Patent ID: 10824073

Abstract:
A radiation-sensitive resin composition includes a first compound represented by formula (1), a first polymer comprising an acid-labile group, and a radiation-sensitive acid generator other than the first compound. The radiation-sensitive acid generator includes an onium salt compound. In the formula (1), n is 2 or 3; m is 1 or 2; Y+ represents a monovalent radiation-sensitive onium cation; and L represents a single bond or an organic group having a valency of n. L includes linking moieties each linking two of the carboxylate groups in formula (1). Number of atom(s) included in a linking moiety having a minimum number of bonds among the linking moieties is 0 to 10. In a case where L represents a single bond, n is 2, and in a case where n is 2, m is 1.
