Abstract:
A heating plate for use in a substrate support is configured to provide temperature profile control of a substrate supported on the substrate support in a vacuum chamber of a substrate processing apparatus. The heating plate includes an independently controllable heater zones operable to tune a temperature profile on an upper surface of the heating plate. The heater zones are each powered by two or more power lines wherein each power line is electrically connected to a different group of the heater zones and each respective heater zone is electrically connected to a different pair of power lines.
