Abstract:
1. A pattern formation method for forming a micropattern, comprising: a first step of causing a first pattern-formable area at which a first pattern is to be formed on a liquid-repellent, first film that is formed on a substrate and that has a lyophilic/lyophobic variable function to be lyophilic and to reduce in thickness; a second step of forming a second film having a flat surface on the first film; and a third step of forming the first pattern at the first pattern-formable area by drying the second film, wherein the second film is formed with a coating liquid that satisfies: where surface tension is denoted by σ (N/m); film thickness is denoted by δ (m); pitch of irregularities made up of the first pattern-formable area and a first pattern-unformable area which is an area other than the first pattern-formable area is denoted by p (m); and Hamaker constant determined by the first film and the second film is denoted by a H (J).
