Patent ID: 8394569

Claim:
A resist composition for immersion lithography comprising: a resin component (A) which exhibits changed alkali solubility under the action of acid; and an acid generator component (B) which generates acid on exposure, wherein the resin component (A) includes a resin (A1), which is a homopolymer of a structural unit (a) which is represented by the following general formula (a) and contains a fluorine atom and no acid-dissociable group, and a resin (A2) containing a structural unit (a′) derived from an acrylic acid and no fluorine atom, the mass ratio of the resin (A1) and resin (A2) is 0.1-20:99.9:80, and the resin (A1) contains a fluorinated hydroxyalkyl group, wherein R 20 represents a hydrogen atom, a halogen atom, an alkyl group, or a halogenated alkyl group; and X represents a monovalent organic group comprising the fluorinated hydroxyalkyl group.
