Method and article of manufacture for micro-lens resulting from multi-stage fabrication technique

摘要

Micro-lenses are formed on the surface of a semiconductive circuit through a plurality of processing stages. In each stage, an alternate lens placement pattern is imparted onto micro-lens suitable material. Unwanted material is removed and micro-lenses are formed from the remaining material. Subsequent stages are applied until all desired micro-lenses in a structure are defined and formed from alternate placement patterns.
