Abstract: An imaging device having a semiconductor substrate including: a semiconductor region including an impurity of a first conductivity type, a first diffusion region that is in contact with the semiconductor region, that includes an impurity of a second conductivity type different from the first conductivity type, and that converts incident light into charges, and a second diffusion region that includes an impurity of the second conductivity type and that directly accumulates at least a part of the charges generated in the first diffusion region. The imaging device further includes a contact plug in contact with the second diffusion region, and a capacitive element electrically connected to the second diffusion region through the contact plug.

Abstract: A solid-state imaging apparatus includes a pixel array, a column processor, and a test signal generating circuit that generates a first digital signal for testing purposes. The test signal generating circuit generates the first digital signal within one horizontal scanning period. The column processor converts a first analog signal, that is converted from the first digital signal, to a second digital signal within the one horizontal scanning period.

Abstract: An imaging device includes: a semiconductor substrate; a first photoelectric converter which is disposed in the semiconductor substrate; a second photoelectric converter different from the first photoelectric converter, which is disposed in the semiconductor substrate; a wiring layer disposed on or above the semiconductor substrate; and a capacitor which is disposed in the wiring layer and surrounds the first photoelectric converter in plan view. The capacitor includes a first electrode, a second electrode, and a dielectric layer disposed between the first electrode and the second electrode. The first electrode is connected to one of the first photoelectric converter and the second photoelectric converter.
