Field-enhanced sputtering targets are disclosed that include: a core material; and a surface material, wherein at least one of the core material or the surface material has a field strength design profile and wherein the sputtering target comprises a substantially uniform erosion profile. Target assembly systems are also disclosed that include a field-enhanced sputtering target; and an anodic shield. Additionally, methods of producing a substantially uniform erosion on a sputtering target are described that include: providing an anodic shield; providing a cathodic field-enhanced target; and initiating a plasma ignition arc, whereby the arc is located at the point of least resistance between the anodic shield and the cathodic field-enhanced target. |
