Abstract:
A manufacturing process for integrated circuit devices comprising:storing data and a substantially unique identification code of each integrated circuit device of said integrated circuit devices, said data indicating a process flow within said manufacturing process for each integrated circuit device of said integrated circuit devices, said storing data comprising: storing said substantially unique identification code of said each integrated circuit device of said integrated circuit devices and a die location on an electronically stored wafer map for each integrated circuit device; reading said substantially unique identification code of each integrated circuit device of said integrated circuit devices; evaluating said data for each integrated circuit device of said integrated circuit devices to said data stored for each integrated circuit device; identifying integrated circuit devices having a process flow within said manufacturing process different from said process flow of said stored data of said integrated circuit devices; and directing said each integrated circuit device of said integrated circuit devices identified as having a process flow within said manufacturing process different from said process flow of said stored data of said integrated circuit devices to another process.
