Abstract
A method of forming a heater assembly for use in semiconductor processing includes thermally securing a heater substrate to an application substrate; and applying a layered heater having at least one functional layer to the heater substrate after the heater substrate is secured to the application substrate. The heater substrate defines a material having a coefficient of thermal expansion that is matched to a coefficient of thermal expansion of the functional layer. The material of the functional layer is not capable of withstanding the elevated temperature of the thermal securing step.
