The local dielectric cap represents an intentionally created weak point in the metal wiring line of a dual-damascene interconnect, which induces electromigration (EM) voiding in the line, rather than at the bottom of a via extending downwardly from the metal wiring line. Since the critical void size in line fails, especially with metal cap layer (liner) redundancy, is much larger than that in via fails, the EM lifetime can be significantly increased.
