Abstract
A chip scale packaging for optical image sensor integrated circuits is disclosed. Micro lenses are placed on top of a wafer having the image sensors formed thereon. An adhesive matrix is placed atop of the wafer. The adhesive matrix has openings that align with the micro lensed sensor array on top of the wafer. A cover glass is then placed over the adhesive and the adhesive is activated to secure the cover glass to the wafer. Because the adhesive has openings above the micro lensed portion no distortion or reduction of the lens effect is caused by the adhesive.
