摘要： A plasma processing system for use with a gas. The plasma processing system comprises a first electrode, a second electrode, a gas input port, a power source and a passive circuit. The gas input port is operable to provide the gas between the first electrode and the second electrode. The power source is operable to ignite plasma from the gas between the first electrode and the second electrode. The passive circuit is coupled to the second electrode and is configured to adjust one or more of an impedance, a voltage potential, and a DC bias potential of the second electrode. The passive radio frequency circuit comprises a capacitor arranged in parallel with an inductor.

摘要： A combined pressure control/plasma confinement assembly configured for confining a plasma and for at least partially regulating pressure in a plasma processing chamber during plasma processing of a substrate is provided. The assembly includes a movable plasma confinement structure having therein a plurality of perforations and configured to surround the plasma when deployed. The assembly also includes a movable pressure control structure disposed outside of the movable plasma confinement structure such that the movable plasma confinement structure is disposed between the plasma and the movable pressure control structure during the plasma processing, the movable pressure control structure being deployable and retractable along with the movable plasma confinement structure to facilitate handling of the substrate, the movable pressure control structure being independently movable relative to the movable plasma confinement structure to regulate the pressure by blocking at least a portion of the plurality of perforations.
