Patent ID: 10324377

Abstract:
A resist composition which generates acid upon exposure and exhibits changed solubility in a developing solution under action of acid, including a base component which exhibits changed solubility in a developing solution under action of acid and an acid diffusion control agent, the base component including a structural unit represented by general formula (a0-1) shown below in which R represents H, C1-C5 alkyl group or C1-C5 halogenated alkyl group; Ya represents C; Xa represents a group which forms a divalent cyclic hydrocarbon group with Ya; Ra01 to Ra03 represents H, C1-C10 monovalent saturated chain hydrocarbon group or C3-C20 monovalent saturated cyclic hydrocarbon group; the acid diffusion control agent containing an acid which exhibits an acid dissociation constant of 1.5 or more.
