发明名称 PRE-CONDITIONING A SPUTTERING TARGET PRIOR TO SPUTTERING
摘要 A sputtering target is pre-conditioned prior to use of the target in a sputtering process by removing a damaged surface layer of a sputtering surface of the target. In one version, the sputtering surface of the sputtering target is lapped to remove a thickness of at least about 25 microns to obtain a sputtering surface having a surface roughness average of from about 4 to about 32 microinches. In another version, an acidic etchant is used to remove the layer. In yet another version, the damaged surface layer is annealed by heating the surface.
