Abstract:

Back-end-of-line (BEOL) reliability, comprising barrier, dielectric and current-carrying metal reliability, is a major challenge for future IC generations as the reliability margin of the dielectric/barrier/copper systems is shrinking. In this contribution, the impact of interconnect scaling on BEOL reliability is outlined and illustrated by low-k TDDB, electromigration and stress-induced-voiding results. © 2005 IEEE.
