Distance measuring sensor including double transfer gate and three dimensional color image sensor including the distance measuring sensor
Provided are a distance measuring sensor including a double transfer gate, and a three dimensional color image sensor including the distance measuring sensor. The distance measuring sensor may include first and second charge storage regions which are spaced apart from each other on a substrate doped with a first impurity, the first and second charge storage regions being doped with a second impurity; a photoelectric conversion region between the first and second charge storage regions on the substrate, being doped with the second impurity, and generating photo-charges by receiving light; and first and second transfer gates which are formed between the photoelectric conversion region and the first and second charge storage regions above the substrate to selectively transfer the photo-charges in the photoelectric conversion region to the first and second charge storage regions.
