Abstract
The present disclosure relates to a light reception element and an electronic device that make it possible to achieve better performance. Provided is a SPAD element including an avalanche multiplication region provided at a junction surface between an N-type diffusion layer and a P-type diffusion layer provided on a side of a sensor substrate opposite from a light reception surface of the sensor substrate, a hole accumulation layer provided so as to surround a lateral surface and a light reception surface of a well provided in the sensor substrate, a pinning layer provided outside the hole accumulation layer, and an in-pixel trench structure provided in a pixel region, the pinning layer being formed all over an outer peripheral surface of the in-pixel trench structure. The present technology is applicable to, for example, a distance image sensor that performs time-of-flight (ToF)-based distance measurement.
