Abstract :
An alternative method of analyzing time-dependent dielectric breakdown (TDDB) data for low-k dielectrics is presented. The analysis shows that time to breakdown is well correlated to the Poole-Frenkel emission equation, and therefore the radicE-model is a more accurate model in describing the TDDB physics for low-k BEOL dielectrics.
