Abstract
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.
