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.

Method of forming a composite substrate for layered heaters

A heater assembly for use in semiconductor processing that includes an application substrate; a heater substrate secured to the application substrate by a thermal bonding process; and a functional layer disposed onto the heater substrate by a layered process. In this heater assembly, 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.

Composite substrate for layered heaters

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 to the heater substrate after the heater substrate is secured to the application substrate. The application of the layered heater includes applying a first dielectric layer onto the heater substrate, applying a resistive heating layer onto the first dielectric layer, and applying a second dielectric layer onto the resistive heating layer. The heater substrate defines a material having a coefficient of thermal expansion that is matched to a coefficient of thermal expansion of at least one of the first dielectric layer and a coefficient of thermal expansion of the resistive heating layer.
