  • Publication number: 20230369369
    Abstract: Some implementations described herein provide pixel sensor configurations and methods of forming the same. In some implementations, one or more transistors of a pixel sensor are included on a circuitry die (e.g., an application specific integrated circuit (ASIC) die or another type of circuitry die) of an image sensor device. The one or more transistors may include a source follower transistor, a row select transistor, and/or another transistor that is used to control the operation of the pixel sensor. Including the one or more transistors of the pixel sensor (and other pixel sensors of the image sensor device) on the circuitry die reduces the area occupied by transistors in the pixel sensor on the sensor die. This enables the area for photon collection in the pixel sensor to be increased.

  • Patent number: 11810936
    Abstract: A pixel array may include air gap reflection structures under a photodiode of a pixel sensor to reflect photons that would otherwise partially refract or scatter through a bottom surface of a photodiode. The air gap reflection structures may reflect photons upward toward the photodiode so that the photons may be absorbed by the photodiode. This may increase the quantity of photons absorbed by the photodiode, which may increase the quantum efficiency of the pixel sensor and the pixel array.
