  • Patent number: 11942496
    Abstract: A digital image sensor package includes an image sensor substrate and a glass covering. The image sensor substrate carries photodiodes. The glass covering has a bottom surface, a top surface opposite the bottom surface, and a sidewall delimiting a perimeter edge of the glass covering. The glass covering overlies the photodiodes. A surface area of the top surface of the glass covering is greater than a surface area of the bottom surface of the glass covering such that the sidewall is anti-perpendicular to the top and bottom surfaces of the glass.

  • Patent number: 11502029
    Abstract: The present disclosure provides devices and methods in which a semiconductor chip has a reduced size and thickness. The device is manufactured by utilizing a sacrificial or dummy silicon wafer. A recess is formed in the dummy silicon wafer where the semiconductor chip is mounted in the recess. The space between the dummy silicon wafer and the chip is filled with underfill material. The dummy silicon wafer and the backside of the chip are etched using any suitable etching process until the dummy silicon wafer is removed, and the thickness of the chip is reduced. With this process, the overall thickness of the semiconductor chip can be thinned down to less than 50 ?m in some embodiments. The ultra-thin semiconductor chip can be incorporated in manufacturing flexible/rollable display panels, foldable mobile devices, wearable displays, or any other electrical or electronic devices.

  • Publication number: 20220352057
    Abstract: A substrate includes electrically-conductive tracks. A semiconductor chip is arranged on the substrate and electrically coupled to selected ones of the electrically-conductive tracks. Containment structures are provided at selected locations on the electrically-conductive tracks, where the containment structures have respective perimeter walls defining respective cavities. Each cavity is configured to accommodate a base portion of a pin holder. These pin holders are soldered to the electrically-conductive tracks within the cavities defined by the containment structures. Each containment structure may be formed by a ring of resist material configured to receive solder and maintain the pin holders in a desired alignment position.

  • Patent number: 8937774
    Abstract: A method comprises depositing an optical filter layer on a glass wafer, then cutting the wafer into dice. The dice are positioned on a carrier and encapsulated in a molding compound to form a reconstituted wafer, and the wafer is back-ground and polished. Lens faces are positioned on opposing surfaces of the glass dice and spacers are positioned on one side of the wafer. The wafer is then cut into lens modules, each having two side-by-side lenses with an opaque molding compound barrier between. The individual modules are attached to devices that require dual lenses, such as, e.g., proximity sensors that use a light source and a light receiver or detector.
