摘要： A noise reduction circuit includes a plurality of electric charge accumulating sections and a plurality of switching sections. In the noise reduction circuit, electric charge in an amount corresponding to a signal containing a noise is accumulated in each of the electric charge accumulating sections, and thereafter the switching sections are turned on to connect the electric charge accumulating sections in parallel or in series with each other, thereby outputting a signal corresponding to the average of, or the sum total of, the amounts of electric charge accumulated in the respective electric charge accumulating sections.

摘要： A solid-state imaging device includes a color filter that selectively transmits incoming light. The color filter includes two λ/4 multilayer films, and an insulation layer sandwiched between the two λ/4 multilayer films. Here, each of the λ/4 multilayer films is constituted by a plurality of dielectric layers, and the optical thickness of the insulation layer is not λ/4. Since this color filter has a smaller thickness, the solid-state imaging device has a smaller size.

摘要： An imaging element includes a photoelectric conversion element, a readout transistor, an accumulated element, a detection transistor, and a reset transistor. The readout transistor reads a signal charge when a gate potential to be supplied to the gate terminal is changed from a first state to a second state. The detection transistor detects a voltage signal after the gate potential to be supplied to the gate terminal of the readout transistor is changed from the second state to the first state. A reset potential supplied from the reset transistor to the accumulated element has an intermediate potential between the gate potential in the first state that is supplied to the gate terminal of the readout transistor and a predetermined VDD potential.

摘要： With the use of the MOS-type solid-state imaging device, it is possible, by extending the period during which the VDD voltage rises from Low level to High level, that the gate voltage of the resetting unit does not fluctuate to have a positive electric potential due to the coupling capacitance between the VDD power and the gate of the resetting unit, unlike the conventional case. Consequently, the electrons necessary for rendering the accumulation unit non-selectable do not flow from the accumulation unit to the VDD power. This prevents the level of the electric potential in the accumulation unit of non-selectable row from becoming positive. Also, the detecting unit is not switched on, which prevents the error of selecting a non-selectable row.

摘要： A method for manufacturing a solid-state imaging device includes forming a transfer channel portion and a light-receiving portion in a silicon substrate; forming a silicon oxide film on the silicon substrate; forming a silicon nitride film on the silicon oxide film, the silicon nitride film acting as a gate insulating film together with the silicon oxide film above the transfer channel portion and acting as an anti-reflection film above the light-receiving portion; forming a protection film on the silicon nitride film; forming a polysilicon film above the silicon nitride film via the protection film at least above the light-receiving portion; and etching the polysilicon film so as to form a transfer electrode above the transfer channel portion. The etching of the polysilicon film is carried out so that the polysilicon film is removed above the light-receiving portion while the protection portion remains.

Here, the scan timing generation unit and the switch unit, and the external output timing unit and the switch unit control the readout and the output of the pixel signals, respectively, so that a time period required for the readout of the pixel signals from the capacitance element to the signal line is longer than a time period required for the output of the pixel signals from the signal line to the common signal line.
