Patent ID: 8034536

Claim:
A resist composition comprising a base component (A) that exhibits changed solubility in an alkali developing solution under action of acid, and an acid generator component (B) that generates acid upon exposure, wherein said base component (A) comprises a polymer compound (A1) having a structural unit (a0) represented by general formula (a0-1) shown below: wherein R 1 represents a hydrogen atom, an alkyl group of 1 to 5 carbon atoms or a fluorinated alkyl group of 1 to 5 carbon atoms, R 2 and R 3 each independently represents a hydrogen atom or an alkyl group that may include an oxygen atom at an arbitrary position, or R 2 and R 3 are bonded together to form an alkylene group, and W represents a cyclic alkylene group that may include an oxygen atom at an arbitrary position.
