  • Publication number: 20180326447
    Abstract: A device for manufacturing an organic semiconductor film, including a coating member disposed to face a substrate surface while spaced therefrom for forming the film, and forming a liquid reservoir of an organic semiconductor solution between the coating member and the substrate; a supply portion that supplies the solution; and a cover portion that covers at least a crystal growth portion of the solution. The cover portion includes a guide that guides a deposit formed of an evaporated solvent of the solution to a film-unformed region of the organic semiconductor film. While the solution is supplied between the coating member and the substrate surface by the supply portion, the coating member is moved in a first direction parallel to the substrate surface in a state of being in contact with the solution, to form the film with the crystal growth portion as a starting point.
