Abstract
An image sensor includes a substrate including opposite first and second surfaces, first and second gates, on the first surface of the substrate, which each extend in a first direction, a first isolation layer in the substrate between the first and second gates and having a first width in a second direction crossing the first direction, a second isolation layer on the first isolation layer, in the substrate, and having a second width smaller than the first width in the second direction. The second isolation layer is closer to the second surface of the substrate than the first isolation layer. A vertical distance between the first isolation layer and the second isolation layer is ⅓ or less of a height of the first isolation layer.
