  • Method and apparatus for producing biaxially oriented thin films
    Patent number: 7829156
    Abstract: A method and an apparatus serve to produce thin films having a biaxial crystal orientation. The method includes the steps of: depositing atoms on a substrate, the atoms having a composition corresponding to the thin film to be produced; bombarding the deposited atoms with an energized beam, the energized beam being oriented with respect to the substrate at an angle of a defined range of angles, the step of bombarding substantially taking place during a different time period than the step of depositing; and alternately repeating the step of depositing and the step of bombarding for a plurality of times.
