Abstract:
A plasma processing chamber and methods for operating the chamber are provided. An exemplary chamber includes an electrostatic chuck for receiving a substrate and a dielectric window connected to a top portion of the chamber. An inner side of dielectric window faces a plasma processing region that is above the electrostatic chuck and an outer side of the dielectric window is exterior to the plasma processing region. Inner and outer coils are disposed above the outer side of the dielectric window, and the inner and outer coils are connected to a first RF power source. A powered grid is disposed between the outer side of dielectric window and the inner and outer coils. The powered grid is connected to a second RF power source that is independent from the first RF power source.

Claim (Index 14):
The power grid of  claim 10 , wherein the metal layer is configured to be coupled to a first radio frequency (RF) generator to receive an RF signal having a frequency of about 2 megahertz (MHz), wherein upon reception of the RF signal, the metal layer is configured to facilitate generation of ion energies within a plasma sheath to further control direct current (DC) bias of plasma near the dielectric window, wherein the DC bias is controlled to decrease adhesion of byproducts of a plasma process to a surface of the dielectric window, wherein the inductive coil is configured to be coupled to a second RF generator to receive an RF signal from the second RF generator.
