摘要
Electromigration has been a key and persistent reliability problem in microelectronic technology. It involves both atomic flux and electron flux whose distribution in interconnects is most important concerning electromigration damage. Comparing with Al and Cu interconnects, eutectic solders are two-phase alloys with higher atomic diffusivity. In this article, the unique features of solder joints electromigration will be discussed with emphasis on the effects of current crowding, eutectic composition, polarity effect on chemical reaction and solder composition.
