ABSTRACT:
An integrated circuit (IC) wafer includes a plurality of die and a first die indicator (FDI) formed on the wafer in a metal layer. The plurality of die include a first potentially good die and the FDI, which is detectable by a machine vision recognition system, provides a unique indication of the first potentially good die.
