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 20):
The coupling ring of  claim 12 , wherein the electrode is a ring-shaped electrode and is flat.
