Solid-state imaging device, solid-state imaging device manufacturing method, and electronic device

Abstract

Provided is a solid-state imaging device capable of further improving reliability of a solid-state imaging device and further reducing manufacturing cost. Provided is a solid-state imaging device including a second semiconductor substrate provided with a photoelectric conversion unit and a second element, a second insulating layer, a first semiconductor substrate provided with a first element, and a first insulating layer arranged in this order from a light incident side, and including a groove formed on the first semiconductor substrate, in which the groove has a first side wall and a second side wall, and a part of at least one side wall of the first side wall or the second side wall extends in an oblique direction with respect to a surface of the first semiconductor substrate on the light incident side.
