ABSTRACT:
To a resist composition comprising a polymer which changes its alkali solubility under the action of an acid as a base resin, is added a copolymer comprising recurring units containing amino and recurring units containing α-trifluoromethylhydroxy as an additive. The composition is suited for immersion lithography.
