  • Circuit writing process
    Patent number: 4794087
    Abstract: Circuit writing on a substrate is achieved by selectively exposing to a laser portion of a very thin film of a medium comprising electrically isolated conducting clusters in a dielectric matrix material. The preferred materials are gold in highly crosslinked polytetrafluoroethylene.
    Type: Grant
    Filed: December 9, 1986
    Date of Patent: December 27, 1988
    Assignee: International Business Machines Corporation
    Inventors: Bernard Despax, Eric Kay
  • Etching process with vibrationally excited SF.sub.6
    Patent number: 4331504
    Abstract: A substrate which forms a volatile fluoride is etched and directionality is achieved using vibrationally excited SF.sub.6 which has been exposed to laser irradiation. The substrate is etched through a mask having openings smaller than the diffraction limit of the laser light.
    Type: Grant
    Filed: June 25, 1981
    Date of Patent: May 25, 1982
    Assignee: International Business Machines Corporation
    Inventors: Tung J. Chuang, John W. Coburn, Eric Kay
  • Plasma method for forming a metal containing polymer
    Patent number: 4226896
    Abstract: A plasma process for forming a polymer film containing metal therein includes the steps of providing an electrode of a metal that can be etched by a halogen, providing a substrate for the polymer film to be deposited thereon, and passing a halocarbon monomer through a plasma system so that the metal etched from the electrode forms a volatile halide and is incorporated in the polymer film that is deposited on the substrate.
