The invention refers to a method for producing an organic transistor, the method comprising steps of providing a first electrode (2) on a substrate (1), generating a source-drain insulator (3) assigned at least partially to the substrate (1) and/or at least partially to the first electrode (2), generating a second electrode (4) assigned to the source-drain insulator (3), depositing an organic semiconducting layer (5) on the first electrode (2), the second electrode (4), and the source-drain insulator (3), generating a gate insulator (6) assigned to the organic semiconducting layer (5), and providing a gate electrode (7) assigned to the gate insulator (6). Further, the invention relates to an organic transistor.
