Patent ID: 8294880

Claim:
An image sensor comprising: a photoelectric conversion region for generating photo-charges by receiving light, on a semiconductor substrate doped with a first impurity; a first charge storage region spaced apart from the photoelectric conversion region to one side of the photoelectric conversion region on the substrate, and a second charge storage region spaced apart from the photoelectric conversion region to another side of the photoelectric conversion region, wherein the first and second charge storage regions are each doped with a second impurity; a first reset diffusion region spaced apart from the first charge storage region away from the photoelectric conversion region on the substrate, and a second reset diffusion region spaced apart from the second storage region away from the photoelectric conversion region on the substrate, wherein the first and second reset diffusion regions are each doped with the second impurity; a first transfer gate formed between the photoelectric conversion region and the first charge storage region, and a second transfer gate formed between the photoelectric conversion region and the second charge storage region, above the substrate; and a first reset gate formed between the first charge storage region and the first reset diffusion region, and a second reset gate formed between the second charge storage region and the second reset diffusion region, above the substrate; wherein a predetermined voltage is applied to the first and second transfer gates such that the photo-charges of the photoelectric conversion region are selectively transferred to the first and second charge storage regions, and a predetermined voltage is applied to the first and second reset gates such that electric potential of the first and second charge storage regions are reset to input power source voltage.
