Abstract: A semiconductor package includes an RFID chip positioned between a first die and a second die attached to a support substrate. The RFID chip is free of electrical connections to the dice and the support substrate. The RFID chip is sized to correspond to an interposer board. Data pertaining to operating characteristics of the dice are stored to and read from the RFID chip during back-end processing to determine abnormalities and improve yield. Said data may be stored to a database corresponding to the RFID chip in the package. A method of making a semiconductor package having an RFID chip positioned between dice is provided. The package is traceable by customers via the data stored to the RFID chip and the database.

Abstract: A method and system for tracing die at unit level, comprising: assigning a first identification to a support member including a plurality of die support units; generating a second identification corresponding to a die support unit, the second identification including the first identification and a coordinate of the die support unit within the support member; correlating the second identification to a third identification of a die; attaching the die to the die support unit to generate a packaged die; and assigning the second identification to the packaged die.
