  • Publication number: 20130334170
    Abstract: Techniques for fabricating thin single crystal diamond films from a diamond structure having a top surface including implanting a dose of ions at a predetermined depth below the top surface to form a damage layer, selectively masking the top surface to expose one or more portions of the diamond structure, vertically etching one or more of the exposed portions to the predetermined depth, and exfoliating the unexposed portion to form at least one thin single crystal diamond film.

  • Patent number: 7501634
    Abstract: A large format imager includes an array of pixels for converting electromagnetic radiation into electrical signals and a trigger to from an optical pulse so as to trigger the pixels to generate an integration period. Each pixel includes a photodiode to convert light intensity of high-frequency radiation into an electrical charge, a reset switch to reset the photodiode, circuitry to enable sampling of the electrical charge produced by the photodiode, a photoswitch to convert an optical trigger pulse, received from the trigger, into an electrical signal, an inverter to produce a control signal corresponding to the electrical signal produced by the photoswitch, and control circuitry to locally generate integration control signals. The integration control signals control a start of an integration period for the photodiode, duration of the integration period for the photodiode, and the sampling of the electrical charge produced by the photodiode.

  • Publication number: 20070042516
    Abstract: A method is provided for fabricating thin membrane structures in localized surface regions of a single crystal substrate. In the method, ion implantation masks are patterned on the surface of the single crystal substrate with openings that define the localized surface regions. Foreign ions are implanted through the openings into the single crystal substrate to modify the chemical and/or structural properties of subsurface layers at predetermined depths underneath super layers of material. These subsurface layers are removed by selective etching. The removal of the subsurface layers leaves the super layers of material intact as membrane structures on top of openings or channels corresponding to the space of the removed subsurface layers. At least one portion or end of a membrane structure remains attached to the single crystal substrate.
