Abstract
[Object] To provide a solid-state imaging device and an electronic apparatus with further improved performance. [Solution] A solid-state imaging device including: a first substrate on which a pixel unit is formed, and a first semiconductor substrate and a first multi-layered wiring layer are stacked; a second substrate on which a circuit having a predetermined function is formed, and a second semiconductor substrate and a second multi-layered wiring layer are stacked; and a third substrate on which a circuit having a predetermined function is formed, and a third semiconductor substrate and a third multi-layered wiring layer are stacked. The first substrate, the second substrate, and the third substrate are stacked in this order. The pixel unit has pixels arranged thereon. The first substrate and the second substrate are bonded together with the first multi-layered wiring layer and the second semiconductor substrate opposed to each other. The solid-state imaging device includes a first coupling structure for electrically coupling a circuit of the first substrate and the circuit of the second substrate to each other. The first coupling structure includes a via in which one through ho…
