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.

Abstract: An image sensor includes a substrate, and a pixel separation pattern disposed in the substrate and interposed between a plurality of unit pixels. The plurality of unit pixels include a first unit pixel region and a second unit pixel region adjacent to the first unit pixel region in a first direction. The first unit pixel region and the second unit pixel region respectively include a first transfer gate and a second transfer gate. The pixel separation pattern includes a first pixel separation part interposed between the first unit pixel region and the second unit pixel region, and a second pixel separation part spaced apart from the first pixel separation part in the first direction. A top surface of the first pixel separation part is lower than a top surface of the second pixel separation part.

Abstract: An image sensor includes a substrate, a photoelectric conversion region in the substrate with the substrate defining a substrate trench on the photoelectric conversion region, a floating diffusion region adjacent to a side surface of the substrate trench, in the substrate, a gate dielectric film that extends along the side surface and a lower surface of the substrate trench and a transfer gate electrode which includes a lower gate that fills a portion of the substrate trench on the gate dielectric film and has a first width, and an upper gate that has a second width smaller than the first width on the lower gate. The gate dielectric film includes a lower dielectric film interposed between the substrate and the lower gate and has a first thickness, and an upper dielectric film adjacent to the floating diffusion region and has a second thickness greater than the first thickness.
