    摘要: A sputtering target is described herein, which includes: a) a surface material, and b) a core material coupled to the surface material, wherein at least one of the surface material or the core material has less than 100 ppm defect volume. Methods for producing sputtering targets are described that include: a) providing at least one sputtering target material, b) melting the at least one sputtering target material to provide a molten material, c) degassing the molten material, d) pouring the molten material into a target mold. In some embodiments, pouring the molten material into a target mold comprises under-pouring or under-skimming the molten material from the crucible into the target mold. Sputtering targets and related apparatus formed by and utilizing these methods are also described herein. In addition, uses of these sputtering targets are described herein.
