Abstract:
1. An integrated circuit manufacturing process using data related to manufacturing procedures used previously that a plurality of integrated circuits of Dynamic Random Access Memory (DRAM) semiconductor devices have undergone for selecting manufacturing procedures the plurality of integrated circuits of the Dynamic Random Access Memory (DRAM) semiconductor devices are to undergo, each Dynamic Random Access Memory (DRAM) semiconductor device having integrated circuits and having a substantially unique identification code, the manufacturing process comprising: storing data in association with the substantially unique identification code of each Dynamic Random Access Memory (DRAM) semiconductor device of the plurality identifying manufacturing procedures each Dynamic Random Access Memory (DRAM) semiconductor device has undergone, the storing data comprising storing data that identifies spare rows and columns used in repairing each DRAM semiconductor device; automatically reading the substantially unique identification code of each Dynamic Random Access Memory (DRAM) semiconductor device; accessing the data stored in association with the substantially unique identification code of each Dynamic Random Access Memory (DRAM) semiconductor device; and analyzing the data stored in association with the substantially unique identification code of each Dynamic Random Access Memory (DRAM) semiconductor device for determining the manufacturing procedures used previously for each Dynamic Random Access Memory (DRAM) semiconductor device.
