Abstract
An image sensor includes: a gate structure on a semiconductor layer of a first conductive type; a first impurity region of the first conductive type aligned with one side of the gate structure and extending to a predetermined depth from a surface portion of the semiconductor layer; spacers formed on sidewalls of the gate structure; and a second impurity region of a second conductive type formed in a portion of the semiconductor layer under the first impurity region, wherein the first impurity region includes: a first region of which portion aligned with the one side of the gate structure; a second region aligned with the one of the spacers and having a concentration higher than that of the first region; and a third region apart from the one side of the gate structure with a predetermined distance and having a concentration higher than that of the second region.
