Abstract
An image sensor including a substrate including a first and second surface; a pixel isolation structure penetrating the substrate, arranged in a pixel isolation trench extending from the first to second surface of the substrate, and defining a pixel region; a plurality of sub pixel regions on the pixel region; a plurality of photoelectric conversion regions on the plurality of sub pixel regions; a signal separation structure between the plurality of sub pixel regions, the signal separation structure being in a signal separation trench extending from the second surface of the substrate toward the first surface of the substrate into the substrate; and a micro lens on the second surface of the substrate, the micro lens corresponding to the pixel region, wherein the signal separation structure includes an insulating layer, and the pixel isolation structure includes a conductive layer; and a liner layer between the conductive layer and the substrate.
