Abstract: Disclosed is an image sensor comprising a substrate including a pixel area and an optically black area and having a first surface and a second surface that are opposite to each other, a plurality of color filters on the second surface of the substrate on the pixel area, and a first optically black pattern in a first recess on the second surface of the substrate on the optically black area. The first optically black pattern includes a material that is the same as a material of one of the color filters. Top surfaces of the color filters and a top surface of the first optically black pattern are at the same level.

Abstract: An image sensor includes: a substrate including an active region and a peripheral region, unit pixels disposed on the active region, device isolation patterns defining the unit pixels disposed on the active region, a light-shield layer on the substrate and having a grid structure defining optical transmission regions, color filters on the light-shield layer, and microlenses on the color filters. The device isolation patterns include first device isolation patterns and a second device isolation pattern, wherein the first device isolation patterns are disposed on a central portion of the active region, and the second device isolation pattern is between the first device isolation patterns and the peripheral region. The first device isolation patterns have a first top surface substantially parallel to a bottom surface of the substrate. The second device isolation pattern has a second top surface, wherein the second top surface approaches the bottom surface of the substrate in a direction toward the peripheral region.
