Abstract:
Systems and methods for controlling directionality of ion flux at an edge region within a plasma chamber are described. One of the systems includes a radio frequency (RF) generator that is configured to generate an RF signal, an impedance matching circuit coupled to the RF generator for receiving the RF signal to generate a modified RF signal, and a plasma chamber. The plasma chamber includes an edge ring and a coupling ring located below the edge ring and coupled to the first impedance matching circuit to receive the modified RF signal. The coupling ring includes an electrode that generates a capacitance between the electrode and the edge ring to control the directionality of the ion flux upon receiving the modified RF signal.

Claim (Index 7):
The coupling ring of  claim 1 , wherein the top surface of the insulator ring is located adjacent to an edge ring of the plasma chamber, and the bottom surface of the coupling ring is located adjacent to an insulator ring of the plasma chamber.
