Abstract:
A solid-state imaging device comprising:a plurality of photoelectric conversion elements disposed on a semiconductor substrate; first and second charge transfer registers disposed on said semiconductor substrate, for transferring signal charges generated by said plurality of photoelectric conversion elements; first and second signal charge detectors disposed on said semiconductor substrate, each of said first and second signal charge detectors being disposed in the vicinity of one edge of each of said first and second charge transfer registers, respectively; and first and second transistors disposed on said semiconductor substrate, wherein: said first and second charge transfer registers transfer the signal charges in opposite directions; said first and second signal charge detectors receive the signal charges from said first and second charge transfer registers, respectively, and output voltages having a magnitude in accordance with the amount of charge; each of said first and second transistors includes a gate into which the voltage output from said first or second signal charge detector is input, a source, and a drain, the source and the drain being formed adjacent to the gate; and said first signal charge detector, the source, the drain, and the gate of said first transistor are almost congruent to said second signal charge detector, the source, the drain, and the gate of said second transistor, respectively, when viewed from above, said first signal charge detector, the source, the drain, and the gate of said first transistor being overlaid almost completely on said second signal charge detector, the source, the drain, and the gate of said second transistor, respectively, by a translational movement.
