Abstract

SEMATECH has sponsored a "Test Method Evaluation"study to understand the trade-offs among the most commontest methodologies used in the industry[1,2]. This paper presentsthe results of the failure analysis portion of thatproject. The testing, reliability stressing, characterization,fault diagnosis and physical analysis results are presentedfor 25 devices including "IDDq-only" failures and "delaytest-only" failures.
