Abstract:
The present invention provides a sulfonium salt capable of providing a resist composition having few defects in photolithography where a high energy beam is used as a light source, and excellent in lithography performance by controlling acid diffusion. The present invention was accomplished by a sulfonium salt including an anion and a cation, the cation having a partial structure represented by the following general formula (1), except for a sulfonium salt having a cation represented by the following general formula (1′),

Claim (Index 11):
The resist composition according to  claim 9 , wherein the component (B) is a polymer comprising a repeating unit represented by the following general formula (6) and a repeating unit represented by the following general formula (7), wherein, R A  represents any of a hydrogen atom, a fluorine atom, a methyl group, or a trifluoromethyl group; Z A  represents any of a single bond, a phenylene group, a naphthylene group, or a (main chain) \u2014C(\u2550O)\u2014O\u2014Z\u2032\u2014; Z\u2032 represents a linear, a branched, or a cyclic alkylene group having 1 to 10 carbon atoms optionally containing any of a hydroxy group, an ether bond, an ester bond, or a lactone ring, a phenylene group, or a naphthylene group; X A  represents an acid labile group; and Y A  represents a hydrogen atom, or a polar group having one or more structures selected from a hydroxy group, a cyano group, a carbonyl group, a carboxyl group, an ether bond, an ester bond, a sulfonic ester bond, a carbonate bond, a lactone ring, a sultone ring, and a carboxylic acid anhydride.
