Abstract:
Color image sensors include pixels having varying color characteristics. One of the pixels is a cyan-type pixel, which includes primary and secondary photodetectors therein. The primary photodetector extends adjacent a portion of a surface of a semiconductor substrate that is configured to receive visible light incident thereon. The secondary photodetector is buried in the semiconductor substrate. The secondary photodetector is configured to receive visible light that has passed through the primary photodetector.
