Abstract:
A substrate support is provided, is configured to support a substrate in a plasma processing chamber, and includes first, second and third insulative layers, conduits and leads. The first insulative layer includes heater zones arranged in rows and columns. The second insulative layer includes conductive vias. First ends of the conductive vias are connected respectively to the heater zones. Second ends of the conductive vias are connected respectively to power supply lines. The third insulative layer includes power return lines. The conduits extend through the second insulative layer and into the third insulative layer. The leads extend through the conduits and connect to the heater zones. The heater zones are connected to the power return lines by the leads and are configured to heat corresponding portions of the substrate to provide a predetermined temperature profile across the substrate during processing of the substrate in the plasma processing chamber.
