  • Publication number: 20240297202
    Abstract: To prevent leakage of incident light to a charge holding unit of an imaging element. The pixel includes a photoelectric conversion unit disposed on a side of the light receiving face of the semiconductor substrate, a charge holding unit disposed on a side different from the light receiving face of the semiconductor substrate, and a charge transfer unit that transfers a charge to the charge holding unit, and is configured to have a rectangular shape in a light receiving face view. The charge holding unit light shielding film is configured to have a band shape adjacent to three sides including a first side that is one of the sides of the rectangle and parallel to the first side in a light receiving face view, is adjacent to a semiconductor region including the charge transfer unit in a light receiving face view, and is disposed in the pixel between the photoelectric conversion unit and the charge holding unit to shield incident light.

  • Publication number: 20240234459
    Abstract: An imaging device of an embodiment of the disclosure includes: a semiconductor substrate in which multiple sensor pixels are arranged in array, the semiconductor substrate having a first surface serving as a light incident surface and a second surface opposed thereto; a photoelectric conversion section provided on a side of the first surface inside the semiconductor substrate and generating electric charge corresponding to a light reception amount by photoelectric conversion; a charge-holding section provided on a side of the second surface inside the semiconductor substrate and holding the electric charge transferred from the photoelectric conversion section; a first light-blocking section extending in an in-plane direction of the semiconductor substrate between the photoelectric conversion section and the charge-holding section; and a light-condensing optical system provided on the side of the first surface and condensing incident light on a substantial geometric center of the first light-blocking section i
