Abstract
According to one exemplary embodiment, a method for determining a Weibull slope at a specified temperature utilizing a test structure comprises a step of performing a number of groups of failure tests on the test structure to determine a number of groups of test data, where each of the groups of failure tests is performed at a respective one of a number of test temperatures, and where each group of failure tests corresponds to a respective group of test data. The method further comprises utilizing the number of groups of test data to determine a scaling line. The method further comprises determining a scaling factor at the specified temperature utilizing the scaling line. The method further comprises utilizing the scaling factor to determine the Weibull slope. The method may further comprise utilizing the Weibull slope to determine a lifetime of the semiconductor die.
