  • Patent number: 9395453
    Abstract: A radiation sensor includes a scintillation layer configured to emit photons upon interaction with ionizing radiation and a photodetector including in order a first electrode, a photosensitive layer, and a photon-transmissive second electrode disposed in proximity to the scintillation layer. The photosensitive layer is configured to generate electron-hole pairs upon interaction with a part of the photons. The radiation sensor includes pixel circuitry electrically connected to the first electrode and configured to measure an imaging signal indicative of the electron-hole pairs generated in the photosensitive layer and a planarization layer disposed on the pixel circuitry between the first electrode and the pixel circuitry such that the first electrode is above a plane including the pixel circuitry. A surface of at least one of the first electrode and the second electrode at least partially overlaps the pixel circuitry and has a surface inflection above features of the pixel circuitry.

  • Patent number: 9065010
    Abstract: A method of fabricating an optoelectronic device includes creating an optoelectronic structure on a first substrate. The optoelectronic structure includes a release layer and a plurality of inorganic semiconductor layers supported by the release layer. The plurality of inorganic semiconductor layers is configured to be active in operation of the optoelectronic device. The plurality of inorganic semiconductor layers are permanently attached to a second substrate, which is flexible. The plurality of inorganic semiconductor layers are released from the first substrate after the attaching step, and the second substrate is deformed to a non-planar configuration.

  • Patent number: 8745853
    Abstract: Disclosed herein is a method of fabricating an antenna in which a flexible stamp is formed from a first wafer, the first wafer transferring a pattern to the flexible stamp, in which an antenna substrate is shaped into a three-dimensional contour with a second mold, in which the flexible stamp is positioned in the second mold to deform the flexible stamp into the three-dimensional contour, and in which a metallic layer on the flexible stamp is cold welded to create a set of antenna traces on the antenna substrate in accordance with the pattern. The antenna traces may then be electroplated.
