Patent ID: 8883396

Claim:
A resist composition comprising: a base component (A) which generates an acid upon exposure and exhibits changed solubility in a developing solution by the action of acid and an organic solvent, wherein the base component (A) contains a copolymer (A1) having a structural unit (a0) containing a group represented by general formula (a0-2), an acid-generating moiety which generates an acid upon exposure, a structural unit (a11) containing an acid-decomposable group which exhibits increased polarity by the action of acid and contains a polycyclic group, and a structural unit (a12) containing an acid-decomposable group which exhibits increased polarity by the action of acid and contains a monocyclic group, wherein Q 2 represents a single bond or a divalent linking group; A − represents an organic group containing an anion; M m+ represents an m-valent organic cation; and m represents an integer of 1 to 3, provided that M m+ has only one aromatic ring or has no aromatic ring.
