  • Direct writing of metallic conductor patterns on insulating surfaces
    Patent number: 7208193
    Abstract: A method for direct writing an electrically conductive metallic feature on an insulating substrate comprises creating a gas jet comprising metallic particles (301), ejecting the gas jet comprising metallic particles through a straight bore tube (302), and impacting the gas jet comprising metallic particles onto a substrate to impinge the metallic particles on the substrate to form the electrically conductive metallic feature (303).
    Type: Grant
    Filed: September 26, 2003
    Date of Patent: April 24, 2007
    Assignee: Research Foundation of the State University of New York
    Inventors: Richard Gambino, Robert Greenlaw, Shaun Kubik, Jon Longtin, Joshua Margolies, Sanjay Sampath

  • Method and apparatus for fine feature spray deposition
    Patent number: 6576861
    Abstract: A system for fine feature spray deposition includes a substrate platform for supporting a substrate on which the features are to be deposited. A spray assembly is provided which includes a spray source for providing a stream of material to be deposited on a substrate, a collimator which is positioned in a path of the stream from said spray source and an aperture assembly, which is positioned downstream of the collimator with respect to the spray source and above the substrate platform. The aperture assembly defines at least one opening to pass a portion of the stream of material onto a surface of the substrate. A drive mechanism is provided which is coupled to at least one of the spray assembly and the substrate platform for inducing relative motion there between. A controller is coupled to the spray assembly and the drive mechanism to control the relative motion and the stream of material. The system allows fine features to be printed directly on a substrate with requiring a predefined mask.
