  • Publication number: 20240038791
    Abstract: The present technology relates to a solid-state imaging device and an electronic apparatus capable of improving the accuracy of phase difference detection while suppressing degradation of a picked-up image. There is provided a solid-state imaging device including: a pixel array unit, a plurality of pixels being two-dimensionally arranged in the pixel array unit, a plurality of photoelectric conversion devices being formed with respect to one on-chip lens in each of the plurality of pixels, a part of at least one of an inter-pixel separation unit formed between the plurality of pixels and an inter-pixel light blocking unit formed between the plurality of pixels protruding toward a center of the corresponding pixel in a projecting shape to form a projection portion. The present technology is applicable to, for example, a CMOS image sensor including a pixel for detecting the phase difference.

  • Publication number: 20220328536
    Abstract: An imaging device (11) includes a plurality of photoelectric converters, a separation portion (22, 23), and a plurality of elements. The photoelectric converter is provided to a semiconductor substrate. The separation portion is provided between pixels (21Gr, 21Gb, 21R, 21B) each including the photoelectric converter, the separation portion extending up to a specified depth from a light entrance surface of the semiconductor substrate, the light entrance surface being on a side on which light enters the semiconductor substrate. The element is provided on an element forming surface that is on a side opposite to the side of the light entrance surface. A first depth is deeper than a second depth, the first depth being a depth of the separation portion (22) provided in a region in which the element is provided, the second depth being a depth of the separation portion (23) provided in a region in which the element is not provided.
