Patent ID: 8142850

Claim:
A method of patterning a substrate comprising a plurality of fields, said method comprising: positioning a first volume of fluid on a first subset of said plurality of fields of said substrate, with said first volume of fluid being subjected to a first evaporation time, said first evaporation time being a time between positioning said first volume of fluid on said first subset and patterning said first subset; positioning a second volume of fluid on a second subset of said plurality of fields of said substrate, differing from said first subset, with said second volume of fluid differing from said first volume of fluid and being subjected to a second evaporation time, differing from said first evaporation time, said second evaporation time being a time between positioning said second volume of fluid on said second subset and patterning said second subset; and patterning using an imprint lithography template said first volume of fluid on said first subset of said plurality of fields defining a first patterned layer on said substrate, the first patterned layer having a volume; and, patterning using the imprint lithography template said second volume of fluid on said second subsets of said plurality of fields defining a second patterned layer on said substrate, the second patterned layer having a volume, wherein said first volume of fluid and said second volume of fluid are determined relative to the first and second evaporation times such that said volume associated with said first patterned layer is substantially same as said volume associated with said second patterned layer.
