    摘要: A process for simultaneously forming a first opening to a copper contact structure, and a deeper, second opening, overlying a fuse structure, has been developed. The process features the use of a barrier metal shape, located on a recessed copper contact structure, providing the needed etch stop during a dry etching procedure used to define a first opening in a composite insulator layer. The low etch rate exhibited by the barrier metal shape, in this dry etching environment provides protection of the recessed copper contact structure during the extended dry etching procedure, which is employed to form a deeper, second opening, in thicker dielectric layers, in a region overlying the fuse structure.
