TARGET DESIGNS AND RELATED METHODS FOR REDUCED EDDY CURRENTS, INCREASED RESISTANCE AND RESISTIVITY, AND ENHANCED COOLING

摘要

A sputtering target is described herein that comprises: a) a target surface component comprising a target material; b) a core backing component having a coupling surface and a back surface, wherein the coupling surface is coupled to the target surface component; and c) at least one surface area feature coupled to or located in the back surface of the core backing component, wherein the surface area feature increases the resistance, resistivity or a combination thereof of the core backing component. Methods of forming a sputtering target are also described that comprises: a) providing a target surface component comprising a surface material; b) providing a core backing component comprising a backing material and having a coupling surface and a back surface; c) providing at least one surface area feature coupled to or located in the back surface of the core backing component, wherein the surface area feature increases the resistance, resistivity or a combination thereof of the core backing component; and d) coupling the surface target material to the coupling surface of the core backing material.
