Abstract:
1. A sputtering target, comprising: a front target surface; a back target surface opposite the front target surface; a target surface component comprising a target material; and a core backing component having a coupling surface, a back surface, a thickness and at least one opening or open area through the thickness of the core backing component, wherein at least a portion of the target surface component is disposed within the at least one opening or open area of the core backing component such that the back surface of the core backing component and a portion of the target surface component form the back target surface of the sputtering target, and wherein the coupling surface of the core backing component is coupled to the target surface component at a plurality of localized, discrete welds, and wherein at least a portion of the target surface component is coplanar with the back surface of the core backing component, and wherein the target surface component is continuous at the front target surface in a direction transverse to a longitudinal axis extending through the front target surface and the back target surface.
