Abstract: The present invention provides a method for producing nanometer-size spherical particles. The method includes a first step for producing intermediate spherical particles. The intermediate spherical particles include a polycrystalline or single-crystalline region, having a particle size of 1 to 300 μm. The method of the present invention further includes a second step for producing final spherical particles. The second step uses a swirling plasma gas flow having the central axis thereof, the central axis running through an area between an anode and a cathode of a plasma generator. The intermediate spherical particles are discharged along the axis to subject the intermediate spherical particles to a plasma atmosphere of the area to form the final spherical particles.

Abstract: Provided is an Sb—Te alloy sintered compact sputtering target having at least Sb or Te as its primary component, wherein surface roughness Ra is 0.4 μm or less, purity excluding gas components is 4N or more, content of gas components as impurities is 1500 ppm or less, and average crystal grain size is 50 μm or less. With this Sb—Te alloy sintered compact sputtering target, the density of defects having a maximum length of 10 μm or greater arising in a surface finish by machining is 80 or less in an 800 μm square. Thus, the Sb—Te alloy sputtering target structure can be uniformalized and refined, generation of cracks in the sintered target can be inhibited, and generation of arcing during sputtering can be inhibited. Further, surface ruggedness caused by sputter erosion can be reduced in order to obtain a high quality Sb—Te alloy sputtering target.
