Patents by Inventor Susan L. Brandow

Susan L. Brandow 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: 6773865
    Abstract: This invention discloses an anti-charging layer for beam lithography and mask fabrication. This invention reduces beam displacement and increases pattern placement accuracy. The process will be used in the beam fabrication of high-resolution lithographic masks as well as beam direct write lithography of electronic devices. The anti-charging layer is formed by the use of metal films bound to metal ligating self-assembled monolayers (SAMs) as discharge layers.
    Type: Grant
    Filed: April 15, 2003
    Date of Patent: August 10, 2004
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Elizabeth Dobisz, Walter J. Dressick, Susan L. Brandow, Mu-San Chen

  • Patent number: 6436615
    Abstract: An aspect of the present invention is a process for modifying a substrate in areas that are exposed to actinic radiation, having the steps: (a) providing on the substrate functional groups adapted for conversion to oxygen-containing photoproducts upon exposure to actinic radiation; (b) exposing at least a portion of the substrate to the actinic radiation, converting the functional groups in an exposed region of the substrate to the photoproducts; (c) contacting the photoproducts with a primary or secondary amine in the presence of hydrogen ions, forming imine groups; and (d) contacting the imine groups with a reducing agent, forming amine groups on the substrate in the exposed region.
