The present invention provides a semiconductor thin film which can be manufactured at a relatively low temperature even on a flexible resin substrate. As a semiconductor thin film having a low carrier concentration, a high Hall mobility and a large energy band gap, an amorphous film containing zinc oxide and tin oxide is formed to obtain 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. Then, the amorphous film is oxidized to form a transparent semiconductor thin film 40. |
