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