Abstract
In an embodiment, a transistor device includes: a support layer having a first major surface and a second major surface opposing the first major surface; a source contact arranged on the first major surface of the support layer; a drain contact arranged on the second major surface of the support layer; and a gate electrode arranged in a first trench formed in the first major surface of the support layer. The first trench has a base and a side wall extending from the base to the first major surface. The drain contact is arranged under the base of the first trench. A region with gate-controlled conductivity is formed between the source contact and the drain contact. The region with gate-controlled conductivity is formed in an organic semiconductor layer.
