Abstract:
An image sensor includes a substrate including opposite first and second surfaces, first and second gates, on the first surface of the substrate, which each extend in a first direction, a first isolation layer in the substrate between the first and second gates and having a first width in a second direction crossing the first direction, a second isolation layer on the first isolation layer, in the substrate, and having a second width smaller than the first width in the second direction. The second isolation layer is closer to the second surface of the substrate than the first isolation layer. A vertical distance between the first isolation layer and the second isolation layer is ⅓ or less of a height of the first isolation layer.

Claim (Index 17):
An image sensor comprising:\n a substrate comprising a first surface and a second surface disposed opposite to each other; a photoelectric conversion element in the substrate; first and second gates spaced apart from one another on the first surface of the substrate; a first isolation layer in the substrate between the first and second gates; a second isolation layer in the substrate, wherein the second isolation layer comprises polysilicon, and wherein the second isolation layer vertically overlaps the first isolation layer and is closer to the second surface of the substrate than the first isolation layer; and a micro lens on the second surface of the substrate, wherein a vertical distance between the first isolation layer and the second isolation layer is \u2153 or less of a height of the first isolation layer.
