  • Fabrication of a multilayer conductive pattern on a dielectric substrate
    Patent number: 4774127
    Abstract: A pattern of conductive material is formed on a substrate of dielectric material. The substrate comprises a layer of flexible dielectric material having a layer of dimensionally-stable material adhered to one main face. The pattern is formed on the opposite main face of the layer of flexible dielectric material.
    Type: Grant
    Filed: June 15, 1987
    Date of Patent: September 27, 1988
    Assignee: Tektronix, Inc.
    Inventors: John J. Reagan, Peggy J. Parks, Nancy L. Miller, Robert L. Beckman
  • Polyimide embedded conductor process
    Patent number: 4650545
    Abstract: A polyimide embedded conductor process assures adherence of a metal conductor to a polyimide layer and allows closer spacing between conductors. The conductor is laid on a sacrificial substrate, and then the polyimide layer is laid over the conductor and substrate. The substrate is etched away to expose the conductor, and the polyimide layer may be etched away from the conductor to form attachment tabs.
    Type: Grant

    Date of Patent: March 17, 1987
    Assignee: Tektronix, Inc.
    Inventors: Carl W. Laakso, John J. Reagan, Robert L. Beckman
  • Coplanar microstrap waveguide interconnector and method of interconnection
    Patent number: 4600907
    Abstract: An electrical connection between two semiconductor devices employs a coplanar microstrap waveguide comprising a plurality of thin straps of conductive metal embedded in a polyimide substrate and dimensioned to exhibit the properties of a coplanar waveguide. The waveguide structure provides the proper impedance matching between the two devices and enables them to handle signals having frequencies in the gigahertz range.

  • Modified in situ retorting of oil shale
    Patent number: 4387768
    Abstract: Rubblized oil shale beds to be processed by the modified in situ retorting technique are U-shaped so that the inlet end and outlet end of the bed communicate with a common channel.
