摘要: Epitaxial TiZrN films were successfully grown on Si (100) substrates at high temperature by using DC magnetron reactive sputtering with a Ti0.68Zr0.32 alloy target. Annealing of a grown TiZrN/Si specimen was performed by applying microwave plasma with a gas mixture of N-2 and H-2 to improve the film quality. The X-ray rocking curve (XRC) width of (200)(TiZrN) reflection can reach a minimum value of 1.18 degrees. The heteroepitaxial relationship of TiZrN with Si is {001}(TiZrN)//{001}(Si) and < 110 >(TiZrN)//< 110 >(Si). The (200)(TiZrN) XRC width of a 20 nm-thick TiZrN film reduces from 1.99 degrees to 0.85 degrees by microwave plasma annealing. As a result of the improvement of the film quality, the annealed film exhibits a much lower resistivity (28 mu Omega.cm) than that of the as-deposited one (44 mu Omega.cm). The surface morphologies of the TiZrN films are smooth with the surface roughness in the range of 1-2 nm.
