Abstract:
1. A method of fabricating an imprint stamp, comprising: patterning a substrate; etching the substrate to form a pattern in the substrate; depositing a first layer of material on the substrate; patterning the first layer of material; etching the first layer of material to form a portion of an application specific imprint pattern in the first layer of material, the portion including a variation in a topography of the first layer of material; depositing an additional layer of material on a previously etched layer of material; patterning the additional layer of material; etching the additional layer of material to form an additional portion of the application specific imprint pattern in the additional layer of material, the additional portion including a variation in a topography of the additional layer of material; repeating the depositing, the patterning, and the etching of additional layers of material until the application specific imprint pattern is completely defined and comprises a plurality of features that are defined by the variations in the topographies of all of the layers of material that were deposited, patterned, and etched; segmenting the substrate to form an imprint blank that includes the application specific imprint pattern on an exposed cross-sectional surface thereof; and selectively etching the exposed cross-sectional surface of the imprint blank to form the imprint stamp.
