  • PRODUCTION OF GLANCING ANGLE DEPOSITED FILMS
    Publication number: 20150140213
    Abstract: Method and apparatus for producing glancing angle deposited thin films. There is a source of collimated vapour flux, the source of collimated vapour flux having a deposition field; and a travelling substrate disposed within the deposition field of the source of collimated vapour flux, the collimated vapor flux being collimated at a defined non-zero angle to a normal to the travelling substrate.
