ABSTRACT:
Individual two-dimensional barcodes are provided for individual chips arrayed on a wafer, individual lead frames to each of which chips are bonded and individual packaged products constituted of resin sealed semiconductor chips based upon chip ID information, to enable information management to be implemented separately for individual chips, individual frames and individual chip products. 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.
