WebTime-to-Failure (TTF) between PL vs. WL electromigration tests on two concurrently stressed structures across sixteen reticle locations is demonstrated. This WL-EM stress technique provides equivalent TTF, with no reliance on extrapolations, whilst yielding an advantage in time-to-data relative to standard PL-EM tests.
