Patent number: 11418741Abstract: The present disclosure relates to a solid-state imaging device and an electronic device that can be provided with phase difference pixels with a lower degree of difficulty in manufacturing. Provided is a solid-state imaging device including a pixel array unit in which a plurality of pixels is two-dimensionally arrayed, in which the pixel array unit has an array pattern in which a plurality of pixel groups each including neighboring pixels of an identical color is regularly arrayed, and among the plurality of pixel groups arrayed in the array pattern, pixels configuring a light-shielded pixel group are shielded in an identical direction side from light, the light-shielded pixel group being a pixel group including pixels each being shielded in a part of a light incident side from the light. The present technology can be applied to, for example, a CMOS image sensor including pixels for phase difference detection.Type: GrantFiled: June 15, 2018Date of Patent: August 16, 2022Assignee: Sony Semiconductor Solutions CorporationInventor: Keiichiro Takahashi
