Abstract
An image sensor includes a substrate having a first surface and a second surface facing each other, a plurality of photoelectric conversion regions disposed in the substrate, an isolation pattern disposed in the substrate between the photoelectric conversion regions, a conductive connection pattern disposed on the isolation pattern and in a trench penetrating the first surface of the substrate, and a first impurity region disposed in the substrate and adjacent to the first surface of the substrate. A first sidewall of the conductive connection pattern is in contact with the first impurity region. A dopant included in the conductive connection pattern includes the same element as an impurity doped in the first impurity region.
