发明名称 Method for manufacturing identification codes of integrated circuits
摘要 The present invention reveals a method for manufacturing identification codes of integrated circuit. A number of the test machine, a serial number and a period of time ahead of loading a test pattern are written into an integrated circuit in the process of testing as the identification code. Thus, the identification codes of each integrated circuit of normal lot, re-testing lot and quality control lot is distinct to avoid the problems caused by repetitive identification codes.
