Abstract:
1. A solid-state imaging device, comprising: a photosensitive region having a plurality of photosensitive cells which are two-dimensionally arranged in first and second directions, each photosensitive cell including a photoelectrical conversion element for generating a signal charge corresponding to an intensity of incident light, a transfer transistor for reading the signal charge in the photoelectrical conversion element and transferring the read signal charge to a signal charge detection section, an amplifier transistor for outputting an electrical signal corresponding to changes in potential of the signal charge detection section, and a reset transistor for resetting the potential of the floating diffusion layer section to a predetermined initial value; and a line for supplying a selected voltage to the drain of the reset transistor of each photosensitive cell, wherein: a plurality of transfer control lines for controlling gates of the transfer transistors and a plurality of reset control lines for controlling gates of the reset transistors are provided so as to extend in the first direction, a plurality of output signal lines are connected to sources of the amplifier transistors in the second direction, the line supplies, as the selected voltage, a first voltage and a second voltage which is lower than the first voltage, a potential of the second voltage is higher than zero potential, and a potential of a channel, which is formed beneath a gate of the reset transistor of a given one of the photosensitive cells when a low level voltage is applied to the gate of the reset transistor of said given one of the photosensitive cells, is lower than the second voltage.
