Short stripe effect and electromigration stress
From the perspective of the recent contributions to the field, we discuss essential physics behind the short-stripe effect in drift velocity electromigration (EM), transition to the creep controlled electromigration in short, near-threshold interconnects, the role of dynamic EM stresses and possible mechanism of their relaxation by non-constrained diffusional creep into hillocks.
