  • Patent number: 8564012
    Abstract: A method for manufacturing an optoelectronic apparatus includes attaching bottom surfaces of first and second packaged optoelectronic semiconductor devices (POSDs) to a carrier substrate (e.g., a tape) so that there is a space between the first and second POSDs. An opaque molding compound is molded around portions of the first and second POSDs attached to the carrier substrate, so that peripheral surfaces of the first POSD and the second POSD are surrounded by the opaque molding compound, the space between the first and second POSDs is filled with the opaque molding compound, and the first and second POSDs are attached to one another by the opaque molding compound. The carrier substrate is thereafter removed so that electrical contacts on the bottom surfaces of the first and second POSDs are exposed. A window for each of the POSDs is formed during the molding process or thereafter.
