Abstract
An image sensor has a large bridge margin from a repulsive force between adjacent micro lenses having different surface properties. The image sensor has a larger bridge margin with a configuration of a stepped portion between two areas, where the first and the second group of micro lenses are formed, over a planarization layer below these two areas. Thus, a zero gap is realized, where no gap between micro lenses exists, and the fill factor of micro lens is maximized. By the realization of the zero gap, interference effects decrease, noise decreases, and fill factor increases, and thus the sensitivity of an image sensor increases, especially the green sensitivity.
