ARRAYS OF INDUCTIVE ELEMENTS FOR MINIMIZING RADIAL NON-UNIFORMITY IN PLASMA
Abstract:
An arrangement for enabling local control of power delivery within a plasma processing system having a plasma processing chamber during processing of a substrate is provided. The arrangement includes a dielectric window and an inductive arrangement. The inductive arrangement is disposed above the dielectric window to enable power to couple with a plasma in the plasma processing system. The inductive arrangement includes a set of inductive elements, which provides the local control of power delivery to create a substantially uniform plasma in the plasma processing chamber.
