Description

Three-dimensional finite element simulations were used to model stress relaxation due to diffusion along interfaces in a damascene copper interconnect structure. By fitting the predicted stress relaxation rates to the available experimental results, we have identified the interfaces that contribute to stress relaxation in the structure, and have estimated values for their diffusion coefficients
