Abstract:
1. A bonded component assembly for use in a plasma processing apparatus for processing of semiconductor substrates, the component assembly comprising: a support member having at least one load bearing surface to support a component; the component supported on the at least one load bearing surface having at least one surface exposed to a plasma; and an elastomeric sheet adhesive joint between mating surfaces of the at least one load bearing surface and the component to allow movement in a lateral direction of the component relative to the support member during temperature cycling due to mismatch of thermal expansion of the support member and the component; wherein (a) the elastomeric sheet adhesive joint comprises an elastomeric sheet adhesive cast or rolled into a pre-form shape; (b) the elastomeric sheet adhesive joint comprises an elastomeric sheet adhesive of die cut pre-form shape; (c) the elastomeric sheet adhesive joint comprises an elastomeric sheet adhesive laser cut, plotter cut or water jet cut pre-form shape; or (d) one of the mating surfaces comprises a cavity.
