Abstract:
A test method in an integrated circuit (IC) manufacturing process for determining IC devices in need of enhanced reliability testing from a group of IC devices undergoing test procedures, the IC devices each having a substantially unique identification (ID) code, the method comprising:storing an enhanced reliability testing flag in connection with the ID code of each IC device of the IC devices in the group indicating whether each IC device is in need of said enhanced reliability testing; automatically reading the ID code of each IC device of the IC devices in the group; accessing the enhanced reliability testing flag stored in connection with each of the automatically read ID codes of each IC device of said IC devices in said group having the ID code thereof read; sorting the IC devices in accordance with whether their said enhanced reliability testing flag indicates the IC devices are in need of said enhanced reliability testing; and performing testing of IC devices in need of said enhanced reliability testing.
