Abstract: An image sensor is provided. The image sensor includes a substrate including a first side on which light is incident and a second side opposite the first side; a first separation pattern extending from the second side, the first separation pattern being interposed between unit pixels in the substrate of a light-receiving region and a light-shielding region provided around the light-receiving region; a second separation pattern extending from the first side and overlapping the first separation pattern, the second separation pattern being provided in the substrate of the light-receiving region; and a contact film electrically connected to the first separation pattern, the contact film being provided in the substrate of the light-shielding region. A contact trench which extends from the first side is formed in the light-shielding region of the substrate and exposes the first separation pattern, and the contact film fills at least a part of the contact trench.
