Patent ID: 11769774

Abstract:
The present technology relates to a solid-state imaging device and an electronic device for increasing the degree of freedom regarding arrangement of transistors. Provided are a photoelectric conversion unit, a trench penetrating a semiconductor substrate in a depth direction and formed between the photoelectric conversion units respectively formed in adjacent pixels, and a PN junction region configured by a P-type region and an N-type region on a sidewall of the trench, in which a part of sides surrounding the photoelectric conversion unit includes a region where the P-type region is not formed or a region where the P-type region is thinly formed. The PN junction region is formed on at least one side of four sides surrounding the photoelectric conversion unit, and the P-type region is not formed on the remaining sides. The present technology can be applied to, for example, a back-illuminated-type CMOS image sensor.
