  • Patent number: 5466991
    Abstract: The present invention describes a technique to control the radial profile of microwave power in an ECR plasma discharge. In order to provide for a uniform plasma density to a specimen, uniform energy absorption by the plasma is desired. By controlling the radial profile of the microwave power transmitted through the microwave window of a reactor, the profile of the transmitted energy to the plasma can be controlled in order to have uniform energy absorption by the plasma. An advantage of controlling the profile using the window transmission characteristics is that variations to the radial profile of microwave power can be made without changing the microwave coupler or reactor design.

  • Patent number: 5306300
    Abstract: A tubular digestive screen for use in controlling the caloric intake of persons having morbid obesity is disclosed. The screen is made up of a thin-walled membrane-like tube, which has a firm ring at the top of the tube, a funnel-shaped portion below the firm ring, a tubular portion of constant diameter beginning below the funnel-shaped portion, and a distal end of the tube having a brush. The screen can be inserted and maintained in the digestive system of a patient without the need for an anchoring chain within the tube.

  • Patent number: 5032202
    Abstract: A plasma generating apparatus for plasma processing applications is based on a permanent magnet line-cusp plasma confinement chamber coupled to a compact single-coil microwave waveguide launcher. The device creates an electron cyclotron resonance (ECR) plasma in the launcher and a second ECR plasma is created in the line cusps due to a 0.0875 tesla magnetic field in that region. Additional special magnetic field configuring reduces the magnetic field at the substrate to below 0.001 tesla. The resulting plasma source is capable of producing large-area (20-cm diam), highly uniform (.+-.5%) ion beams with current densities above 5 mA/cm.sup.2. The source has been used to etch photoresist on 5-inch diam silicon wafers with good uniformity.
