  • Focal plane photo-detector mosaic array apparatus
    Patent number: 4449044
    Abstract: A focal plane detector mosaic array is formed by securing wafers of the detector material to a focal plane having individual conductor leads embedded therein, ion milling to delineate separate detector islands in individual electrical contact with the conductor leads, and using ion implantation to form p-n junctions in the detector islands.
    Type: Grant
    Filed: May 11, 1981
    Date of Patent: May 15, 1984
    Assignee: Carson Alexion Corporation
    Inventors: Ralph A. Rotolante, Toivo Koehler

  • Method of forming a mercury cadmium telluride photodiode
    Patent number: 4206003
    Abstract: A mercury cadmium telluride photodiode includes an n-type mercury cadmium telluride body with an accumulation layer proximate a first surface of the body. A p-type region is formed in the body at the first surface so that the n-type accumulation layer surrounds the p-type region at the first surface.
