Abstract
An image sensor includes a device isolation layer disposed in a substrate and defining pixel regions, and a grid pattern on a surface of the substrate. The grid pattern overlaps the device isolation layer between adjacent pixel regions in a direction perpendicular to the surface. The grid pattern has a width less than a width of the device isolation layer.
