Popis: Effect of backend interconnect critical dimension variation on IMD TDDB is studied. Statistical data shows that low-k dielectric TDDB time to failure correlates well with leakage current, which reflects actual trench-to-trench or trench-to-via spacing. So a lifetime projection method, based on equal electric field, is reported. A more realistic lifetime is achieved while predicting whole lot TDDB life-time. Moreover, monitoring leakage current could be adopted into process monitoring strategy.
