Zusammenfassung:An image sensor may include a first photo gate and a second photo gate each extending substantially in parallel in a first direction, the first photo gate and the second photo gate isolated from direct contact with each other in a second direction, the second direction substantially orthogonal to the first direction, a first overflow gate between the first photo gate and the second photo gate, the first overflow gate extending in the first direction, a first charge collection region on the first photo gate, a second charge collection region on the second photo gate and isolated from direct contact with the first charge collection region in the second direction, a first floating diffusion region that may receive first charge from the first charge collection region and output the first charge, and a second floating diffusion region that may receive second charge from the second charge collection region and output the second charge.
