Patents by Inventor Edwin Pease

Edwin Pease has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Metamorphic buffer on small lattice constant substrates
    Patent number: 7633083
    Abstract: A semiconductor device is supported by a substrate with a smaller lattice constant. A metamorphic buffer provides a transition from the smaller lattice constant of the substrate to the larger lattice constant of the semiconductor device. In one application, the semiconductor device has a lattice constant of between approximately 6.1 and 6.35 angstroms, metamorphic buffer layers include Sb (e.g., AlInSb buffer layers), and the substrate has a smaller lattice constant (e.g., Si, InP or GaAs substrates).
    Type: Grant
    Filed: March 10, 2005
    Date of Patent: December 15, 2009
    Assignee: STC.UNM
    Inventors: Luke F. Lester, Larry R. Dawson, Edwin A. Pease
