Abstract: A radiation-sensitive composition contains a polymer having an acid-releasable group, and a compound represented by formula (1). In the formula (1), A1 represents a (m+n+2)-valent aromatic ring group. Both —OH and —COO− are bound to a common benzene ring in A1. Atom to which —OH is bound is located next to an atom to which —COO31 is bound. R1 represents a monovalent group comprising a cyclic (thio)acetal structure. m is an integer of ≥0. n is an integer of ≥0. M+ represents a monovalent organic cation.

Abstract: A radiation-sensitive resin composition includes: a compound A represented by formula (I); a resin B including a structural unit having an acid-dissociable group; a radiation-sensitive acid generator other than the compound A; and a solvent. R1 is an (m+m′)-valent organic group and comprises a cyclopropane ring skeleton, a cyclobutane ring skeleton, or both; X1 is a group represented by formula (1-1) or a group represented by formula (1-2); X2 is a group represented by formula (2-1) or a group represented by formula (2-2); Y+ is a monovalent onium cation; m is an integer of 1 to 2, and m′ is an integer of 0 to 1. * represents a bond to another group.
