  • Publication number: 20240128289
    Abstract: The present disclosure concerns an image sensor including a plurality of pixels, each including: a doped photosensitive region of a first conductivity type extending vertically in a semiconductor substrate; a charge collection region more heavily doped with the first conductivity type than the photosensitive region, extending vertically in the substrate from an upper surface of the substrate and being arranged above the photosensitive region; and a vertical stack including a vertical transfer gate and a vertical electric insulation wall, the stack crossing the substrate and being in contact with the charge collection region, the gate being arranged on the upper surface side of the substrate and penetrating into the substrate deeper than the charge collection region.

  • Patent number: 11695028
    Abstract: A semiconductor image sensor includes a plurality of pixels. Each pixel of the sensor includes a semiconductor substrate having opposite front and back sides and laterally delimited by a first insulating wall including a first conductive core insulated from the substrate, electron-hole pairs being capable of forming in the substrate due to a back-side illumination. A circuit is configured to maintain, during a first phase in a first operating mode, the first conductive core at a first potential and to maintain, during at least a portion of the first phase in a second operating mode, the first conductive core at a second potential different from the first potential.

  • Publication number: 20200168646
    Abstract: An integrated imaging device includes a pixel having a trench that extends into the substrate. The trench is coated with an insulator and filled with a stack including a first polysilicon region and a second polysilicon region. The first and second polysilicon regions are separated from each other by a layer of insulating material. The first polysilicon region may form a gate electrode of a vertical transistor and the second polysilicon region may form an electrode of a capacitor.
