Popis: In this paper, HfN on Si(100) has similar growth quality and electrical resistivity as HfN on MgO(100) (~30 muOmega-cm ), The resistivity values for HfN films on both substrates are much lower than that of TaN and TiN. Preliminary Cu diffusion test along with its low resistivity suggest that cubic HfN can be a promising candidate for Cu diffusion barriers.
