Abstract
A backside-illuminated imaging device, which performs imaging by illuminating light from a back side of a semiconductor substrate to generate electric charges in the semiconductor substrate based on the light and reading out the electric charges from a front side of the semiconductor substrate, is provided and includes: a back-side layer including an back-side element on the back side of the semiconductor substrate; a front-side layer including an front-side element on the front side of the semiconductor substrate; a support substrate above the front-side layer; a spacer, one end of which comes in contact with the front-side layer and the other end of which comes in contact with the support substrate, to form a space having a uniform distance between the semiconductor substrate and the support substrate; and an adhesive filled in at least a part of the space between the surface-side element formation layer and the support substrate.
