Abstract
Provided is a solid-state imaging element, a manufacturing method, and an electronic apparatus which are capable of further improving a light-blocking effect. The solid-state imaging element has a laminated structure in which a memory substrate, a logic substrate, and a sensor substrate are laminated. The solid-state imaging element includes a through electrode that connects the memory substrate and the sensor substrate in a manner passing through a semiconductor layer of the logic substrate, and a light-blocking metal film arranged in a wiring layer included in the logic substrate and provided on the sensor substrate side, where the light-blocking metal film has an opening opened so as to allow the through electrode to pass through. The solid-state imaging element further includes a contact electrode formed on a bonded surface between the logic substrate and the sensor substrate and used to connect the through electrode to the sensor substrate side.
