Claim 0:
1. A substrate support assembly comprising:
an electrostatic chuck body defining a substrate support surface;
a first bipolar electrode embedded within the electrostatic chuck body beneath the substrate support surface;
a second bipolar electrode embedded within the electrostatic chuck beneath the substrate support surface, wherein the first bipolar electrode and the second bipolar electrode are separated by a gap;
a third electrode positioned radially outward from and extending about the first bipolar electrode and the second bipolar electrode
a connection for a first radio frequency (RF) power supply or variable capacitor coupled with the first bipolar electrode and/or the second bipolar electrode; and
a connection for a second RF power supply or variable capacitor coupled with the third bipolar electrode.
