    摘要: A system and method of measuring a self bias DC voltage on a semiconductor wafer in a plasma chamber includes generating a plasma between a top electrode and a top surface of an electrostatic chuck in a plasma chamber including applying one or more RF signals to one or both of the top electrode and electrostatic chuck. The wafer is supported on the top surface of an electrostatic chuck. The self bias DC voltage is developed on the wafer. A vibrating electrode is oscillated to produce a variable capacitance, the vibrating electrode is located in the electrostatic chuck. An electrical current is developed in a sensor circuit. An output voltage is measured across a sampling resistor in the sensor circuit, a second DC potential is applied to the vibrating electrode to nullify the output voltage. The second DC potential is equal to the self bias DC voltage on the wafer.

    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.
