Abstract
The present disclosure provides a method of manufacturing a photoelectric conversion device, including, 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, 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 to form a bonded wafer body, and 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.
