The advantages of using copper for interconnection in microcircuits are mostly due to its lower resistance (bulk resistivity) compared to aluminum metallization. Copper-based metallization has specific resistance of less than 2 μΩ-cm compared to more than 3 μΩcm for aluminum metallization. In combination with a reduced susceptibility to electromigration… (More)
