Epitaxial SrRuO{sub 3}/SrTiO{sub 3} (001) thin films with a TiN template layer have been deposited on Si(001) single crystal substrates by rf sputtering. The epitaxial orientation relationship was determined to be cube on cube with respect to Si and the crystal quality of the SrRuO{sub 3}/SrTiO{sub 3} film is preserved even when the TiN template layer was oxidized into anatase phase of TiO{sub 2} during the sputtering process of SrRuO{sub 3}. The effect of oxygen plasma on the oxidation and delamination of the TiN layer has been studied using transmission electron microscopy (TEM). The stress in the thin film of SrRuO{sub 3}/SrTiO{sub 3}/TiN structure was determined from the buckle shape in both plan view and cross-sectional TEM images. The critical stress and the compressive stress were estimated to be 2 and 4 GPa.
