  • Patent number: 7998372
    Abstract: Disclosed is a semiconductor thin film which can be formed at a relatively low temperature even on a flexible resin substrate. Since the semiconductor thin film is stable to visible light and has high device characteristics such as transistor characteristics, in the case where the semiconductor thin film is used as a switching device for driving a display, even when overlapped with a pixel part, the luminance of a display panel does not deteriorate. Specifically, a transparent semiconductor thin film 40 is produced by forming an amorphous film containing zinc oxide and indium oxide and then oxidizing the film so that the resulting film has a carrier density of 10+17 cm?3 or less, a Hall mobility of 2 cm2/V·sec or higher, and an energy band gap of 2.4 EV or more.
