Abstract: Product management and/or prompt defect analysis of a semiconductor device may be carried out without reducing the throughput in assembly and testing. Unique identification information is attached to a plurality of substrates (lead frames) used in manufacturing a semiconductor device (QFP) and to a transport unit for transporting a plurality of substrates, respectively. Identification information (rack ID) of the transport unit and identification information (substrate ID) of the substrate stored into the transport unit are associated with each other. The substrate is taken out from the transport unit set to a loader unit of each manufacturing apparatus and supplied to a processing unit, of the apparatus and in storing the substrate, the processing of which is complete, into a transport unit of an unloader unit of the apparatus, an association between identification information of the transport unit and the identification information of the substrate is checked.

Abstract: Reading reliability of a code formed in a semiconductor device is improved. A manufacturing method of semiconductor devices according to one embodiment includes a step of forming a sealing body MR in a plurality of device regions DVP with a code (first identification information) MK3 being formed outside the device regions DVP of a wiring substrate. Also, the manufacturing method of semiconductor devices according to one embodiment includes a step of, after forming the sealing body MR, reading the code MK3 and affixing another code (second identification information) to the sealing body MR. Further, before the step of forming the sealing body MR, a dam part DM is formed between a marking region MKR in which the code MK3 is formed and the device regions DVP.
