Abstract
An image sensor includes a substrate having a plurality of pixel sections. The substrate has first and second surfaces that are opposite to each other. A photoelectric conversion region is in each of the pixel sections. A first isolation pattern is disposed in the substrate and is positioned between the pixel sections. A gate electrode is on the photoelectric conversion region. A lower portion of the gate electrode is inserted into the substrate. An upper portion of the gate electrode protrudes beyond the first surface of the substrate. A floating diffusion region is on the photoelectric conversion region. The floating diffusion region is positioned on one side of the gate electrode. The floating diffusion region includes a doping pad and a first impurity region. The first impurity region surrounds a lower portion of the doping pad. The doping pad is horizontally spaced apart from the first isolation pattern.
