Abstract: In various embodiments, used sputtering targets are refurbished at least in part by maintaining a large obliquity angle between the spray-deposition gun and the depressed surface contour of the target during spray deposition of the target material.

Abstract: A processing device includes a plurality of walls defining an interior space configured to be exposed to plasma and a surface coating on the interior surface of at least one of the plurality of walls. The surface coating includes pores forming interconnected porosity. The processing device further includes a sealant residing in at least a portion of the pores of the surface coating. In an embodiment, the sealant can be a thermally cured sealant having a cure temperature not greater than about 100° C. In another embodiment, the sealant can be an epoxy sealant having a viscosity of not greater than 500 cP in liquid precursor form. In yet another embodiment, the sealant can be a low shrinkage sealant characterized by a solidification shrinkage of not greater than 8%.

Abstract: An electrostatic chuck includes an insulating layer, a conductive layer overlying the insulating layer, a dielectric layer overlying the conductive layer, the dielectric layer having pores forming interconnected porosity, and a cured polymer infiltrant residing in the pores of the dielectric layer.
