Abstract
An image sensor includes a substrate including a plurality of pixel regions, a first surface, and a second surface that is opposite to the first surface, and a deep device isolation pattern penetrating the substrate and between the plurality of pixel regions, the deep device isolation pattern including a first filling pattern adjacent to the second surface, a second filling pattern on the first filling pattern and adjacent to the first surface, a semiconductor pattern between the first filling pattern and the substrate, an oxidized semiconductor pattern on the semiconductor pattern and between the substrate and the second filling pattern, and a side insulating pattern between the semiconductor pattern and the substrate, where the semiconductor pattern directly contacts the oxidized semiconductor pattern.
