Patent ID: 11429024

Abstract:
The radiation-sensitive resin composition contains: a polymer having a structural unit that includes an acid-labile group; and a compound represented by formula (1). In the formula (1), Ar1 represents a group obtained by removing (m+n+2) hydrogen atoms from an aromatic ring of an arene having 6 to 30 carbon atoms; —OH and —COO— are bonded at ortho positions to each other on a same benzene ring on Ar1; and RG represents a group represented by formula (V-1), a group represented by formula (V-2), a group including a lactone structure, a group including a cyclic carbonate structure, a group including a sultone structure, a group including a ketonic carbonyl group, a group including a thiocarbonate group, or a group including a group represented by formula (V-3), or the like.
