Abstract:
1. An imaging system comprising: a light guiding member supported on a circuit substrate so as to be capable of lighting an object; an optical image-forming member arranged on the circuit substrate so as to have an optical axis of the optical image-forming member parallel to the circuit substrate, arranged on the circuit substrate so as to be able to receive reflected light from the object, that emits the reflected light in an oblique direction with respect to a surface of the circuit substrate, and forms an image at a predetermined distance position; and a solid-state imaging device including a light receiving surface that is oblique with respect to the surface of the circuit substrate, and being mounted on the surface of the circuit substrate so as to have the light receiving surface arranged at the position where the image is formed from the reflected light of the object by the optical image-forming member, the solid-state imaging device including a silicon substrate including the light receiving surface, the light receiving surface being a plane surface of the silicon substrate; a first impurity region formed on a surface of the silicon substrate; a second impurity layer formed at the light receiving surface within the surface of the first impurity region, and that configures a photodiode by forming a pn junction with the first impurity region; and an electrode formed via an oxide film on the surface of the first impurity region excluding the light receiving surface.
