  • Patent number: 11062679
    Abstract: An imaging device includes a first pixel. The first pixel includes a first photoelectric conversion region disposed in a first substrate and that converts incident light into first electric charges. The first pixel includes a first readout circuit including a first converter that converts the first electric charges into a first logarithmic voltage signal. The imaging device includes at least one bonding pad on the first substrate and in electrical contact with the first converter. The at least one bonding pad overlaps at least part of the first pixel.

  • Publication number: 20210168316
    Abstract: An imaging device includes a first pixel including a first photoelectric conversion region disposed in a first substrate and that converts incident light into first electric charges, and a first readout circuit including a first converter that converts the first electric charges into a first logarithmic voltage signal. The first converter includes a first transistor coupled to the first photoelectric conversion region and a second transistor coupled to the first transistor. The imaging device includes a wiring layer on the first substrate and includes a first level of wirings arranged in a first arrangement overlapping the first photoelectric conversion region and in a second arrangement overlapping the first and second transistors, the second arrangement being different than the first arrangement.

  • Publication number: 20210168314
    Abstract: An imaging device with a plurality of image sensing pixels and a plurality of event detection pixels is provided. Each image sensing pixel includes a photoelectric conversion element and an imaging signal generation readout circuit. The image sensing readout circuit can be shared by a plurality of photoelectric conversion elements. Each event detection pixel includes a photoelectric conversion element and an event detection readout circuit. The event detection readout circuit can be shared by a plurality of photoelectric conversion elements. In addition, the photoelectric conversion element of an event detection pixel can be selectively connected to a shared imaging signal generation readout circuit. The number of image sensing pixels is greater than the number of event detection pixels. In addition, the area of a photoelectric conversion element of an event detection pixel can be greater than the area of a photoelectric conversion element of an image sensing pixel.

  • Publication number: 20210084246
    Abstract: An imaging device includes a plurality of unit pixels or pixels, with each pixel separated from every other unit pixel by an isolation structure. Each unit pixel includes a photoelectric conversion unit, a pixel imaging signal readout circuit, and an address event detection readout circuit. A first transfer transistor selectively connects the photoelectric conversion unit to the pixel imaging signal readout circuit, and a second transfer transistor selectively connects the photoelectric conversion unit to the address event detection readout circuit. The photoelectric conversion unit, the pixel imaging signal readout circuit, the address event detection readout circuit, and the first and second transfer transistors for a given pixel are located within a pixel area defined by the isolation structure. The isolation structure may be in the form of a full thickness dielectric trench isolation structure.

  • Publication number: 20210074745
    Abstract: An imaging device includes a plurality of unit pixels disposed into pixel groups that are separated from one another by isolation structures. Unit pixels within each pixel group are separated from one another by isolation structures and share circuit elements. The isolation structures between pixel groups are full thickness isolation structures. At least a portion of the isolation structures between unit pixels within a pixel group are deep trench isolation structures.
