Patent ID: 8025829

Claim:
A method of imprint lithography to provide step-and-repeat imprint replication on a moldable surface of a substrate of a pattern having microscale or nanoscale features comprising the steps of: a). providing the substrate having the moldable surface; b). providing the mold having a molding surface that is for molding the pattern, the molding surface smaller in lateral area than said substrate; c). providing a body facing said molding surface of said mold; d). disposing said substrate in a laterally movable positioner between said mold and said body wherein said moldable surface faces said molding surface; e). pressing both sides of said substrate at opposing locations with said mold and said body by opposing transverse forces that are balanced; f). at least partially hardening the moldable surface; g). removing said mold and said body from said substrate; h). laterally moving said movable positioner and said substrate relative to said mold and said body; and i). repeating step e to step g at least once.
