  • Method for fabricating integrated microelectronic assembly comprising photoconductor with oxide superconducting leads
    Patent number: 5304539
    Abstract: A beam (e.g. a focused laser beam) is utilized to irradiate the entire lateral width of a limited-extent portion of an elongated superconducting thin-film lead. The irradiated portion is converted to be non-superconducting and photoconductive. The converted portion constitutes a photodetector integrated with associated superconducting leads.
    Type: Grant
    Filed: May 12, 1992
    Date of Patent: April 19, 1994
    Assignee: Bell Communications Research, Inc.
    Inventors: Silas J. Allen, Robert R. Krchnavek
  • Method for the preparation of epitaxial ferromagnetic manganese aluminum magnetic memory element
    Patent number: 5169485
    Abstract: A non-volatile memory element based upon a thin epitaxial film of manganese aluminum upon a III-V semiconductor is described. The film is stable at elevated temperatures required for III-V semiconductor device processing, so permitting the monolithic integration of non-volatile memory elements with III-V semiconductor electronic and photonic devices.
