Abstract

A method comprises depositing an optical filter layer on a glass wafer, then cutting the wafer into dice. The dice are positioned on a carrier and encapsulated in a molding compound to form a reconstituted wafer, and the wafer is back-ground and polished. Lens faces are positioned on opposing surfaces of the glass dice and spacers are positioned on one side of the wafer. The wafer is then cut into lens modules, each having two side-by-side lenses with an opaque molding compound barrier between. The individual modules are attached to devices that require dual lenses, such as, e.g., proximity sensors that use a light source and a light receiver or detector.
