A device, system and method for evaluating reliability of a semiconductor
chip are disclosed. Strain is determined at a location of interest in a
structure. Failures are evaluated in a plurality of the structures after
stress cycling to determine a strain threshold with respect to a feature
characteristic. Structures on a chip or chips are evaluated based on the
feature characteristic to predict reliability based on the strain
threshold and the feature characteristic. Predictions and design changes
may be made based on the results.
