Patent ID: 10606174

Abstract:
A resist composition including a polymeric compound having a structural unit derived from a compound represented by general formula (a0-1), an onium salt having an anion moiety with a specific structure, and a photodecomposable base which is decomposed upon exposure and then loses the ability of controlling of acid diffusion. In formula (a0-1), Rax0 represents a polymerizable group-containing group; Wax0 represents an aromatic hydrocarbon group having a valency of (nax0+1), provided that Rax0 and Wax0 may together form a condensed ring structure; nax0 represents an integer of 1 to 3; Yax01 represents a carbonyl group or a single bond; Rax01 represents a hydrogen atom or a hydrocarbon group which may have a substituent.
