  • Publication number: 20090166518
    Abstract: An image sensor pixel that includes a photoelectric conversion unit supported by a substrate and an insulator adjacent to the substrate. The pixel includes a light guide that is located within an opening of the insulator and extends above the insulator such that a portion of the light guide has an air interface. The air interface improves the internal reflection of the light guide. Additionally, the light guide and an adjacent color filter are constructed with a process that optimizes the upper aperture of the light guide. These characteristics of the light guide eliminate the need for a microlens.

    Abstract: A structure includes a semiconductor die that has an arrangement of die pads on a surface of the semiconductor die. A first row of die pads consists of a first group of four die pads and run in a first direction. A second row of die pads are adjacent to the first row and consist of a second group of four die pads running in the first direction. The second row begins at a first offset in the first direction from where the first row begins. A third row of die pads are adjacent to the second row and comprise a third group of four die pads that run in the first direction. The third row begins at a second offset in the first direction from where the second row begins. This allows for relatively easy access to all of the die pads.

  • Patent number: 7549090
    Abstract: An apparatus, program product and method propagate errors detected in an IO fabric element from an IO fabric that is used to couple a plurality of endpoint IO resources to processing elements in a computer. In particular, such errors are propagated to the endpoint IO resources affected by the IO fabric element in connection with recovering from the errors in the IO fabric element. By doing so, a device driver or other program code used to access each affected IO resources may be permitted to asynchronously recover from the propagated error in its associated IO resource, and often without requiring the recovery from the error in the IO fabric element to wait for recovery to be completed for each of the affected IO resources. In addition, an IO fabric may be dynamically configured to support both recoverable and non-recoverable endpoint IO resources.

  • Publication number: 20090098717
    Abstract: The present invention is related to methods and apparatus that allow a chalcogenide glass such as germanium selenide (GexSe1-x) to be doped with a metal such as silver, copper, or zinc without utilizing an ultraviolet (UV) photodoping step to dope the chalcogenide glass with the metal. The chalcogenide glass doped with the metal can be used to store data in a memory device. Advantageously, the systems and methods co-sputter the metal and the chalcogenide glass and allow for relatively precise and efficient control of a constituent ratio between the doping metal and the chalcogenide glass. Further advantageously, the systems and methods enable the doping of the chalcogenide glass with a relatively high degree of uniformity over the depth of the formed layer of chalcogenide glass and the metal. Also, the systems and methods allow a metal concentration to be varied in a controlled manner along the thin film depth.

  • Publication number: 20090093075
    Abstract: A method for the separation of multiple dies during semiconductor fabrication is described. On an upper surface of a semiconductor wafer containing multiple dies, metal layers are deposited everywhere except where a block of stop electroplating material exists. The stop electroplating material is obliterated, and a barrier layer is formed above the entire remaining structure. A sacrificial metal element is added above the barrier layer, and then the substrate is removed. After the semiconductor material between the individual dies is eradicated, any desired bonding pads and patterned circuitry are added to the semiconductor surface opposite the sacrificial metal element, a passivation layer is added to this surface, and then the sacrificial metal element is removed. Tape is added to the now exposed barrier layer, the passivation layer is removed, the resulting structure is flipped over, and the tape is expanded to separate the individual dies.
