1. A method of the post-production reliability of a repairable integrated circuit die component, said method comprising:
- performing an initial post-production test on the component to identify repairable defects in the component; and
classifying the component into a classification of a plurality of reliability probability classifications based on the number of repairable defects identified by the initial test; and
estimating the reliability of the component based on the classification.

Abstract
A system and method for determining the early life reliability of an electronic component, including classifying the electronic component based on an initial determination of a number of fatal defects, and estimating a probability of latent defects present in the electronic component based on that classification with the aim of optimizing test costs and product quality.

13. A method for predicting the post-production reliability of an integrated circuit die component, said method comprising:
-
performing an initial post-production test to identify a number of killer defects; classifying a component into one of a plurality of reliability probability classifications based on the number of killer defects identified by the initial test; and optimizing further testing of the component to identify the presence of latent defects, based on the classification thereof. - View Dependent Claims (14, 15, 16, 19, 20)
