Claim:
1. A wafer-level method of fabricating optoelectronic modules, the method comprising: providing a support substrate on which are mounted a plurality of optoelectronic devices; performing a first vacuum injection technique, using a first vacuum injection tool, to surround each optoelectronic device laterally with a transparent overmold region, wherein the overmold region also covers a top surface of each optoelectronic device; performing a replication technique to form a respective passive optical element on a top surface of each transparent overmold region; and performing a second vacuum injected technique to form sidewalls laterally surrounding and in contact with sides of each transparent overmold region, wherein both the replication technique and the second vacuum injection technique are performed using a combined replication and vacuum injection tool, and wherein the replication technique includes placing a replication material onto the combined replication and vacuum injection tool and pressing each transparent overmold region into contact with the replication material so that the replication material is pressed between each transparent overmold region and corresponding replication sections of the combined replication and vacuum injection tool.
