Inventors: Masashi Kawasaki, Hideo Ohno.
In an npn-type transistor, the emitter and collector are made of n-type transparent semiconductor material, and the base is made of p-type transparent semiconductor material. The base electrode, emitter electrode, and collector electrode are formed in their respective regions. The n-type transparent semiconductor can be doped ZnO with group III or group VII elements, while the p-type transparent semiconductor can be doped ZnO with group I or group V elements.
