ELECTROSTATIC CHUCK WITH MULTIPLE RADIO FREQUENCY MESHES TO CONTROL PLASMA UNIFORMITY

The present disclosure relates to a method and apparatus for controlling a plasma sheath near a substrate edge. Changing the voltage/current distribution across the inner electrode and the outer electrode with in the substrate assembly facilitates the spatial distribution of the plasma across the su...
