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.
