Abstract:
A solid-state image pick-up device comprising:a plurality of light receiving portions which are arranged in a line direction at a predetermined pitch and in a row direction perpendicular thereto on a semiconductor substrate, said plurality of light receiving portions being arranged such that a pixel, which is corresponding to a light receiving portion, and another pixel, which is adjacent to said pixel and corresponding to another light receiving portion, being relatively shifted by half a pixel pitch in the line direction and the row direction; a vertical charge transfer portion having a vertical charge transfer path which adjoins the light receiving portions extending in the row direction, in which the electric charge generated in the light receiving portions is transferred, and charge transfer electrodes composed of polysilicon electrodes extending in the line direction so as to cover the vertical charge transfer path and supply a transfer pulse for controlling a potential of the vertical charge transfer path; a metal wiring which is provided corresponding to each electrode in the upper portion of the charge transfer electrodes, said metal wiring extending along the vertical charge transfer portion in the row direction; and a contact portion by which each of the polysilicon electrodes and the metal wiring are electrically connected.
