Abstract:
1. 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 monomeric compound represented by general formula (b1-1) shown below: wherein R x represents a saturated hydrocarbon group with or without a substituent exclusive of a nitrogen atom; Q 2 represents a hetero atom-containing linkage group; Q 3 represents an ether bond (—O—), a thioether bond (—S—), an —NH— bond (the H may be replaced with a substituent), an ester bond (—C(═O)—O—), an amido bond (—C(═O)—NH—), a carbonyl group (—C(═O)—) and a carbonate bond (—O—C(═O)—O—), —R 91 —O—, —R 92 —O—C(═O)— or —C(═O)—O—-R 93 -(wherein each of R 91 to R 93 independently represents a linear or branched alkylene group); Y 1 represents an alkylene group or fluorinated alkyl group of 1 to 4 carbon atoms; and Z + represents an organic cation exclusive of an ion represented by general formula (w-1) shown below: wherein each of R 3 to R 6 independently represents a hydrogen atom or a hydrocarbon group with or without a substituent, with the proviso that at least one of R 3 to R 6 represents a hydrocarbon group; and at least two of R 3 to R 6 may be mutually bonded to form a ring.
