    摘要: Embodiments of the invention generally provide an electron beam substrate processing system. In one embodiment, the present invention provides an electron beam substrate processing system where a spindle shaft used to rotate substrates during processing includes two encoder wheels. One encoder wheel is configured to provide a rotational speed data signal to a rotational speed control system. Another encoder wheel is configured to provide a pattern generator clock signal at a higher frequency than the rotational speed data signal to a pattern generator. In one embodiment of the present invention, at least one of the encoder wheels is positioned adjacent the substrate to minimize torsional and differential movements between the at least one encoder wheel and the substrate.

    摘要: A stamper/imprinter for use in performing thermal imprint lithography of a substrate/workpiece surface to form a pattern of features in first portions of the surface intended to receive the pattern, without incurring random formation of undesired, disordered features in second portions of the substrate/workpiece surface not intended to receive the pattern, comprising an imprinting surface configured to substantially prevent formation of gaps between the imprinting surface and the second portions of the surface during stamping/imprinting. Embodiments include stampers/imprinters with a multilevel imprinting surface comprises a first portion having a first level for forming the pattern of features in the first portions of the surface and a second portion having a second level for substantially preventing formation of gaps between the imprinting surface and the second portions of the surface during stamping/imprinting.
