Abstract: An image sensor includes a substrate including a first surface and a second surface facing the first surface, a first photodiode located in a first region of the substrate and generating photocharges from light incident on the first region, a second photodiode located in a second region of the substrate and generating photocharges from light incident on the second region, and an isolation structure defining the first region in which the first photodiode is located and the second region in which the second photodiode is located, and extending between the first photodiode and the second photodiode. An area of the second region is smaller than an area of the first region, a first end of the isolation structure is coplanar with the second surface, and the isolation structure extends in a vertical direction from the second surface of the substrate toward the first surface of the substrate.

Abstract: An image sensor includes a substrate including a pixel region and a peripheral circuit region, and a first device isolation layer disposed in the substrate to define a plurality of unit pixels that are adjacent to each other in a first direction in the pixel region. Each of the plurality of unit pixels includes at least one light sensing element disposed in the substrate. The image sensor includes an interlayer insulating structure on the substrate, and a first blocking structure disposed on the first device isolation layer and penetrating the interlayer insulating structure. The first blocking structure is disposed between the plurality of unit pixels when viewed from a plan view. The first blocking structure extends in a second direction intersecting the first direction when viewed from a plan view.
