Abstract:
1. An apparatus for performing automated fluid pressure imprint lithography on a substrate having a moldable surface comprising: a source of pressurized fluid; a pressure chamber for receiving the pressurized fluid and to apply the pressurized fluid to the sealed mold and substrate to press the molding surface into the moldable surface: a mold having a molding surface having a protruding feature for molding the moldable surface of the substrate, and the mold positionable with the molding surface adjacent the moldable surface and the pressure chamber positioned for providing pressurized fluid from the source to press the molding surface into the moldable surface; positioners for moving the mold and the substrate relative to each other; a sensor providing an output related to the relative positions of the mold and the substrate means for sealing the interface between the mold and the substrate; and a controller coupled to the positioners, the sensor and the source of pressurized fluid for aligning the mold and the substrate prior to sealing and for imprinting the aligned mold into the substrate after sealing by controlling the introduction of pressurized fluid from the source into the chamber.
