Abstract: Spatial distribution of RF power delivered to plasma in a processing chamber is controlled using an arrangement of primary and secondary inductors, wherein the current through the secondary inductors affects the spatial distribution of the plasma. The secondary inductors are configured to resonate at respectively different frequencies. A first secondary inductor is selectively excited to resonance, during a first time period within a duty cycle, by delivering power to a primary inductor at the resonant frequency of the first secondary inductor.

The secondary inductors are isolated from one another and terminated such that substantially all current that passes through them and into the plasma results from mutual inductance with a primary inductor.
