Claim Text:
1. An image pickup device, comprising: a semiconductor substrate having a main surface; a photoelectric conversion part that is formed in a predetermined region in the semiconductor substrate and converts entering light into a charge; a gate electrode of a transfer transistor that is formed over a surface of the semiconductor substrate and transfers the charge generated in the photoelectric conversion part; a sidewall insulating film that covers a side wall face of the gate electrode and that includes a part extending from a part covering the side wall face and covering a surface of the photoelectric conversion part; an interlayer insulating film formed so as to cover the sidewall insulating film; and a waveguide that is formed so as to penetrate through the interlayer insulating film and to reach the sidewall insulating film, and guides light to the photoelectric conversion part.
