An image sensor including: a first photodiode; a first circuit including an overflow transistor and a first transfer transistor connected to the first photodiode, a switch element connected to the first transfer transistor and a capacitor disposed between the first transfer transistor and the switch element, wherein the capacitor is a physical capacitor; a second photodiode; and a second circuit including a second transfer transistor connected to the second photodiode, a reset transistor connected to an output of the first circuit and a driving transistor connected to the second transfer transistor and the output of the first circuit.

Image sensor

Image sensors include a second photoelectric conversion device disposed in a lower portion of a substrate and a first photoelectric conversion device extending between the secondary photoelectric conversion device and a light receiving surface of the substrate. Electrical isolation between the first and second photoelectric conversion devices is provided by a photoelectron barrier, which may be an optically transparent electrically insulating material. MOS transistors may be utilized to transfer photoelectrons generated within the first and second photoelectric conversion devices to a floating diffusion region within the image sensor. These transistors may represent one example of means for transferring photoelectrons generated in the first and second photoelectric conversion devices to a floating diffusion region in the substrate, in response to first and second gating signals, respectively. The first and second gating signals may be active during non-overlapping time intervals.
