Abstract:
A manufacturing process for an integrated circuit device, said manufacturing process redirecting one or more integrated circuit devices that have been mis-processed, each integrated circuit device having a substantially unique identification code, the method comprising:storing data and the identification code of each integrated circuit device of the integrated circuit devices, said data indicating a process flow within the manufacturing process for each integrated circuit device of the integrated circuit devices;reading the identification code of each integrated circuit device of the integrated circuit devices;accessing the data stored and the identification code of each integrated circuit device of the integrated circuit devices;evaluating the data accessed for each integrated circuit device of the integrated circuit devices;identifying any integrated circuit devices having undergone a process flow within the manufacturing process different from the process flow of their stored data; andredirecting any integrated circuit device of the integrated circuit devices identified as having been mis-processed.
