Claim:
1. An oxide semiconductor film comprising indium (In), cerium (Ce), zinc (Zn), doping metal element (M) and oxygen (O) elements, a molar ratio of In, Ce, and Zn as In:Ce:Zn is in a range of 2:(0.5 to 2):1, a carrier density of about 10 12 cm −3 to about 10 20 cm −3 , and a carrier mobility of about 5.0 cm 2 V −1 s −1 to about 46.3 cm 2 V −1 s −1 , and the oxide semiconductor film is an n-type semiconductor.
