发明名称 Method of forming resist pattern
摘要 A method of forming a resist pattern that includes: applying a positive chemically amplified resist composition to a support to form a first resist film, exposing a region on a portion of the first resist film, performing a post exposure bake treatment and then performing developing to form a first resist pattern, and applying a negative chemically amplified resist composition to the support having the first resist pattern formed thereon, thereby forming a second resist film, exposing a region of the second resist film that includes the positions in which the first resist pattern has been formed, performing a post exposure bake treatment at a bake temperature that increases the solubility of the first resist film in an alkali developing solution and decreases the solubility of the second resist film in an alkali developing solution, and then performing developing to form a resist pattern.
