Patent ID: 7264918

Claim:
A method for forming a resist pattern using a liquid immersion lithography process, which comprises: forming a resist film on a substrate using a resist composition; forming a protective film on the resist film; applying a liquid directly onto the protective film; selectively exposing the resist film through the liquid and the protective film; subjecting the resultant resist film to post exposure bake treatment; and subjecting the resist film to development, thus forming a resist pattern, wherein the resist composition comprises: (A) a polymer comprising (a1) alkali-soluble constitutional units each comprising an alicyclic group having both (i) a fluorine atom or a fluoroalkyl group and (ii) an alcoholic hydroxyl group, wherein the polymer changes in alkali-solubility due to the action of acid; (B) an acid generator which generates acid due to exposure to light and (C) an amine.
