ABSTRACT:
This invention provides a transparent oxide semiconductor, which comprises an oxide comprising indium oxide as a main component and cerium oxide as an additive and has such properties that light-derived malfunction does not occur, there is no variation in specific resistance of a thin film caused by heating and the like, and the mobility is high, and a process for producing the same. A semiconductor thin film characterized by comprising indium oxide and cerium oxide and being crystalline and having a specific resistance of 10+1to 10+8Ωcm is used. This semiconductor thin film has no significant change in specific resistance and has high mobility. Accordingly, an element having improved switching properties can be provided by constructing a switching element using this semiconductor thin film.
