  • Publication number: 20220238569
    Abstract: An image sensor includes a substrate. A pixel separation pattern defines a plurality of unit pixels inside the substrate. A first photoelectric conversion unit and a second photoelectric conversion unit are arranged inside each of the plurality of unit pixels in a first direction. A plurality of microlenses is disposed on the substrate to correspond to each of the plurality of unit pixels. A region separation pattern is disposed in the substrate between the first photoelectric conversion unit and the second photoelectric conversion unit. The region separation pattern extends in a second direction intersecting the first direction, is directly connected to the pixel separation pattern, and has a zigzag shape or a wavy shape in a plan view.

  • Patent number: 11139329
    Abstract: The present disclosure relates to a solid-state imaging element, a manufacturing method, and an electronic apparatus, in which irregular reflection of light inside a solid-state imaging element package can be suppressed. In the solid-state imaging element, a plurality of pixels is planarly arranged, a connection portion utilized for connection to the outside is provided on a more outer side than an imaging region, and an open portion that is opened up to the connection portion from a light incident surface side of the imaging region where light is incident is formed. Additionally, a plurality of protruding portions periodically arranged is formed on a counterbore surface that is a surface inside the open portion excluding the connection portion. The present technology can be applied to, for example, a back-illuminated type or layered CMOS image sensor.
