Abstract
A molding operation produces an extractor array by providing a mold having a plurality of cavities therein, each cavity being adapted to form an extractor suitable for coupling to an LED die; filling the mold with a plurality of glass particles; heating the glass particles above glass transition temperatures thereof so that the particles are reshaped to conform to the cavity shapes; and forming a land layer that extends between the cavities. The land layer maintains the extractors in a fixed spatial relationship with each other for subsequent handling or processing, such as a simultaneous polishing operation or in attaching the extractor array to a corresponding LED array.
