Electromigration was a major road block in the pursuit of further miniaturized electronics. In the next generation micro and sub-micro electronics current density was expected to exceed 107A/cm2. An electromigration induced strain-current density model was proposed here and was implemented into a finite-element procedure for the solution of boundary/initial value electromigration problems. Numerical simulations were compared with experimental data. The comparisons validated the model.
