A sequence of electrical tests was developed to provide a viable alternative to the performance of high magnification visual inspection for high reliability integrated circuits in a large volume production environment. The primary approach was based on: close monitoring of the Substrate-N epi I-V characteristics, voltage overstress exposure and subsequent verification of the devices' low level leakage and thermal response. This method was implemented and evaluated for the specific case of a 16K Bipolar Schottky PROM. Reliability tests indicated that devices processed using the proposed alternate screen sequence achieved failure rates as low as those obtained using high magnification visual inspection.
