  • Image sensing device having multiple transfer gate structure
    Patent number: 11784200
    Abstract: An image sensing device includes a photoelectric conversion element configured to generate photocharges in response to incident light, a floating diffusion configured to temporarily store the photocharges generated by the photoelectric conversion element, and a transfer gate configured to transmit the photocharges generated by the photoelectric conversion element to the floating diffusion region. The transfer gate includes a main transfer gate disposed to overlap a center section of the photoelectric conversion element and configured to operate in response to a first transmission signal, and a sub transfer gate disposed to overlap a boundary region of the photoelectric conversion element and configured to operate in response to a second potential level different from the first potential level.
    Type: Grant

  • IMAGE SENSOR
    Publication number: 20210343765
    Abstract: An image sensing device is provided to include a first photoelectric conversion element and a second photoelectric conversion element that are arranged adjacent to each other; a first isolation region located between the first and second photoelectric conversion elements and configured to receive a voltage to generate an electric field to attract photocharges from the first or second photoelectric conversion element; and a second isolation region separated from the first isolation region, the second isolation region located between the first and second photoelectric conversion elements and structured to include an insulation material to block photocharges from moving between the first and second photoelectric conversion elements.
