  • Semiconductor photodiode with integrated microporous filter
    Patent number: 6803581
    Abstract: A photodiode with integrated microporous filter formed on a semiconductor substrate is provided. The microporous filter will provide in excess of six orders of magnitude visible light reduction while transmitting a measurable amount of UV/EUV radiation. A process for manufacturing the photodiode with integrated microporous filter is also presented.
    Type: Grant
    Filed: July 30, 2002
    Date of Patent: October 12, 2004
    Assignee: International Radiation Detectors, Inc.
    Inventors: Chad J. Prince, Raj Korde
  • Semiconductor photodiode with back contacts
    Patent number: 6777729
    Abstract: A radiometric quality semiconductor photodiode with one electrical contact extending from a p-n junction at the photodiode surface to the back of the photodiode substrate and a second contact formed on the back of the semiconductor substrate is provided and a method for manufacturing is presented. The electrical contact channel extending from the p-n junction to the photodiode substrate will be formed by dry etching and will require a cross sectional area of only 0.125 mm×0.125 mm.
