Patent number: 8968537Abstract: Embodiments of the invention provide sputtering targets utilized in physical vapor deposition (PVD) and methods to form such sputtering targets. In one embodiment, a sputtering target contains a target layer disposed on a backing plate, and a protective coating layer—usually containing a nickel material—covering and protecting a region of the backing plate that would otherwise be exposed to plasma during the PVD processes. In many examples, the target layer contains a nickel-platinum alloy, the backing plate contains a copper alloy (e.g., copper-zinc), and the protective coating layer contains metallic nickel. The protective coating layer eliminates the formation of highly conductive, copper contaminants typically derived by plasma erosion of the copper alloy contained within the exposed surfaces of the backing plate. Therefore, the substrates and the interior surfaces of the PVD chamber remain free of such copper contaminants during the PVD processes.Type: GrantFiled: February 9, 2011Date of Patent: March 3, 2015Assignee: Applied Materials, Inc.Inventors: Muhammad M.
