  • Abstract
    Via electromigration (EM) lifetime correlates with the initial via resistance. We have found that the single Kelvin via structure is more effective as a wafer-level reliability (WLR) monitor than the via chains. Using this monitor, we have optimized the via process for 0.35 u/0.25 u applications
