Abstract:
1. A solid state imaging device comprising: a semiconductor layer having multiple photoelectric conversion elements arranged in a two-dimensional array; a light shielding portion that is provided in the semiconductor layer, and includes a light shielding member having an interface with the semiconductor layer, the interface being covered by an insulating film, wherein the light shielding portion includes: a light shielding region that is provided in the semiconductor layer on the side close to a light receiving surface of a photoelectric conversion element of the multiple photoelectric conversion elements for shielding light incident on the photoelectric conversion element from a specific direction; and an element isolation region that is provided to project in a depth direction of the semiconductor layer from the light shielding region toward a portion between the multiple photoelectric conversion elements in order to electrically and optically isolate the multiple photoelectric conversion elements from one another, wherein the light shielding region is provided on a position covering a part of the light receiving surface of the photoelectric conversion element that outputs a signal charge for detecting a focus by a pupil division phase difference detection system, out of the multiple photoelectric conversion elements.
