Patent ID: 10514602

Abstract:
A resist composition includes a base material component and a fluorine additive component. The fluorine additive component contains a fluororesin component having a structural unit containing a base dissociable group. The base material component contains a structural unit containing an acid-decomposable group in an amount of 30 mol % or more and an amount of 10 mol % or more of a resin component having a structural unit represented by formula (a10-1): where R is a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, or a halogenated alkyl group having 1 to 5 carbon atoms, Yax1 is a single bond or a divalent linking group, Wax1 is a (nax1+1) valent aromatic hydrocarbon group, and nax1 is an integer of 1 to 3.
