ABSTRACT:
Individual two-dimensional barcodes30, 91and173are provided for individual chips31arrayed on a wafer50, individual lead frames93to each of which chips92are bonded and individual packaged products171constituted of resin sealed semiconductor chips based upon chip ID information to enable information management to be implemented separately for individual chips31, individual frames93and individual chip products171. Thus, a higher degree of efficiency and a higher degree of accuracy in the information management for semiconductor devices are achieved in all processes of semiconductor production including the individual manufacturing processes, the physical distribution process, the shipping process and the claim handling process.
