We present a rigorous analytical solution for motion of an elliptical void under gradient stress field. An elliptical void will move to the region of high stress at a velocity inversely proportional to an equivalent void size, strongly affected by the shape parameter of the void, average stress, stress gradient, and stress states.

    We use a simple closed-form lifetime model for stress-induced voiding (SIV) or stress migration for Al- or Cu-based interconnects. Stress-induced voiding is treated as a process of void nucleation/growth and stress relaxation through atomic diffusion driven by a stress gradient. We developed a...

    Electromigration experiments were conducted to investigate the thresholds required for electromigration-induced extrusion failures in Cu/low-k interconnect structures. Extrusions at the anode were observed after long periods of void growth. Characterization of failure sites was carried out using...
