Claim Text:
1. A method for fabricating a plurality of optoelectronic devices, comprising: (a) performing through silicon via (TSV) processing on a wafer, which includes a plurality of light detector sensor regions, to thereby form a plurality of vias; (b) tenting and plating the vias and performing wafer back metallization, after performing the TSV processing; (c) attaching each of a plurality of light source dies to a top surface of the wafer; and (d) molding a light transmissive material to encapsulate the light detector sensor regions and the light sensor dies in the light transmissive material, after the (b) tenting and plating the vias and performing wafer back metallization, and after the (c) attaching the plurality of light source dies to the top surface of the wafer; (e) fabricating opaque barriers including opaque optical crosstalk barriers; (f) attaching solder balls or other electrical connectors to the bottom of the wafer; and (g) dicing the wafer to separate the wafer into a plurality of optoelectronic devices.
