ABSTRACT:
A semiconductor device including a semiconductor substrate having a photosensor formed therein; a first layer overlying the substrate, the first layer includes a portion having a generally concave shaped surface being the negative shaped of a micro-lens to be formed there over; a second layer overlying the first layer, the second layer including a generally convex shaped portion vertically aligned with and mating with the generally concave shaped surface, the generally convex shaped portion being constructed and arranged to define a micro-lens positioned to cause parallel light passing through the micro-lens to converge on and strike the photosensor.
