Abstract

Present efforts to minimize the resistivity of copper interconnects are discussed in terms of a comprehensive understanding of microstructure and electron scattering. A general approach for modeling resistivity that includes Monte-Carlo simulation of grain growth, first-principles modeling for grain boundary (GB) and interfacial resistivities, and a stochastic simulation for electron transport is presented. Determination of GB resistivities for Σ3 twin boundaries and Σ5 twist boundaries serve to illustrate steps in this approach.
