  • Patent number: 6632285
    Abstract: An apparatus for simultaneously depositing gradients components of two or more target materials onto a substrate is disclosed. The apparatus comprises a first target material source that directs a first target material towards the substrate and a second target material source that directs a second material towards the substrate. The apparatus further comprises a gradient shutter system that blocks a first predetermined amount of the first target material and a second predetermined amount of the second target material directed towards the substrate in order to generate gradients of the first and second target materials on the substrate. The gradients of the first and second target materials being simultaneously deposited onto the substrate to form a homogenous resulting material. A method for simultaneously depositing gradients of two or more target material onto a substrate is also disclosed.
    Type: Grant

  • Patent number: 6045671
    Abstract: Methods and apparatus for the preparation of a substrate having an array of diverse materials in predefined regions thereon. A substrate having an array of diverse materials thereon is generally prepared by depositing components of target materials to predefined regions on the substrate, and, in some embodiments, simultaneously reacting the components to form at least two resulting materials. In particular, the present invention provides novel masking systems and methods for applying components of target materials onto a substrate in a combinatorial fashion, thus creating arrays of resulting materials that differ slightly in composition, stoichiometry, and/or thickness. Using the novel masking systems of the present invention, components can be delivered to each site in a uniform distribution, or in a gradient of stoichiometries, thicknesses, compositions, etc.

  • Patent number: 5820678
    Abstract: A system for MOCVD fabrication of superconducting and non-superconducting oxide films provides a delivery system for the feeding of metalorganic precursors for multi-component chemical vapor deposition. The delivery system can include multiple cartridges containing tightly packed precursor materials. The contents of each cartridge can be ground at a desired rate and fed together with precursor materials from other cartridges to a vaporization zone and then to a reaction zone within a deposition chamber for thin film deposition.
