James A. Real 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).

  • Apparatus and method for accurate measurement and mapping of forward and reverse-bias current-voltage characteristics of large area lateral p-n junctions
    Patent number: 9746514
    Abstract: Methods and apparatus for providing measurements in p-n junctions and taking into account the lateral current for improved accuracy are disclosed. The lateral current may be controlled, allowing the spreading of the current to be reduced or substantially eliminated. Alternatively or additionally, the lateral current may be measured, allowing a more accurate normal current to be calculated by compensating for the measured spreading. In addition, the techniques utilized for controlling the lateral current and the techniques utilized for measuring the lateral current may also be implemented jointly.
