Abstract:
1. A method of joining an assembly for use in a plasma processing apparatus for processing a semiconductor substrate, comprising: applying a first surface of a sheet of uncured elastomeric adhesive in a predetermined pattern to at least one load bearing surface of a support member in a predetermined pattern of regions to be bonded which exclude regions to remain unbonded; applying at least one bonding surface of a component to a second surface of the sheet of uncured elastomeric adhesive in a predetermined pattern of regions to be bonded, the component having at least one other surface to be exposed to a plasma; and bonding the at least one bonding surface of the component to the at least one load bearing surface of the support member with the sheet of elastomeric adhesive therebetween to form the assembly; wherein the sheet of elastomeric adhesive is elastically deformable in the lateral direction to at least 500% shear strain by a shear stress of about 50 to 300 psi in a temperature range of room temperature to 300° C.
