| 20090278174 | PIXEL STRUCTURE OF SOLID-STATE IMAGE SENSOR - A pixel structure of a solid-state image sensor in which residual electrons in a photodiode is reduced and which has a first-stage gate that is arranged adjacent to the photodiode and controls read-out of electrons generated in the photodiode, a second-stage gate that is adjacent to the first-stage gate on the rear stage of the gate at a predetermined gap and controls movement of electrons read out by the readout control of the first-stage gate to the plurality of the charge-storage sections, and a plurality of third-stage gates that are adjacent to the second-stage gate on the rear stage of the gate at a predetermined gap, severally arranged corresponding to the plurality of the charge-storage sections, and perform control of distributing the electrons moved by the movement control of the second-stage gate severally to the plurality of the charge-storage sections, and gradient on which electrons are moved in the first-stage gate direction is formed on the potential of the photodiode. | 11-12-2009 |
| 20090057673 | Pixel structure of solid-state image sensor - To eliminate uneven distribution of electrons caused by variation in threshold voltages of gates for distributing electrons and to have sensitivity in a long wavelength in a pixel structure of a solid-state image sensor of a charge sorting method, the structure has: a photodiode that generates electrons by photoelectric conversion; a plurality of charge-storage sections that store electrons generated in the photodiode; and a gate structure that is arranged between the photodiode and the charge-storage sections and controls transfer of electrons generated in the photodiode to the plurality of charge-storage sections, in which the gate structure is made up of plural stages of gates, and the plural stages of gates at least have: a front stage gate that is arranged adjacent to the photodiode and controls readout of electrons generated in the photodiode; and a rear stage gate that is arranged adjacent to the plurality of charge-storage sections on the rear stage of the front stage gate and performs control of distributing electrons read out by readout control of the front stage gate to the plurality of charge-storage sections. | 03-05-2009 |
