Abstract
Provided is an Sb—Te base alloy sinter sputtering target having Sb and Te as its primary component and comprising a structure in which Sb—Te base alloy particles are surrounded by fine carbon or boron particles; wherein, if the mean diameter of the Sb—Te base alloy particles is X and the particle size of carbon or boron is Y, Y/X is within the range of 1/10 to 1/10000. The present invention seeks to improve the Sb—Te base alloy sputtering target structure, inhibit the generation of cracks in the sintered target, and prevent the generation of arcing during the sputtering process.
