We show that a simple post-stress test can provide a good early reliability indicator. The defect types that have been revealed by this post-stress test are two types of conductive particles on metal levels. This early indicator has been of great value when dealing with potentially contaminated wafers/lots and to evaluate and to prioritize the corrective actions to solve the line issues
