摘要： An oxide semiconductor target of a ZTO (zinc tin complex oxide) type oxide semiconductor material of an appropriate (Zn/(Zn+Sn)) composition having high mobility and threshold potential stability and with less restriction in view of the cost and the resource and with less restriction in view of the process, and an oxide semiconductor device using the same, in which a sintered Zn tin complex oxide with a (Zn/(Zn+Sn)) composition of 0.6 to 0.8 is used as a target, the resistivity of the target itself is at a high resistance of 1 Ωcm or higher and, further, the total concentration of impurities is controlled to 100 ppm or less.
