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 14):
The resist composition according to  claim 10 , wherein the component (D) is represented by the following general formula (8) or the following general formula (9), wherein, each of R 100 , R 200 , and R 300  independently represents a linear, a branched, or a cyclic monovalent hydrocarbon group having 1 to 20 carbon atoms optionally containing a heteroatom, and two or more of R 100 , R 200 , and R 300  may be bonded to form a ring together with a sulfur atom in the formula; and X a\u2212  represents an anion represented by any of the following general formula (8A), (8B), (8C) or (8D), wherein, each of R fa1 , R fb1 , R fb2 , R fc1 , R fc2 , and R fc3  independently represents a fluorine atom, or a linear, a branched, or a cyclic monovalent hydrocarbon group having 1 to 40 carbon atoms optionally containing a heteroatom; R fb1  and R fb2 , and R fc1  and R fc2  may be bonded to form a ring together with a carbon atom bonded thereto and an atom therebetween; and R fd  represents a linear, a branched, or a cyclic monovalent hydrocarbon group having 1 to 40 carbon atoms optionally containing a heteroatom, wherein, each of R 400  and R 500  independently represents a linear, a branched, or a cyclic monovalent hydrocarbon group having 1 to 30 carbon atoms optionally containing a heteroatom; R 600  represents a linear, a branched, or a cyclic divalent hydrocarbon group having 1 to 30 carbon atoms optionally containing a heteroatom; two or more of R 400 , R 500 , and R 600  may be bonded to form a ring together with a sulfur atom in the formula; L 1  represents a single bond, an ether bond, or a linear, a branched, or a cyclic divalent hydrocarbon group having 1 to 20 carbon atoms optionally containing a heteroatom; each of X a7 , X b7 , X a8 , and X b8  independently represents any of a hydrogen atom, a fluorine atom, or a trifluoromethyl group; one or more of X a7 , X b7 , X a8 , and X b8  represent a fluorine atom or a trifluoromethyl group.
