Nanoworld Semiconductor Industry - State and Future Challenges of Technology Computer Aided Design

摘要

Several application examples of nanoscale techniques used to influence or enhance the understanding of material properties as well as processing behavior are presented. We will also present a review of first principle density functional theory calculations used to investigate the scaling trends of high-k gate dielectrics. Since conventional as well as high-k dielectrics may still require a strong diffusion barrier against boron penetration we will present ab-initio quantum chemical calculations for the diffusion of boron within a thin gate oxide layer. Plasma-nitridation can be applied to alter the diffusion behavior of boron inside the gate oxide dielectric and to completely block boron penetration. We will present a detailed view on the nitridation mechanism and a combination of reactor-feature scale simulations in combination with Monte Carlo implantation simulations to describe the nitridation process. Finally, kinetic Monte Carlo applications are presented for diffusion pro-cesses.
