Abstract:
1. A sputtering target comprising indium oxide and positive trivalent cerium oxide, wherein [Ce]/([In]+[Ce])=0.005 to 0.035 wherein [Ce] represents the number of the atoms of cerium per unit weight/unit mass, and [In] represents the number of the atoms of indium per unit weight/unit mass, and wherein the abundance of trivalent cerium [Ce +3 ]/([Ce +3 ]+[Ce +4 ]) is 0.01 to 0.6, wherein when its crystal peaks are observed by X-ray diffraction, the presence of peaks originating from indium oxide and cerium oxide is observed, and further when EPMA measurement is performed, the measured diameter of particles of cerium oxide dispersed in indium oxide is 5 μm or less.
