  • MATERIAL SUPPLY SYSTEM AND METHOD
    Publication number: 20070007109
    Abstract: A system and a method for feeding a solid into a solid deposition system is described. Solid contained in a hopper is directed into a vibratory bowl. The frequency of the vibrations of the vibratory bowl can be modulated by a feedback system. The solid can then be entrained in a carrier gas which can flow to a distributor for deposition on a substrate.

  • SYSTEM AND METHOD FOR DEPOSITING A MATERIAL ON A SUBSTRATE
    Publication number: 20060236939
    Abstract: A method and apparatus for depositing a film on a substrate includes introducing a material and a carrier gas into a heated chamber. The material may be a semiconductor material, such as a cadmium chalcogenide. A resulting mixture of vapor and carrier gas containing no unvaporized material is provided. The mixture of vapor and carrier gas are remixed to achieve a uniform vapor/carrier gas composition, which is directed toward a surface of a substrate, such as a glass substrate, where the vapor is deposited as a uniform film.
