Abstract
An interconnect structure and method for an integrated circuit chip for resisting electromigration is described incorporating patterned interconnect layers of Al or Al--Cu and interlayer contact regions or studs of Al.sub.2 Cu between patterned interconnect layers. The invention overcomes the problem of electromigration at high current density in the interconnect structure by providing a continuous path for Cu and/or Al atoms to move in the interconnect structure.
