Patent ID: 8603726

Claim:
A radiation-sensitive resin composition comprising (A) a polymer that includes a repeating unit (a1) and a fluorine atom, and (B) a photoacid generator, the repeating unit (a1) including a group shown by any of formulas (1-1) to (1-3), wherein R P represents a monovalent organic group, Z 1 represents a carbon atom, Z 2 represents a trivalent group that forms a cyclic hydrocarbon group together with Z 1 , Q 0 in the formula (1-1) individually represent a hydrogen atom or a monovalent group, provided that at least one of Q 0 represents a monovalent organic group that includes an electron-withdrawing group, Q 0 in the formula (1-3) represents a monovalent organic group that includes an electron-withdrawing group, provided that a case where all of Q 0 in the formula (1-1) represent a fluorine atom or a fluorine-substituted hydrocarbon group is excluded, and “*” indicates a bonding hand, wherein the repeating unit (a1) includes at least one electron-withdrawing group as Q 0 , the at least one electron-withdrawing group being other than a fluorine atom or a fluorine-substituted hydrocarbon group, and being bonded directly to a carbon atom at an α-position with respect to an ester group.
