ABSTRACT:
A solid state imaging device has a semiconductor substrate with photodiodes and charge transfer sections formed thereon, transfer electrodes formed on the charge transfer sections across an insulating layer, and a light shielding layer to protect the charge transfer sections from light. The light shielding layer has openings to correspond the positions of the photodiodes. Disposed above the openings of the light shielding layer are microlenses, and a converging structure such as a converging lens is provided inside each opening. Incident light rays from the microlens are focused toward the photodiode effectively by the converging lens.
