      If correlation wafers are tested repeatedly to ensure proper test set-ups, the probe results can be used to calculate yield limits due to tester non-repeatibilty or “twinkling dice”. The formula is: Where: The number of twinkling dice that fails i times. The number of times these dice failed. The gross number of dice in the (correlation) wafer
