Abstract
An image sensor includes a substrate having first and second surfaces. A separation structure penetrates the substrate. Photoelectric conversion device regions are spaced apart from each other in the substrate. Color filters are disposed on the second surface of the substrate. Microlenses are disposed on the color filters. The separation structure includes lower and upper separation patterns, first line portions that run parallel to each other, and second line portions that perpendicularly intersect the first line portions. An upper surface of the lower separation pattern or a lower surface of the upper separation pattern has a wavy or sawtooth shape. In intersecting regions in which the first line portions and the second line portions intersect, a vertical length of one of the lower separation pattern and the upper separation pattern is about 2 to 10 times greater than a vertical length of the other.
