Abstract:
1. A method of manufacturing a backside-illuminated imaging device that 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, the method comprising: forming a front-side layer including a front-side element on a front side of the semiconductor substrate; forming a pattern of protrusion portions at respective specific positions of a support substrate to come in physical contact with the support substrate that is for supporting the semiconductor substrate; adhering the semiconductor substrate to the support substrate by filling with an adhesive at least a part of a space formed by the protrusion portions between the front-side layer and the support substrate in a state where the protrusion portions come in physical contact with the front-side layer; and forming a back-side layer including a back-side element on a back side of the semiconductor substrate in a state where the semiconductor substrate and the support substrate are adhered to each other.
