摘要

Interface properties of La-silicate gate dielectrics with tungsten carbide gate electrode have been investigated. Utilizing multi-stacking of tungsten and carbon thin films, W_2C was found to be formed on n-Si (100) by annealing at 750 °C for 20 minutes in N_2 ambient. Improvements in interface properties have been observed using W_2C gate electrode.
