Abstract

An image sensor includes: a substrate having a first surface on which light is incident and a second surface opposite to the first surface; a pixel isolation structure enclosing a pixel region in the substrate; a photoelectric conversion region in the pixel region; and a device isolation layer defining a pattern in the pixel region, wherein the device isolation layer includes a first portion contacting the pixel isolation structure and a second portion spaced apart from the pixel isolation structure, the device isolation layer extends from a second surface of the substrate into the substrate, and a length of the second portion of the device isolation layer in a vertical direction perpendicular to the first surface of the substrate is less than a length of the first portion of the device isolation layer in the vertical direction.
