Abstract:
1. A method of powering an electrode system driving a plasma chamber, the method comprising: coupling M power generators to N feed points on an electrode system, absorbing power at K of the N feed points, where 0<K<N, and delivering power at the other N−K feed points; controlling an impedance presented to the K feed points and controlling the phase and amplitude of delivered power at the other N−K feed points; and converting the power absorbed at one of the K feed points into power useable by one of the N−K feed points; wherein the M power generators are coupled to the N feed points on an electrode system via a M+N port network such that the total power delivered to the N feed points is equal to the total power taken from the M generators except for losses in the M+N port network; wherein the power delivered by each of the M generators are equal.
