Abstract:
An integrated circuit manufacturing process for separating integrated circuit devices for enhanced reliability testing from a group of integrated circuit devices undergoing back-end test procedures, the integrated circuit devices each having a substantially unique identification code, the method comprising: storing a flag in connection with the identification code of each integrated circuit device of theintegrated circuit devices in the group to indicate whether each integrated circuit device is in need of enhanced reliability testing; reading the identification code of each integrated circuit device of the integrated circuit devices in the group; accessing the enhanced reliability testing flag stored in connection with each of the read identification codes; sorting the integrated circuit devices in the group in accordance with whether their enhanced reliability testing flag indicates they are in need of enhanced reliability testing; and performing enhanced reliability testing on integrated circuit devices in the group in need of enhanced reliability testing.
