In this work, the optimized process condition of chemical solution deposition which is used to planarize the surface of the metal tape (which is used to grow IBAD-MgO texture template) was investigated. Y20 3 films were dip-coated on the surface of the unpolished metal tape as the seed and barrier layer. The effects of Y 203 concentration of the solution (0.5wt. %, 1.3wt. %, 2.8wt. %, 5.6wt. %) and the number of coatings on the surface morphology and barrier capability against the diffusion from the metal tape were examined. The surface morphology and the thickness of the film were observed using the scanning electron microscope and the atomic force microscope. The presence of elements in metal tape on the film surface was analyzed using the auger electron spectroscopy. The Y20 3 film thickness increases with increasing the Y20 3 concentration in the solution, and the surface became smoother with increasing the number of coating cycles. The best result was obtained from the Y20 3 film coated 4 cycles using 2.8wt. % solution.
