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.Type: GrantFiled: November 16, 2006Date of Patent: August 16, 2011Assignee: Idemitsu Kosan Co., Ltd.Inventors: Koki Yano, Kazuyoshi Inoue, Nobuo Tanaka, Tokie Tanaka, legal representative
