An image sensor having pixels that include two patterned semiconductor layers. The top patterned semiconductor layer contains the photoelectric elements of pixels having substantially 100% fill-factor. The bottom patterned semiconductor layer contains transistors for detecting, resetting, amplifying and transmitting signals charges received from the photoelectric elements. The top and bottom patterned semiconductor layers may be separated from each other by an interlayer insulating layer that may include metal interconnections for conducting signals between devices formed in the patterned semiconductor layers and from external devices.

Pixel having two semiconductor layers, image sensor including the pixel, and image processing system including the image sensor

An image sensor includes a plurality of photoelectric detectors, a plurality of color filters, and at least one pixel isolation region between adjacent ones of the photoelectric detectors. The color filters include a white color filter, and the color filters correspond to respective ones of the photoelectric detectors. The at least one pixel isolation region serves to physically and at least partially optically separate the photoelectric detectors from one another.
