Claim 11:
12. A method of processing a plurality of substrates, the method comprising: powering an RF source connected to a first electrode in a first plasma processing station and a second electrode in a second plasma processing station to form a top RF path, the first plasma processing station and second plasma processing station arranged around an interior of a processing chamber comprising a plurality of processing stations, a wafer pedestal having a plurality of heaters to support individual wafers for processing, the number of heaters equal to the number of processing stations, the plurality of heaters comprising a first heater and a second heater, the first heater adjacent to and spaced from the first electrode and the second heater adjacent to and spaced from the second electrode, a connection is between the first heater and the second heater of the wafer pedestal to form a bottom RF path, wherein current flows in one direction from the RF source to the first electrode, to the first heater, through the connection between the first heater and the second heater to the second heater and then back to the RF source.
