摘要： A processing system is disclosed, having an electron beam source chamber that excites plasma to generate an electron beam, and an ion beam source chamber that houses a substrate and also excites plasma to generate an ion beam. The processing system also includes a dielectric injector coupling the electron beam source chamber to the ion beam source chamber that simultaneously injects the electron beam and the ion beam and propels the electron beam and the ion beam in opposite directions. The voltage potential gradient between the electron beam source chamber and the ion beam source chamber generates an energy field that is sufficient to maintain the electron beam and ion beam as a plasma treats the substrate so that radio frequency (RF) power initially applied to the processing system to generate the electron beam can be terminated thus improving the power efficiency of the processing system.

摘要： A method of generating a signal representing with an ion energy analyzer for use in determining an ion energy distribution of a plasma. The ion energy analyzer, used for determining an ion energy distribution of a plasma, includes a first grid and a second grid that is spaced away from and electrically isolated from the first grid. The first grid forms a first surface of the ion energy analyzer and is positioned to be exposed to the plasma. The first grid includes a first plurality of openings, which are dimensioned to be less than a Debye length for the plasma. A voltage source and an ion current meter are operably coupled to the second grid, the latter of which is configured to measure an ion flux onto the ion collector and to transmit a signal that represents the measured ion flux. The method includes selectively and variably biasing the second grid relative to the first grid.

摘要： A routing system utilizes a layer 2 switch interconnecting several routers to intelligently forward multicast packets throughout an internet exchange carrying multicast content. The layer 2 switch performs protocol snooping to extract a lookup key that is based on network layer protocol information. The lookup key is uniquely formulated to support either shared or explicit source distribution trees. The lookup key is used to query a forwarding memory that returns an outgoing port index. The outgoing port index points to one or more outgoing ports that are eligible to receive the multicast packet. The outgoing ports are also connected to the neighboring device(s) that are designated to receive the multicast packet. The routing system also supports real time maintenance and updating of the forwarding memory based on the periodic exchange of control messages. The routing system is configured to support PIM routers operating in PIM SM or PIM SSM modes. However, the routing system can also support other multicast protocols and/or standards.
