摘要： 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.

摘要： A plasma in a vacuum chamber where a workpiece is processed is bounded by a plasma confinement volume including a region between a first electrode simultaneously responsive to power at first and second RF frequencies and a DC grounded second electrode. A DC grounded extension is substantially aligned with the first electrode. A substantial percentage of power at the first frequency is coupled to a path including the first and second electrodes but not the extension while a substantial percentage of power at the second frequency is coupled to a path including the first electrodes and extension, but not the second electrode. Changing the relative powers at the first and second frequencies, as applied to the first electrode, controls DC bias voltage of the first electrode.
