Abstract: In cases where AGP driving is applied to a CCD solid-state image sensor having a horizontal overflow drain structure, a problem arises in that the charges overflow into the second channel regions (8) from the overflow drain regions (14), and noise is superimposed on the information charges. The CCD solid-state image sensor has a plurality of first channel regions (4) that are disposed parallel to each other, overflow drain regions (14) that are disposed between neighboring first channel regions (4), a plurality of separation regions (12) that are disposed between the first channel regions (4) and overflow drain regions (14), and a plurality of first transfer electrodes (10) that are disposed parallel to each other over the plurality of first channel regions in the direction perpendicular to the first channel regions (4). In other to solve the problem described above, the CCD solid-state image sensor further comprises second channel regions (9) which are disposed in positions corresponding to the regions where the first channel regions (4) and specified first transfer electrodes (10) intersect, and which have a higher concentration than the first channel regions (4), and the overflow drain regions (14) adjacent to the second channel regions (8) have protruding parts (18) that protrude toward the second channel regions (8).

Abstract: A mixing of color that follows mixing of horizontally adjoining information charges corresponding to different colors is minimized during an operation for adding information charges of a plurality of pixels in a horizontal direction and during a high-speed horizontal transfer operation in a horizontal CCD shift register of a CCD image sensor. An impurity is used for forming barrier regions having a shallow channel potential among the barrier regions and storage regions that constitute transfer stages of the horizontal CCD shift register. The concentration of the impurity is established separately in a main portion, which is composed of transfer stages that are connected to the output ends of vertical CCD shift registers, and in a dummy portion, which connects the main portion with an output section and has a width that gradually decreases towards the output section. The barrier potential is therefore also established separately in the main portion and the dummy portion. The barrier potential is set to be high in the main portion, and the overflow of information charges into adjoining wells is minimized during the addition operation. The transfer length may be longer in the dummy portion, in which the barrier potential is limited and the fringe electric field is increased, ensuring efficient transfer during high-speed horizontal transfer.

Abstract: In an image pickup portion of a frame transfer CCD image sensor, a constitution that inhibits color mixing from occurring between light-sensitive pixels adjacent along a vertical CCD shift register channel is provided. A protrusion extending on the channel is formed at a clock wiring formed on a channel stop of the vertical CCD shift register with an wiring layer having the light-shielding property. When the protrusion portion is disposed at a boundary of light-sensitive pixels in the channel, a non-light-shielding portion generated at the boundary can be suppressed. The protrusions are disposed so as to alternately protrude from the clock wirings on both sides of the channel.

Abstract: An imaging system, capable of reducing blooming in a solid-state imaging device and improving image sensitivity, comprises an imaging section which has at least three transfer electrodes and is continuously arranged with pixels for producing information charges in response to the light from the outside, wherein the information charges are stored and transferred using potential wells formed by potentials applied to the transfer electrodes and, during image capture, one of the transfer electrodes is maintained in an ON state and at least another one of the transfer electrodes is alternately switched between an ON state and an OFF state. It is more preferable to average the amount of generated dark current under the transfer electrodes by switching the transfer electrodes between an ON state and an OFF state for image capture. This provides restraint of a difference in the amount of generated dark current between pixels, thus reducing image graininess.
