Patent number: 8581254Abstract: The present approach involves a radiation detector module with increased quantum efficiency and methods of fabricating the radiation detector module. The module includes a scintillator substrate and a photodetector fabricated on the scintillator substrate. The photodetector includes an anode, active organic elements, and a cathode. The module also includes a pixel element array disposed over the photodetector. During imaging, radiation attenuated by an object to be imaged may propagate through the pixel element array and through the layers of the photodetector to be absorbed by the scintillator which in response emits optical photons. The photodetector may absorb the photons and generate charge with improved quantum efficiency, as the photons may not be obscured by the cathode or other layers of the module. Further, the module may include reflective materials in the cathode and at the pixel element array to direct optical photons towards the active organic elements.Type: GrantFiled: September 30, 2011Date of Patent: November 12, 2013Assignee: General Electric CompanyInventors: Aaron Judy Couture, Steven Jude Duclos, Joseph John Shiang, Gautam Parthasarathy

Patent number: 8569814Abstract: The energy distribution in the short-side direction of a rectangular laser beam applied to an amorphous semiconductor film (amorphous silicon film) is uniformized. It is possible to the energy distribution in the short-side direction of the rectangular laser beam by the use of a cylindrical lens array or a light guide and concentrating optical systems or by the use of an optical system including a diffracting optical element. Accordingly, since the effective energy range of a laser beam applied to the amorphous semiconductor film is widened and the transport speed of a substrate can be enhanced as much, it is possible to improve the processing ability of the laser annealing.Type: GrantFiled: August 31, 2011Date of Patent: October 29, 2013Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Kenichiro Nishida, Ryusuke Kawakami, Norihito Kawaguchi, Miyuki Masaki

Patent number: 8558292Abstract: A vertically-integrated active pixel sensor includes a sensor wafer connected to a support circuit wafer. Inter-wafer connectors or connector wires transfer signals between the sensor wafer and the support circuit wafer. The active pixel sensor can be fabricated by attaching the sensor wafer to a handle wafer using a removable interface layer. Once the sensor wafer is attached to the handle wafer, the sensor wafer is backside thinned to a given thickness. The support circuit wafer is then attached to the sensor wafer and the handle wafer separated from the sensor wafer.Type: GrantFiled: June 11, 2010Date of Patent: October 15, 2013Assignee: OmniVision Technologies, Inc.Inventor: Robert M.
