Patents by Inventor Gottfried H. Dohler

Gottfried H. Dohler 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).

  • Selective NIPI doping super lattice contacts and other semiconductor device structures formed by shadow masking fabrication
    Patent number: 4883770
    Abstract: A molecular beam epitaxy (MBE) process in which some portions of the substrate are shadowed by a shadow mask from receiving at least one of the molecular beams used in the MBE process. This process is capable of producing NIPI superlattices that have selective contacts that are far superior to those which can be produced at present. This technique can also produce a wide variety of NIPI devices as well as other types of IC structures.
