Patents by Inventor John F. Eger

John F. Eger 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: 9318627
    Abstract: A semiconductor radiation detector having a semiconductor substrate and first and second metal layers. The semiconductor substrate has substantially planar upper and lower opposing surfaces which have respective first and second surface areas. The first and second surface areas are defined by prospective dice lines. The first metal layer is on the substantially planar upper surface such that the first metal layer will have a surface area less than the first surface area of the substantially planar upper surface as defined by spaces on the substantially planar upper surface between the first metal layer and the prospective dice lines which define the first surface area. The second metal layer is on the substantially planar lower opposing surface.
    Type: Grant

  • Patent number: 8742522
    Abstract: A method of making a semiconductor radiation detector wherein the metal layers which serve as the cathode and anode electrodes are recessed from the designated prospective dice lines which define the total upper and lower surface areas for each detector such that the dicing blade will not directly engage the metal during dicing and therefore prevent metal from intruding upon (smearing) the vertical side walls of the detector substrate.
