Current Challenges of Cu Electromigration Reliability

In today's integrated circuit (IC), more than a kilometer of metal interconnects are required to build a single microprocessor, so that many billions of metal segments exist in each IC. These metal segments are a significant reliability concern due mainly to electromigration. This concern increases with each new generation of microprocessor, which requires the use of a larger number of narrower interconnects, stressed at increasing current densities. This tutorial will address the basics of electromigration and current routes for improved reliability.
