  • Publication number: 20130221380
    Abstract: A method for manufacturing a plurality of optoelectronic apparatuses include attaching bottom surfaces of a plurality of packaged optoelectronic semiconductor devices (POSDs) to a carrier substrate (e.g., a tape) so that there is a space between each POSD and its one or more neighboring POSD(s). A light reflective molding compound is molded around a portion each of the POSDs attached to the carrier substrate so that a reflector cup is formed from the light reflective molding compound for each of the POSDs. The light reflective molding compound can also attach the POSDs to one another. Alternatively, an opaque molding compound can be molded around each POSD/reflector cup to attach the POSDs/reflector cups to one another and form a light barrier between each POSD and its neighboring POSD(s). The carrier substrate is thereafter removed so that electrical contacts on the bottom surfaces of the POSDs are exposed.

  • Publication number: 20130207126
    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.
