Abstract: A method of improving the adhesion of processing materials on a ceramic component is described. The method includes the steps of forming a green ceramic component and texturing the surface of the green ceramic component. The as-textured component is then fired to harden the ceramic material. In an alternative embodiment of the method, a coating is applied to the surface of the as-fired ceramic component to provide a secondary adhesion layer. A ceramic component for use in an etching or deposition reactor chamber is also described. The ceramic component includes a substrate formed of a ceramic material and has a textured surface formed thereon such that the textured surface has a roughness of about 100 to 1000 ?in Ra.
