Abstract

Traditional metrology has been unable to adequately address the reliability needs of emerging integrated circuits at the nano scale; thus, new metrology and techniques are needed. In this paper, we use microwave propagation characteristics (insertion losses and dispersion) to study the atmospheric interconnect corrosion under accelerated stress conditions. The picture that emerges from this work shows that the corrosion resilience of the test device is limited by the thermal aging of the passivation layer.
