Abstract :
Weak ICs that are functional under normal operating conditions are not easily screened out during CP/FT stages. In this paper, different test screening and reliability assessment techniques were applied on a batch of wafers with normal to highly resistive vias interconnects. The results and effectiveness of these techniques to screen and flag out problematic dies at wafer level testing were presented. . In additional, a fast wafer level interconnect wear-out test (via electromigration test) and a package level burn-in test were also performed to complete the evaluation.
