摘要:
In a thin film transistor, a gate insulating layer is formed on a gate electrode formed on an insulating substrate. Formed on the gate insulating layer is a semiconductor layer. Formed on the semiconductor layer are a source electrode and a drain electrode. A protective layer covers them, so that the semiconductor layer is blocked from an atmosphere. The semiconductor layer (active layer) is made of, e.g., a semiconductor containing polycrystalline ZnO to which, e.g., a group V element is added. This allows practical use of a semiconductor device which has an active layer made of zinc oxide and which includes an protective layer for blocking the active layer from an atmosphere.

To solve the foregoing problems, provided is a ZnO-based semiconductor element having an entirely novel function distinct from hitherto, using a ZnO-based semiconductor and organic matter for an active role. An organic electrode 2 is formed on a ZnO-based semiconductor 1, and an Au film 3 is formed on the organic electrode 2. An electrode formed of a multilayer metal film including a Ti film 4 and an Au film 5 is formed on the back surface of the ZnO-based semiconductor 1 so as to be opposed to the organic electrode 2. A bonding interface between the organic electrode 2 and the ZnO-based semiconductor 1 is in a pn junction-like state. Thus, rectification occurs therebetween.

A channel layer 11 formed of a transparent semiconductor such as zinc oxide ZnO. A transparent electrode is used for all of a source 12, a drain 13 and a gate 14, or a part of them. As the transparent electrode, a transparent conductive material such as conductive ZnO doped with, for example, group III elements is used. As a gate insulating layer 15, a transparent insulative material such as insulative ZnO doped with elements capable of taking a valence of one as a valence number or group V elements is used. If a substrate 16 must be transparent, for example, glass, sapphire, plastic or the like can be used as a transparent material.
