摘要： A method and apparatus for processing a substrate in a capacitively-coupled plasma processing system having a plasma processing chamber and at least an upper electrode and a lower electrode. The substrate is disposed on the lower electrode during plasma processing. The method includes providing at least a first RF signal, which has a first RF frequency, to the lower electrode. The first RF signal couples with a plasma in the plasma processing chamber, thereby inducing an induced RF signal on the upper electrode. The method also includes providing a second RF signal to the upper electrode. The second RF signal also has the first RF frequency. A phase of the second RF signal is offset from a phase of the first RF signal by a value that is less than 10%. The method further includes processing the substrate while the second RF signal is provided to the upper electrode.

摘要： Methods and apparatus for operating the plasma processing chamber of a plasma processing tool in at least two modes are disclosed. In the first mode, the substrate-bearing assembly is movable within a gap-adjustable range to adjust the gap between the electrodes to accommodate different processing requirements. In this first mode, RF ground return path continuity is maintained irrespective of the gap distance as long as the gap distance is within the gap-adjustable range. In the second mode, the substrate bearing assembly is capable of moving to further open the gap to accommodate unimpeded substrate loading/unloading.

摘要： A plasma processing system having a plasma processing chamber configured for processing a substrate is provided. The substrate is disposed above a chuck and surrounded by an edge ring, which is electrically isolated from the chuck. The system includes a RF power, which provides power to the chuck. The system also includes a tunable capacitance arrangement, which is coupled to the edge ring to provide RF coupling to the edge ring, resulting in the edge ring having an edge ring potential. The system further includes the plasma processing chamber configured to strike plasma to process the substrate, which is processed while the tunable capacitance arrangement is configured to cause the edge ring potential to be dynamically tunable to a DC potential of the substrate while processing the substrate.
