Method for manufacturing organic semiconductor film, and organic semiconductor film array

Abstract

A raw material solution containing an organic semiconductor material and a solvent is supplied onto a substrateand dried, forming an organic semiconductor film. A contact memberis used, which is provided with multiple contact facesfor contacting the raw material solution. The contact member is positioned such that the contact faces have a certain relationship with the surface of the substrate, and multiple dropletsof the raw material solution is formed on the substrate, thereby establishing a droplet-retaining state, in which the contact faces retain the respective droplets. The solvent is evaporated to form organic semiconductor films at the locations on the surface of the substrate that correspond to the multiple contact faces. The method can be performed with simple solution processes and can produce organic semiconductor films of high charge mobility.
