Abstract:
Packaging assemblies for optically interactive devices and methods of forming the packaging assemblies in an efficient manner that eliminates or reduces the occurrence of process contaminants. In a first embodiment, a transparent cover is attached to a wafer of semiconductor material containing a plurality of optically interactive devices. The wafer is singulated, and the optically interactive devices are mounted on an interposer and electrically connected with wire bonds. In a second embodiment, the optically interactive devices are electrically connected to the interposer with back side conductive elements. In a third embodiment, the optically interactive devices are mounted to the interposer prior to attaching a transparent cover. A layer of encapsulant material is formed over the interposer, and the interposer and encapsulant material are cut to provide individual packaging assemblies. In a fourth embodiment, the optically interactive devices are mounted in a preformed leadless chip carrier.
