  • Patent number: 7049044
    Abstract: The present invention provides new high resolution nanocomposite resists applicable to next generation lithographies, methods of making these novel resists, and methods of using these new resists in lithographic processes to effect state-of-the-art lithographies. New nanocomposite negative resists comprising a photoacid generating component, a styrene component, and an optional polyhedral oligosilsequioxane component are provided. Negative resists of this invention may also contain an optional methacrylate component. This invention and the embodiments described herein constitute fundamentally new architectures for high resolution resists.

  • Publication number: 20050014098
    Abstract: This invention relates to biomaterials, biocompatible photoresists, and electroactive photoresists, and methods to engineer the interactions between biomaterials and cells. In one aspect, this invention provides for modifying surface topography through micro-patterning techniques that require no organic solvent development to reveal the lithographic patterns. Cells can be cultured on these surfaces directly and exhibit strong cell alignment features.
