    摘要: A Ge—Cr alloy sputtering target containing 5 to 50 at % of Cr and having a relative density of 95% or more, and a manufacturing method of such a Ge—Cr alloy sputtering target wherein Cr powder having a minus sieve of 75 μm or less, and Ge powder having a minus sieve of 250 μm or less and having a BET specific surface area of 0.4 m2/g or less are dispersively mixed in an even manner, and sintered thereafter. Thereby provided is a Ge—Cr alloy sputtering target capable of suppressing variation of the deposition speed and film composition, as well as improving the production yield, of the GeCrN layer deposited with reactive sputtering as the intermediate layer between the recording layer and protective layer of a phase change optical disk, and the manufacturing method of such a target.

    摘要: The present invention provides a sputtering target for a phase change memory and a phase change memory film formed with such a target, and the manufacturing method thereof, characterized in that the sputtering target is composed from elements of not less than a three component system and has as its principal component one or more components selected from stibium, tellurium and selenium, and the compositional deviation in relation to the intended composition is ±1.0 at % or less. This sputtering target for a phase change memory is capable of reducing, as much as possible, impurities that cause the reduction in the number of times rewriting can be conducted as a result of such impurities segregating and condensing in the vicinity of the boundary face of the memory point and non-memory point; in particular, impurity elements that affect the crystallization speed, reducing the compositional deviation of the target in relation to the intended composition, and improving the rewriting properties and crystallization speed of a phase change memory by suppressing the compositional segregation of the target.

    摘要: Provided is a ferromagnetic sputtering target having a composition containing 20 mol % or less of Cr, 5 to 30 mol % of Pt, 5 to 15 mol % of SiO2, 0.05 to 0.60 mol % of Sn, with Co as a remainder thereof, wherein the Sn is contained in SiO2 particles (B) dispersed in a metal substrate (A). The method yields a ferromagnetic sputtering target containing dispersed nonmagnetic particles. The target can prevent the abnormal electrical discharge of oxides which causes the generation of particles during sputtering.
