Patents by Inventor Hartmut F.W. Sadrozinski

Hartmut F.W. Sadrozinski 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).

  • Patent number: 9613993
    Abstract: Position sensitive radiation detection is provided using a continuous electrode in a semiconductor radiation detector, as opposed to the conventional use of a segmented electrode. Time constants relating to AC coupling between the continuous electrode and segmented contacts to the electrode are selected to provide position resolution from the resulting configurations. The resulting detectors advantageously have a more uniform electric field than conventional detectors having segmented electrodes, and are expected to have much lower cost of production and of integration with readout electronics.
    Type: Grant
    Filed: June 30, 2016
    Date of Patent: April 4, 2017
    Assignee: The Regents of the University of California
    Inventors: Hartmut F. W. Sadrozinski, Abraham Seiden, Nicolo Cartiglia

  • Patent number: 8841170
    Abstract: A method of singulating semiconductor devices in the close proximity to active structures by controlling interface charge of semiconductor device sidewalls is provided that includes forming a scribe on a surface of a semiconductor devices, where the scribe is within 5 degrees of a crystal lattice direction of the semiconductor device, cleaving the semiconductor device along the scribe, where the devices are separated, using a coating process to coat the sidewalls of the cleaved semiconductor device with a passivation material, where the passivation material is disposed to provide a fixed charge density at a semiconductor interface of the sidewalls, and where the fixed charge density interacts with charge carriers in the bulk of the material.
