  • Patent number: 10205094
    Abstract: A raw material solution (6), in which an organic semiconductor material is dissolved in a solvent, is supplied to a substrate (1). The solvent is evaporated so that crystals of the organic semiconductor material are precipitated. Thus, an organic semiconductor thin film (7) is formed on the substrate (1). An edge forming member (2) having a contact face (2a) on one side is used and located opposite the substrate (1) so that the plane of the contact face (2a) intersects the surface of the substrate (1) at a predetermined angle. The raw material solution (6) is supplied to the substrate (1) and formed into a droplet (6a) that comes into contact with the contact face (2a).
