An image sensor includes at least one photosensitive element disposed in a semiconductor substrate. Metal conductors may be disposed on the semiconductor substrate. A filter may be disposed between at least two individual metal conductors and a micro-lens may be disposed on the filter. There may be insulator material disposed between the metal conductors and the semiconductor substrate and/or between individual metal conductors. The insulator material may be removed so that the filter may be disposed on the semiconductor substrate.

Self-aligned filter for an image sensor

An image sensor having a plurality of micro-lenses disposed on a semiconductor substrate. A first micro-lens has a different focal length, height, shape, curvature, thickness, etc., than a second micro-lens. The image sensor may be back side illuminated or front side illuminated.
