Abstract:
A method of producing a sputtering target which comprises a target material comprising as constituent elements Ag, In, Te and Sb with the respective atomic percents (atom. %) of &agr;, &bgr;, &ggr; and &dgr; thereof being in the relationship of:0.5&lE;&agr;<8, 5&lE;&bgr;&lE;23, 17&lE;&ggr;&lE;38, 32&lE;&dgr;&lE;73, &agr;&lE;&bgr;, and &agr;+&bgr;+&ggr;+&dgr;=100, comprising the steps of: fusing a mixture of Ag, In and Te elements at a temperature in the range of 550Â° C. to 850Â° C. to prepare a fused mixture; rapidly cooling said fused mixture to prepare a solid lump; pulverizing said solid lump to prepare finely-divided particles; mixing said finely-divided particles with Sb; and sintering the mixture of said finely-divided particles and Sb.
