  • Abstract
    A low level IC burn-in failure mechanism caused by post-passivation sodium contamination has been observed. An accelerated stress test has been developed based on SIMS, SEM and TEM analysis. The results have been compared to burn-in data. Four types of passivation films and two types of assembly processes were used to demonstrate the effectiveness of this test.
