  • Publication number: 20060273353
    Abstract: An image sensor includes a unit cell having a plurality of pixels; the unit cell comprising an amplifier input transistor that is shared by the plurality of pixels; a plurality of floating diffusions that are joined by a floating diffusion interconnect layer and are connected to the amplifier input transistor; and an interconnect layer which forms an output signal wire which shields the floating diffusion interconnect layer.

  • Publication number: 20060092296
    Abstract: A method for lowering dark current in an image sensor pixel, the method includes the steps of providing a photosensitive area for receiving incident light which is converted into a charge; providing a gate for transferring charge from the photosensitive area; wherein the gate is held at a voltage which will accumulate majority carriers at a semiconductor-dielectric interface during integration for the photosensitive area. Alternatively, a potentail profile can be provided under the gate to drain the dark current away from the photogeneration diffusion.

  • Publication number: 20050045980
    Abstract: An image sensor includes a plurality of pixels; a color filter pattern spanning at least a portion of the pixels, wherein the color filter pattern forms a color filter kernel having colors in a predetermined arrangement; and a mechanism for controlling integration time of the pixels, wherein the integration time of the plurality of pixels is spatially variant in a pattern that is correlated with the color filter array kernel.

  • Publication number: 20050012836
    Abstract: An image sensor includes: (a) a plurality of light measuring elements arranged in an array and at least a portion of the elements have a color filter mated with the light receiving elements which permits selective color reception by the light measuring elements; (b) a plurality of floating diffusions respectively mated with the plurality of light receiving elements; and c) an output structure electrically connected to two or more of the floating diffusions; wherein the at least two light receiving elements receiving the same color are transferred to the output structure substantially simultaneously.
