Abstract

In sub-micron processes, resistive path defectsare increasingly contributing to the yield loss and thecustomer fail pareto. Data has been collected on a seriesof ASIC products and compares the effectiveness of fullvector set transition delay fault tests with reduced vectorsets, minVDD, customer functional tests and customerssystem fails. Results show that fault models do not predictthe defect coverage well and cost effective screening offrequency outliers and minVDD outliers is possible and iscritical in improving customer quality.
