ABSTRACT:
Micro-lenses for use in imagers and their method of manufacture from intermediate lens structures are described. Lithographic masks are used to remove unwanted portions from the intermediate lens structures and to remove cut-out portions from the intermediate lens structures to alter the radius of the resultant micro-lenses. Lithographic masks are also used to inhibit pull-back of the micro-lenses during a reflow step.
