Abstract:
1. A method of forming a resist pattern, comprising: forming a photosensitive layer comprising a photosensitive resin composition on a substrate, wherein the photosensitive resin composition comprises: (A) a binder polymer; (B) a photopolymerizable compound that has an ethylenically unsaturated bond; (C1) a compound represented by general formula (1) below, wherein, at least one R represents a C (C2) a 2,4,5-triarylimidazole dimer or a derivative thereof, wherein the content of the component (C1) is 0.05 to 0.8 mass parts per 100 mass parts of the total content of components (A) and (B), and the content of the component (C2) is 3 to 5 mass parts per 100 mass parts of the total content of components (A) and (B) exposing prescribed regions of the photosensitive layer to light by a direct exposure imaging technique; and developing the exposed photosensitive layer to form a resist pattern.
