Abstract:
1. A manufacturing process having data for integrated circuit devices manufactured during the process comprising: storing data and a substantially unique identification code for each integrated circuit device of the integrated circuit devices at either probe testing of the integrated circuit devices or thereafter, the data indicating a process flow within the manufacturing process for each integrated circuit device of the integrated circuit devices, storing data comprising: reading the substantially unique identification code of each integrated circuit device of the integrated circuit devices for evaluating the data for each integrated circuit device of the integrated circuit devices to the data for manufacturing process data stored for each integrated circuit device for identifying integrated circuit devices having a process flow within the manufacturing process different from the process flow of the data stored of the integrated circuit devices; and directing the integrated circuit devices identified as having a process flow within the manufacturing process different from the process flow of the data stored of the integrated circuit devices to another process.
