Original Abstract Submitted
An image sensor includes a substrate including a plurality of pixels and a photoelectric conversion region in an inside thereof, a pixel isolation structure isolating the plurality of pixels, and an isolation layer defining a plurality of active regions in the substrate, wherein the plurality of active regions include a center part having a plurality of branching sections extending from a center toward the plurality of pixels, the center being adjacent to each of the plurality of pixels, and an extension part in the plurality of pixels and extending in a horizontal direction from the center part. In a plan view, a first angle between a side wall of the extension part and the pixel isolation structure extending in a first direction exceeds about 45 degrees, or a second angle between two adjacent branching sections among the plurality of branching sections is less than about 90 degrees.
