Abstract
Disclosed herein is a solid-state imaging device including: a sensor element having a plurality of pixels each having a photoelectric conversion section; and a logic element attached to the sensor element in such a manner as to be stacked on the sensor element face-to-face and provided with a pad electrode. In a stacked body of the sensor and logic elements, a pad opening is provided above the top surface of the pad electrode facing the sensor element, and a pad periphery guard ring is provided to surround the side portion of the pad opening. The pad periphery guard ring is formed by integrally filling, on the side of the pad opening, an entire trench that is at least as deep as the pad opening with a metal material.
