Abrégé
(EN) Embodiments of the present disclosure generally relate to a substrate support having a two-part surface coating which reduces defect formation and back side metal contamination during substrate processing. A support body includes a body having an upper surface and a two-part coating disposed over the upper surface of the body. The two-part coating includes a first coating layer extending a first radial distance from a center of the body. The first coating layer includes at least one of a metal-containing material or alloy. The two-part coating includes a second coating layer disposed over the first coating layer. The second coating layer extends a second radial distance from the center of the body. The first radial distance is greater than the second radial distance. The second coating layer is non-metal.
(FR) Des modes de réalisation de la présente invention concernent généralement un support de substrat ayant un revêtement de surface en deux parties qui réduit la formation de défauts et la contamination de métal côté arrière pendant le traitement de substrat. Un corps de support comprend un corps ayant une surface supérieure et un revêtement en deux parties disposé sur la surface supérieure du corps. Le revêtement en deux parties comprend une première couche de revêtement s'étendant à une première distance radiale à partir d'un centre du corps. La première couche de revêtement comprend au moins l'un d'un matériau ou d'un alliage contenant du métal. Le revêtement en deux parties comprend une seconde couche de revêtement disposée sur la première couche de revêtement. La seconde couche de revêtement s'étend à une seconde distance radiale du centre du corps. La première distance radiale est plus grande que la seconde distance radiale. La seconde couche de revêtement est non métallique.
