  • Patent number: 11948954
    Abstract: An electrode controls transmittance of a blocking layer over a photodiode of a pixel sensor (e.g., a photodiode of a small pixel detector) by changing oxidation of a metal material included in the blocking layer. By using the electrode to adjust transmittance of the blocking layer, pixel sensors for different uses and/or products may be produced using a single manufacturing process. As a result, power and processing resources are conserved that otherwise would have been expended in switching manufacturing processes. Additionally, production time is decreased (e.g., by eliminating downtime that would otherwise have been used to reconfigure fabrication machines.

  • Patent number: 11942364
    Abstract: In some embodiments, the present disclosure relates to a method of forming an interconnect. The method includes forming an etch stop layer (ESL) over a lower conductive structure and forming one or more dielectric layers over the ESL. A first patterning process is performed on the one or more dielectric layers to form interconnect opening and a second patterning process is performed on the one or more dielectric layers to increase a depth of the interconnect opening and expose an upper surface of the ESL. A protective layer is selectively formed on sidewalls of the one or more dielectric layers forming the interconnect opening. A third patterning process is performed to remove portions of the ESL that are uncovered by the one or more dielectric layers and the protective layer and to expose the lower conductive structure. A conductive material is formed within the interconnect opening.

  • Publication number: 20230293185
    Abstract: A novel shape memory polymer (SMP)-based device for surgical treatment of an intracorporeal defect (e.g., a void or anomaly) such as an intracranial aneurysm or fistula. In at least one non-limiting embodiment, the SMP device is a 3D-printed SMP material sized to specifically fit and thus occlude an intracranial aneurysm (ICA). The SMP device may be delivered to the intracorporeal defect via a catheter having a heating mechanism wherein the SMP device is raised above its glass transition temperature as it is deployed, causing the SMP device to return to its permanent shape after it is deployed into the intracorporeal defect. SMP device delivery systems that include the SMP devices, as well as methods of making and using the devices and systems, are also disclosed.

  • Patent number: 9779288
    Abstract: A method for identifying unknown third parties appearing within video call data based on generated image characteristics data. A user's computing device and a participant computing device may exchange and render video call data in which the user's computing device may display the unknown third-party. The user's computing device may generate image characteristics data based on selected imagery. The user's computing device may compare the image characteristics data to stored contact information on the user's computing device to find a match, and may transmit the image characteristics data to the participant computing device for comparison with local stored information stored. The participant computing device may transmit a report message to the user's computing device indicating whether a match is found. In an embodiment, a server may transmit the facial data to other devices for comparison. In another embodiment, the user's computing device may request contact information from participant computing devices.

  • Patent number: 6541871
    Abstract: A method for fabricating a stacked chip package comprises the steps of: (a) attaching a first semiconductor chip to an upper surface of a substrate through a first adhesive layer; (b) partially curing the first adhesive layer such that it gels but does not harden; (c) attaching a second semiconductor chip to the first semiconductor chip through a second adhesive layer; (d) curing the first and second adhesive layer; (e) electrically coupling the first and second semiconductor chips to a structure for making external electrical connection provided on the substrate; and (f) forming a package body over the first semiconductor chip, the second semiconductor chip, and a portion of the upper surface of the substrate. Since the first and second adhesive layers may be cured in one single step, the cycle time may be reduced thereby cutting down the production cost.
