Zusammenfassung:	A substrate support and method for fabricating the same are provided. In one embodiment of the invention, a substrate support includes an electrically conductive body having a substrate support surface that is covered by an electrically insulative coating. At least a portion of the coating centered on the substrate support surface has a surface finish of between about 80 to about 200 micro-inches. In another embodiment, a substrate support includes an anodized aluminum body having a surface finish on the portion of the body adapted to support a substrate thereon of between about 80 to about 200 micro-inches.
