摘要: N thin films as barrier layer for memory devices application were deposited by reactive magnetron sputtering. The crystallinity, micro-structure, oxidation resistance and mechanism of investigated a function Al content. Lattice parameter grain size decreased with increasing the content Oxidation film higher is slow then, total oxide thickness thinner than that lower film. Oxide formed on surface AlTiNO layer. / diffusion limited process time increased parabolic law. activation energy oxygen diffusion, Ea coefficient, D /XN 2.1eV ~ /s, respectively. XN showed good resistance.
