Patents by Inventor Charles Daniel Schaper

Charles Daniel Schaper has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7981814
    Abstract: A method for the duplication of microscopic patterns from a master to a substrate is disclosed, in which a replica of a topographic structure on a master is formed and transferred when needed onto a receiving substrate using one of a variety of printing or imprint techniques, and then dissolved. Additional processing steps can also be carried out using the replica before transfer, including the formation of nanostructures, microdevices, or portions thereof. These structures are then also transferred onto the substrate when the replica is transferred, and remain on the substrate when the replica is dissolved. This is a technique that can be applied as a complementary process or a replacement for various lithographic processing steps in the fabrication of integrated circuits and other microdevices.
    Type: Grant

  • Patent number: 7125639
    Abstract: A method for the fabrication of patterned devices, in which a latent image is initially formed in a photosensitive material on a carrier, and the exposed material containing the latent image is physically transferred to a substrate before processing. Physical transfer is enhanced by the appropriate selection of coating surface properties and additional coating layers, and by processing steps, such as heating and UV exposure, to promote adhesion to the substrate and detachment from the carrier.
