Patent ID: 8889335

Claim:
A radiation-sensitive resin composition comprising: a compound represented by a formula (I); a first polymer that serves as a base resin; and a second polymer that has a fluorine atom content higher than a fluorine atom content of the first polymer, wherein R 1 is a monovalent group that includes at least two groups of —CO—, —NH—, —S—, and —SO 2 —, the at least two groups being each identical or different, and is a group represented by a formula (a1), a group represented by a formula (a3), or both thereof, -A-(CFR) a — is —CH 2 CH 2 CF 2 CF 2 — or —CH 2 CH 2 CH 2 CF 2 CF 2 —, and M + is a monovalent cation, wherein X 1 to X 5 are each independently —CO—, —COO—, —OCO—, —O—CO—O—, —NHCO—, —CONH—, —NH—CO—O—, —O—CO—NH—, —NH—, —S—, —SO—, or —SO 2 —, R 2 is a monovalent hydrocarbon group having 1 to 30 carbon atoms, R 3 , R 5 , and R 6 are each independently a divalent hydrocarbon group having 1 to 30 carbon atoms, wherein some or all of hydrogen atoms of the monovalent hydrocarbon group represented by R 2 or the divalent hydrocarbon group represented by R 3 , R 5 , or R 6 are unsubstituted or substituted with a substituent, Z is a group that has a heterocyclic structure taken together with —(X 3 —R 5 ) p —, p is an integer from 1 to 3, and r is 0 or 1, in a case where a plurality of X 3 are present, each of the plurality of X 3 is either identical or different, and in a case where a plurality of R 5 are present, each of the plurality of R 5 is either identical or different.
