Patent ID: 8147909

Claim:
A method for processing a wafer, comprising: providing an alloy susceptor comprising an exterior surface and a wafer contact surface; treating the exterior surface to produce a roughness of the exterior surface, wherein the wafer contact surface is not treated; coating the roughened exterior surface with a ceramic material, wherein the wafer contact surface is not coated; positioning the alloy susceptor comprising the ceramic-coated roughened exterior surface in a wafer process chamber; and depositing a plurality of layers of film, each of the plurality of layers of film being of a different material than the ceramic material, on the ceramic-coated roughened exterior surface of the alloy susceptor, wherein a first adhesion exists between the plurality of layers of film and the ceramic material coated on the roughened exterior surface of the alloy susceptor that is greater than a second adhesion that would exist between the plurality of layers of film and a non-roughened exterior surface of the alloy susceptor without the ceramic material.
