Abstract
The inventive concept provides image sensors and methods of forming the same. In the image sensor, a surface trap region may be disposed to be adjacent to a surface of a substrate lens component. Thus, a dark current characteristic may be improved.
Claims8
An image sensor comprising:
- a substrate including a first surface, a second surface on which light is incident, and a plurality of pixels, the first and second surfaces being opposite to each other;
- a photoelectric conversion component formed on the substrate of each of the respective pixels;
- a multi-layered interconnection and a multi-layered interlayer insulating layer on the first surface;
- a substrate lens component protruding from the second surface;
- and
- a surface trap region adjacent to a surface of the substrate lens component.
