  • Patent number: 10685810
    Abstract: An apparatus for generating plasma, including a quadrupole antenna having a center region and an outer region and configured to be disposed over a dielectric window of a plasma chamber. The quadrupole antenna including a first coil defining a first SDA and a second coil defining a second SDA, the first coil being in a nested arrangement within the second coil. The nested arrangement places a turn of the first coil to be adjacent to a corresponding turn of the second coil as the first and second coils spiral from the center region to the outer region of the quadrupole antenna. Adjacent turns of each of the first and second coils are horizontally separated from one another by a distance when disposed over the dielectric window.

  • Patent number: 10447775
    Abstract: Provided are methods and systems for balancing servers based on a server load status. A method for balancing servers based on a server load status may commence with receiving, from a server of a plurality of servers, a service response to a service request. The service response may include a computing load of the server. The method may continue with receiving a next service request from a host. The method may further include determining, based on the computing load of the server, whether the server is available to process the next service request. The method may include selectively sending the next service request to the server based on the determination that the server is available to process the next service request.

  • Patent number: 10395903
    Abstract: 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.

  • Patent number: 10388528
    Abstract: This disclosure relates to a plasma processing system for controlling plasma density near the edge or perimeter of a substrate that is being processed. The plasma processing system may include a plasma chamber that can receive and process the substrate using plasma for etching the substrate, doping the substrate, or depositing a film on the substrate. This disclosure relates to a plasma processing system that may be configured to enable non-ambipolar diffusion to counter ion loss to the chamber wall. The plasma processing system may include a ring cavity coupled to the plasma processing system that is in fluid communication with plasma generated in the plasma processing system. The ring cavity may be coupled to a power source to form plasma that may diffuse ions into the plasma processing system to minimize the impact of ion loss to the chamber wall.

  • Patent number: 10375812
    Abstract: A surface wave plasma (SWP) source couples microwave (MW) energy into a processing chamber through, for example, a radial line slot antenna, to result in a low mean electron energy (Te). An ICP source, is provided between the SWP source and the substrate and is energized at a low power, less than 100 watts for 300 mm wafers, for example, at about 25 watts. The ICP source couples energy through a peripheral electric dipole coil to reduce capacitive coupling.
