Abstract
Image sensors may include a semiconductor substrate including a first surface and a second surface opposite the first surface and including a plurality of pixels, a first pixel isolation structure including a first trench recessed from the first surface of the semiconductor substrate into the semiconductor substrate and a conductive layer in the first trench, and a second pixel isolation structure including a second trench and a third trench each recessed from the second surface of the semiconductor substrate into the semiconductor substrate and a dielectric layer in the second trench and the third trench. The first pixel isolation structure and the second pixel isolation structure may contact each other and separate the pixels from each other in the semiconductor substrate.
