Patent ID: 8884347

Claim:
A method of manufacturing a photoelectric conversion device, comprising: a first step of forming a plurality of photoelectric conversion regions on a surface on one side of a semiconductor wafer; a second step of preparing a light-blocking wafer having insertion openings, the insertion openings corresponding respectively to the photoelectric conversion regions, wherein the light-blocking wafer is a wafer formed from carbon or resin; a third step of bonding the one-side surface of the semiconductor wafer and a surface on the opposite side to a surface on the one side of the light-blocking wafer to each other, in such a manner that the photoelectric conversion regions and the insertion openings correspond to each other, to form a bonded wafer body without an optical element; a step of inserting an optical element into the insertion openings of the bonded wafer body; and a step of bonding a reinforcement plate to a surface on the opposite side to the one-side surface of the semiconductor wafer or/and to the one-side surface of the light-blocking wafer, prior to the third step, a fourth step of dividing the bonded wafer body in peripheries of the photoelectric conversion regions, to obtain bonded-body chips each having the photoelectric conversion region.
