    Abstract: system and method of cleaning a substrate (202) includes a megasonic chamber (206) that includes a transducer (210) and a substrate (202). The transducer (210) is being oriented toward the substrate (202). A variable distance d separates the transducer (210) and the substrate (202). The system (200) also includes a dynamically adjustable RF generator (212) that has an output coupled to the transducer. The dynamically adjustable RF generator (212) can be controlled by a phase comparison of an oscillator output (306) voltage and a phase of an RF generator output voltage. The dynamically adjustable RF generator (212) can also be controlled by monitoring a peak voltage of an output signal and controlling the RF generator to maintain the peak voltage within a predetermined voltage range. The dynamically adjustable RF generator (212) can also be controlled by dynamically controlling a variable DC power supply voltage.

    Abstract: A method in a plasma processing system for processing a semiconductor substrate is disclosed. The plasma processing system includes a plasma processing chamber and an electrostatic chuck coupled to a bias compensation circuit. The method includes igniting a plasma in a plasma ignition step. Plasma ignition step is performed while a first bias compensation voltage provided by the bias compensation circuit to the chuck is substantially zero and while a first chamber pressure within the plasma processing chamber is below about 90 mTorr. The method further includes processing the substrate in a substrate-processing step after the plasma is ignited. The substrate-processing step employs a second bias compensation voltage provided by the bias compensation circuit that is higher than the first bias compensation voltage and a second chamber pressure substantially equal to the first chamber pressure.
