Abstract: An image sensor includes a photoelectric converter configured to convert received light into charges in response to the received light and provide the charges to a first node, a transfer transistor configured to provide a voltage of the first node to a floating diffusion node, a reset transistor configured to reset a voltage of the floating diffusion node to a driving voltage based on a reset signal, a source follower transistor configured to provide a unit pixel output based on the voltage of the floating diffusion node, a select transistor connected to the source follower transistor and gated with a selection signal to output the unit pixel output to the outside, and a ferroelectric capacitor connected to the floating diffusion node, wherein the ferroelectric capacitor is configured to adjust a conversion gain of the floating diffusion node based on a conversion gain mode of the ferroelectric capacitor, the conversion gain mode being a first conversion gain mode, a second conversion gain mode, or a third conversion gain mode.

Abstract: An image sensor includes a first semiconductor substrate, a photoelectric conversion region in the first semiconductor substrate, and a buried insulating film on the first semiconductor substrate. The buried insulating film covers a first region of the first semiconductor substrate and exposes a second region of the first semiconductor substrate. The sensor includes a second semiconductor substrate on the buried insulating film, an operating gate structure defining a first channel of a first conductive type in the second semiconductor substrate, and a transfer gate structure defining a second channel of a second conductive type different from the first conductive type in the second region of the first semiconductor substrate.
