  • Fabrication of metallic microstructures by micromolding nanoparticles
    Patent number: 6472459
    Abstract: A method is provided for fabricating metallic microstructures, i.e., microcomponents of micron or submicron dimensions. A molding composition is prepared containing an optional binder and nanometer size (1 to 1000 nm in diameter) metallic particles. A mold, such as a lithographically patterned mold, preferably a LIGA or a negative photoresist mold, is filled with the molding composition and compressed. The resulting microstructures are then removed from the mold and the resulting metallic microstructures so provided are then sintered.
    Type: Grant

    Date of Patent: October 29, 2002
    Assignee: Sandia Corporation
