Abstract
The composition of Y–Ba–Cu–O thin films deposited by RF sputtering was found to depend strongly on the substrate location and accumulated sputtering time, if a stoichiometric compound target was used. The film is seriously off-stoichiometric, with Ba being deficient, and Cu and Y in excess not only for the centered substrate, but also for the off-centered substrate. However, after prolonged sputtering, stable conditions can be obtained and a right film composition achieved for the off-centered substrate. A more powerful technique for obtaining stoichiometry in as-deposited thin films can be realized by arranging the substrate perpendicular to the target. The accumulated sputtering time for obtaining reproducible stoichiometric, as-deposited films is directly related to the substrate location. A stoichiometric thin film was obtained during the first deposition from a new target and repeated in many following runs.
