur atom within the —SO 3 − group has a fluorine atom bonded thereto; and A + represents an organic cation; wherein Q″ represents an alkylene group of 1 to 5 carbon atoms, —O—, —S—, —O—R 94 — or —S—R 95 —, wherein each of R 94 and R 95 independently represents an alkylene group of 1 to 5 carbon atoms, provided that Q″ does not represent an alkylene group of 1 to 5 carbon atoms in formula (b1-1-1); A + represents an organic cation; p represents an integer of 1 to 3; each of m1 to m5 independently represents 0 or 1; each of v1 to v5 independently represents an integer of 0 to 3; each of w1 to w5 independently represents an integer of 0 to 3; and R 7 represents a substituent; and wherein A + represents an organic cation; p represents an integer of 1 to 3; q3 represents an integer of 1 to 12; r2 represents an integer of 0 to 3; and R 7 ′ represents a substituent.
