An image sensor device may include a dual-gated charge storage region within a substrate. The dual-gated charge storage region includes first and second diodes within a common charge generating region. This charge generating region is configured to receive light incident on a surface of the image sensor device. The first and second diodes include respective first conductivity type regions responsive to first and second gate signals, respectively. These first and second gate signals are active during non-overlapping time intervals.

An image sensor includes a photoelectric converter, a reflector, and a charge carrier guiding region. The reflector is disposed under the photoelectric converter, and the charge carrier guiding region is disposed between the photoelectric converter and the reflector. The reflector reflects incident light passed by the photoelectric converter back through the photoelectric converter for increasing photoelectric conversion efficiency and reduced crosstalk. The charge carrier guiding region dissipates undesired charge carriers for further increasing photoelectric conversion efficiency.
