Abstract:
Disclosed is a sputtering target that can suppress the occurrence of anomalous discharge in the formation of an oxide semiconductor film by sputtering method and can continuously and stably form a film. Also disclosed is an oxide for a sputtering target that has a rare earth oxide C-type crystal structure and has a surface free from white spots (a poor appearance such as concaves and convexes formed on the surface of the sputtering target). Further disclosed is an oxide sintered compact that has a bixbyite structure and contains indium oxide, gallium oxide, and zinc oxide. The composition amounts (atomic %) of indium (In), gallium (Ga), and zinc (Zn) fall within a composition range satisfying the following formula: In/(In+Ga+Zn)
