How about using photoresist to 'glue' your chips onto a bigger chip/wafer? Here at Glasgow Uni several people have used such an approach with success (many work with samples as small as 4 mm by 4 mm). S1818 is the resist of choice but I can't see why other photoresists would not work. If you want further details on the procedure let me know.
