  • Silicon carbide schottky diode
    Publication number: 20070090481
    Abstract: A SiC Schottky diode which includes a Schottky barrier formed on a silicon face 4H—SiC body.
    Type: Application
    Filed: October 16, 2006
    Publication date: April 26, 2007
    Inventor: Giovanni Richieri
  • Trench schottky device with single barrier
    Publication number: 20070087493
    Abstract: A process for forming a trench Schottky barrier device includes the forming of an oxide layer within the trenches in the surface of a silicon wafer, and then depositing a full continuous metal barrier layer over the full upper surface of the wafer including the trench interiors and the mesas between trenches with a barrier contact made to the mesas only. Palladium, titanium or any conventional barrier metal can be used.
    Type: Application

  • Method of forming ohmic contact to a semiconductor body
    Publication number: 20060003514
    Abstract: A process for forming an ohmic contact on the back surface of a semiconductor body includes depositing a donor layer on the back surface of the semiconductor body followed by a sintering step to form a shallow intermetallic region capable of forming a low resistance contact with a contact metal.
