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 2):
The sulfonium salt according to  claim 1 , wherein the sulfonium salt is represented by the following general formula (2), wherein, each of R 1 , R 2 , and R 3  independently represents any of a hydrogen atom, a partial structure represented by the general formula (1), a linear, a branched, or a cyclic monovalent hydrocarbon group having 1 to 20 carbon atoms optionally containing a heteroatom, or direct binding with an adjacent benzene ring; each of \u201cp1\u201d, \u201cq1\u201d, and \u201cr1\u201d independently represents an integer of 0 to 5, and when \u201cp1\u201d, \u201cq1\u201d, or \u201cr1\u201d represents 2 or more, a plurality of R 1 s, R 2 s, or R 3 s corresponding thereto may be the same or different, when p1+q1+r1 represents 2 or more, a plurality of R 1 s, R 2 s, or R 3 s may be bonded to form a ring together with a carbon atom on a benzene ring bonded thereto, and R 1  and R 2 , R 1  and R 3 , or R 2  and R 3  may be bonded to form a ring together with two benzene rings bonded thereto and a sulfur atom in the formula; one or more of R 1 , R 2 , and R 3  represent a partial structure represented by the general formula (1), \u201c*\u201d in the general formula (1) represents a bond with a benzene ring; and Z \u2212  represents a monovalent anion.
