  • Patent number: 7023031
    Abstract: A CMOS image sensor formed on a chip has a ROM disposed on the chip for recording pixel defect locations, chip-by-chip variations such as bias, and other manufacturing production data. Testing results and repair solutions are written to the ROM after production testing. A simple circuit for writing information to the ROM also is provided on the CMOS chip. During operational use of the image sensor, data is read from the on-chip ROM to assist in compensating for manufacturing process variations.

  • Patent number: 7012645
    Abstract: A pixel sensor that provides image sensing under radiation or space environment is disclosed. The pixel sensor includes a readout circuit and a first reset circuit. The readout circuit converts optical image signals to electronic signals, and includes p-type transistors and an n-type photosensitive element. The first reset circuit is configured to provide a reset level for a pixel output, and also includes p-type transistors. The use of p-type transistors and n-type photosensitive element provides radiation hardness without any radiation protective enclosure.

  • Publication number: 20050280991
    Abstract: This invention relates to a fast mountable screw assembly for CPU heat sink, comprising a base unit, a fan unit and a heat fin unit. There are hollow bolt holes on four corners of the base unit and each bolt hole is filled with a fastener for a screw to pass through and being locked on the base unit plate. The base unit links to the heat fan unit at one side and the heat fin unit at other side, and a wind conduit is connected between the base unit and the heat fin unit. The specific design is the fastener which has a spring, and the center hole of the fastener will accept the screw. The bottom of the fastener will be punched with a special tool to be pivoted on the base unit, so the fastener is moveable but never falling off. In practice, this heat sink is easy, fast and convenient to assemble with components interchangeable to gain the greatest economical benefit.

  • Publication number: 20050236694
    Abstract: In the preferred embodiment, a gate dielectric and an electrode are formed on a substrate. A pair of spacers is formed along opposite sidewalls of the gate electrode and the gate dielectric. Spacers are preferably formed of SiCO based material or SiCN based material. The source and drain are then formed. A contact etch stop (CES) layer is formed on the source/drain regions and the spacers. The CES layer is preferably formed of SiCO based material or SiCN based material. An Inter-Level Dielectric (ILD) is then formed on the CES layer.

  • Publication number: 20050127432
    Abstract: A method of manufacturing a semiconductor device, wherein a gate structure is formed over a substrate, an interconnect layer is formed over the gate structure and the substrate, and a cap layer is formed over the interconnect layer. The interconnect layer and the cap layer are then planarized to form a substantially planar surface. A mask layer, such as an oxide mask layer, is formed over the planarized portions of the interconnect layer, and the planarized cap layer and portions of the interconnect layer are removed by etching around the mask layer.

  • Patent number: 6518907
    Abstract: An A/D conversion system for an image sensor. The image sensor acquires image signals, and outputs them to a plurality of sample and hold circuits. The sample and hold circuits are grouped and are commonly actuated, in order to simplify the control circuit. Once the signals are in the sample and hold circuits, the next clock cycle commonly actuates a plurality of A/D converters which commonly convert all of those signals. During that same clock cycle, another set of sample and hold circuits may be actuated.
