Claim:
1. A support assembly for use in semiconductor processing comprising: an application substrate; a heater layer disposed directly onto the application substrate by a layered process selected from a group consisting of thick film, thin film, thermal spray and sol-gel processes such that the heater layer is in direct contact with the application substrate; an insulation layer disposed onto the heater layer; and a second substrate disposed onto the insulation layer, the second substrate including a base portion and a peripheral portion surrounding the base portion and extending vertically and upwardly from the base portion, wherein the application substrate defines a material having a relatively low coefficient of thermal expansion that is matched to a coefficient of thermal expansion of the heater layer, the application substrate functioning as an interface to be bonded to a heating substrate by a thermal process, and wherein a top surface of the peripheral portion of the second substrate is lower than a top surface of the application substrate and is exposed from the top surface of the application substrate such that a step is defined between the top surface of the application substrate and the top surface of the peripheral portion of the second substrate.
