Abstract:
1. A nano-imprint lithography system for patterning first and second substrates, the system comprising: a nano-imprint mold assembly; a translation stage spaced-apart from the nano-imprint mold assembly; first and second fluid dispensers constructed to position nano-imprint fluid on the first and second substrates, respectively; a first substrate chuck coupled to the translation stage, the first substrate chuck constructed to provide for positioning of the first substrate thereon, the first substrate chuck having a surface with a cavity formed therein and configured such that polymeric material formed on a surface of the first substrate may be positioned within the cavity; a second substrate chuck coupled to the translation stage, constructed to provide for positioning of the second substrate thereon, the second substrate chuck having a surface with a cavity formed therein and configured such that polymeric material formed on a surface of the second substrate may be positioned within the cavity; wherein the translation stage is constructed to alternatively place the first and second substrate chucks in first and second positions with respect to the nano-imprint mold assembly such that the nano-imprint mold assembly may imprint a pattern on one of the first and second substrates while concurrently obtaining a desired spatial relationship to position the remaining substrate of the first and second substrates upon either the first or second substrate chuck; and with the system being calibrated such that the first and second substrate are subjected to substantially the same process conditions.
