Patent ID: 8017431

Claim:
A method for manufacturing a thin film transistor comprising the steps of: (1) coating a solution containing an organic semiconductor material on a water-repellent surface of a water-repellent stamp substrate; (2) drying the thus coated organic semiconductor material-containing solution on the water-repellent surface to crystallize the organic semiconductor material in contact with the water-repellent surface, thereby forming a semiconductor layer; (3) thermally treating said semiconductor layer formed on said stamp substrate; and (4) pressing said stamp substrate at a side, in which the thermally treated organic semiconductor layer is formed, against a surface of a substrate to be transferred so that said organic semiconductor layer is transferred to the surface of said substrate to be transferred, wherein the substrate to be transferred is included in the thin film transistor, and wherein the organic semiconductor layer forms a channel layer of the thin film transistor.
