Abstract: The present invention can be applied to a CMOS image sensor in which each pixel circuit of an active pixel sensor array includes a photoelectric conversion element for converting input light into electricity and a switch transistor for controlling the supply of a reset voltage for resetting the photoelectric conversion element to a predetermined voltage, to the photoelectric conversion element. The CMOS image sensor comprises a control circuit for assigning a control signal applied to a control electrode of the switch transistor. The control circuit outputs a first voltage much higher than a supply voltage of the CMOS image sensor so as to make an ON resistance of the switch transistor sufficiently small in the first part of a reset period of the photoelectric conversion element and outputs a second voltage lower than a supply voltage of the CMOS image sensor in the latter part of a reset period of the photoelectric conversion element.

Abstract: First diffusion region constituting a photodiode in each pixel stores carriers generated according to incident light. Second diffusion region is formed at a surface of the first diffusion region to cover a peripheral part of the first diffusion region. In the peripheral part of the first diffusion region, crystal defects tend to occur by a process of forming an isolation region and a gate electrode, so that dark current noise tends to occur. The second diffusion region functioning as a protection layer prevents crystal defects in a manufacturing process. The second diffusion region isn't formed on a center of the surface of the first diffusion region where crystal defects don't tend to occur. In the first diffusion region where the second diffusion region isn't formed, the thickness of a depletion layer increases, which improves light detection sensitivity. This improves detection sensitivity of the photodiode without increasing the dark current noise.
