Abstract:
1. A semiconductor device, comprising: a gate electrode; an insulating layer on the gate electrode; a first electrode on the insulating layer; a second electrode on the insulating layer at an interval with the first electrode; an organic semiconductor layer disposed in the interval between the first electrode and the second electrode covering and contacting at least part of the first electrode and the second electrode; a first resistance layer formed on the organic semiconductor layer and having an electrical resistance lower than an electrical resistance of the organic semiconductor layer; and a second resistance layer formed at least at one of the position between the first resistance layer and the organic semiconductor layer, the position between the first electrode and the organic semiconductor layer, and the position between the second electrode and the organic semiconductor layer, wherein the second resistance layer has an electrical resistance so that carriers in the organic semiconductor layer are allowed to tunnel through the second resistance layer when a voltage of a predetermined value or more than the predetermined value is applied across the second resistance layer.
