Abstract
An image sensor is provided comprising a substrate comprising first and second surfaces opposite to each other. A first isolation layer is disposed on the substrate and forms a boundary of a sensing region. A second isolation layer is disposed at least partially in the substrate within the sensing region and has a closed line shape. A photoelectric conversion device is disposed within the closed line shape of the second isolation layer, and a color filter is disposed on the first surface of the substrate.
