Patent ID: 8524123

Claim:
A sputtering target, comprising a sintered body of an oxide comprising at least indium, tin, and zinc and comprising a spinel structure compound of Zn 2 SnO 4 and a bixbyite structure compound of In 2 O 3 , wherein, in an X-ray diffraction (XRD), a hexagonal layered compound of In 2 O 3 (ZnO) m , wherein m is an integer of 2 to 20, has a maximum peak intensity (I/In 2 O 3 (ZnO) m ), a spinel structure compound of Zn 2 SnO 4 has a maximum peak intensity (I(Zn 2 SnO 4 )), and a bixbyite structure compound of In 2 O 3 has a maximum peak intensity (I(In 2 O 3 )), wherein the maximum peak intensity of the hexagonal layered compound of In 2 O 3 (ZnO) m , wherein m is an integer of 2 to 20, (I/In 2 O 3 (ZnO) m ), the maximum peak intensity of the spinel structure compound of Zn 2 SnO 4 (I(Zn 2 SnO 4 )), and the maximum peak intensity of the bixbyite structure compound of In 2 O 3 (I(In 2 O 3 )) have the following relationship: I(In 2 O 3 (ZnO) m )<I(Zn 2 SnO 4 ) I(In 2 O 3 (ZnO) m )<I(In 2 O 3 ) I(In 2 O 3 (ZnO) m )<Max.(I(Zn 2 SnO 4 ), I(In 2 O 3 ))÷10 wherein Max. (X,Y) indicates the larger of either X or Y.
