Abstract
During the formation of a metallization layer of a semiconductor device, a cap layer is formed above a metal line and subsequently an implantation process is performed so as to modify the metal in the vicinity of the interface between the cap layer and the metal line. Consequently, an improved behavior in view of electromigration of the metal line may be obtained, thereby increasing device reliability.
