ABSTRACT:
In a solid-state image pickup device comprising a plurality of photoelectric converting sections, vertical charge transfer sections each comprising first and second vertical charge transfer electrodes (26a, 26b) and a vertical charge transfer region (23), and power feeding sections, each of the power feeding sections is divided into first through fourth metal wires (28a, 28b, 28c, 28d). The first through the third metal wires (28a, 28b, 28c) are formed in a first layer of a conductive film. The fourth metal wire (28d) is formed in a second layer of the conductive film. The first and the third metal wires (28a, 28c) are alternately connected to the first vertical charge transfer electrodes (26a) via contact holes (27). The second and the fourth metal wires (28b, 28d) are alternately connected to the second vertical charge transfer electrodes (26b) via contact holes (27). The first through the fourth metal wires (28a, 28b, 28c, 28d) are applied with first through fourth clock pulse signals (.phi.1, .phi.2, .phi.3, 100 4), respectively, which are different in phase from one another. The first and the third metal wires (28a, 28c) only light-shield areas between the photoelectric converting sections and vertical charge transfer regions.
