Abstract

A substrate processing system includes a processing chamber including a dielectric window and a substrate support arranged therein to support a substrate. A coil is arranged outside of the processing chamber adjacent to the dielectric window. A Faraday shield is arranged between the coil and the dielectric window. An RF generator is configured to supply RF power to the coil. The coil is coupled by stray capacitance and/or directly coupled to the Faraday shield. A capacitor is connected to one of the coil and the Faraday shield to adjust a position of a voltage standing wave along the coil.
