1. A manufacturing process for separating a plurality of integrated circuit semiconductor devices for enhanced reliability testing from a group of integrated circuit semiconductor devices, the integrated circuit semiconductor devices each having a substantially unique identification code for indicating a testing status of each integrated circuit semiconductor device based upon any previous test of each integrated circuit semiconductor device, the process comprising:

  • storing an indicator in connection with the identification code of each of the integrated circuit semiconductor devices in the group indicating if each integrated circuit semiconductor device requires enhanced reliability testing;

    reading the identification code of each of the integrated circuit semiconductor devices in the group;

    accessing the enhanced reliability testing indicator stored in connection with each of the identification codes for each of the integrated circuit semiconductor devices in the group;

    sorting the integrated circuit semiconductor devices in the group from their enhanced reliability testing indicator; and

    performing the enhanced reliability testing on the integrated circuit semiconductor devices needing the enhanced reliability testing.
