Abstract
This paper reviews di€erent known physical phenomena acting during electromigration, such as changes in the mechanical stress of the metal line, void growth and precipitation/dissolution of alloy elements (Cu, Si) and their e€ects on early resistance changes. The superposition of all these phenomena is also discussed to describe the typical early resistance changes detected in Al±Cu lines of the present technology
