A pattern is formed by applying a first positive resist composition comprising a polymer comprising recurring units which become alkali soluble under the action of acid onto a substrate to form a first resist coating, heat treating, exposing, heat treating, developing to form a first resist pattern, applying a pattern surface coating composition comprising a hydroxyl-containing crosslinkable polymer onto the first resist pattern and crosslinking, thereby covering the first resist pattern with a crosslinked polymer film, applying a second positive resist composition thereon, heat treating, exposing, heat treating, and developing to form a second resist pattern. |
