A resist processing method having the steps of: (1) forming a first resist film by applying a first resist composition comprising: a resin (A) having an acid-labile group, being insoluble or poorly soluble in alkali aqueous solution, and being rendered soluble in alkali aqueous solution through the action of an acid, a photo acid generator (B) and a cross-linking agent (C) onto a substrate and drying; (2) prebaking the first resist film; (3) exposing to a whole surface of the first resist film, and then exposing the first resist film through a mask; (4) post-exposure baking of the first resist film; (5) developing with a first alkali developer to obtain a first resist pattern; (6) hard-baking the first resist pattern, (7) obtaining a second resist film by applying a second resist composition onto the first resist pattern, and then drying; (8) pre baking the second resist film; (9) exposing the second resist film through a mask; (10) post-exposure baking the second resist film; and (11) developing with a second alkali developer to obtain a second resist pattern.
