    Abstract: A method for processing a plurality of substrates in a plasma processing chamber of a plasma processing system, each of the substrate being disposed on a chuck and surrounded by an edge ring during the processing. The method includes processing a first substrate of the plurality of substrates in accordance to a given process recipe in the plasma processing chamber. The method further includes adjusting, thereafter, a capacitance value of a capacitance along a capacitive path between a plasma sheath in the plasma processing chamber and the chuck through the edge ring by a given value. The method additionally includes processing a second substrate of the plurality of substrates in accordance to the given process recipe in the plasma processing chamber after the adjusting, wherein the adjusting is performed without requiring a change in the edge ring.
