ABSTRACT:
Methods are disclosed for making microstructures. In one method, the resist layer is reversibly deformed during exposure. When the resist is flattened and developed after exposure, non-vertical features result that are not obtainable through other existing means. One application of this method is to make nested cones suitable for use as a highly efficient x-ray lens. In another disclosed method, "halftone" lithography is used to generate microstructures having features whose height may vary continuously. One application of this method is to make a novel telescope array, a thin film having telescopic magnification properties.
