Patent ID: 7400023

Claim:
A photoelectric converting film stack type solid-state image pickup device comprising: a semiconductor substrate in which a signal readout circuit is formed; a plurality of photoelectric converting films stacked above the semiconductor substrate, said plurality of photoelectric converting films comprising a first photoelectric converting film and a second photoelectric converting film; pixel electrode films corresponding to pixels; and vertical conductor lines each connected to the signal readout circuit of the semiconductor substrate and extending up to corresponding pixel electrode films, wherein each of the photoelectric converting films is sandwiched between a common electrode film and one of the pixel electrode films, wherein each of the vertical conductor lines is connected to the corresponding pixel electrode films so that photo-charges generated in the photoelectric converting films are taken out through the pixel electrode films, and wherein the common electrode film for the first photoelectric converting film is used also as the common electrode film for the second photoelectric converting film, the first photoelectric converting film is stacked below the common electrode film, and the second photoelectric converting film is stacked above the common electrode film.
