Abstract:
1. An imprint process, comprising the steps of: aligning a substrate, supported on a first support member, with a template, supported on a second support member, said substrate having at least one essentially plane surface provided with a moldable film, said template having at least one essentially plane surface provided with a relief pattern, and said relief pattern facing said moldable film; arranging a first sealing gasket between said template and said second support member, such that a pressure cavity is defined by said second support member, said template and said first sealing gasket; and applying a static gas pressure to said pressure cavity, in order to press said template and said substrate together, so as to transfer the relief pattern of said template onto said moldable film, wherein said static gas pressure is held at a pressure higher than that of the surrounding environment for a time sufficient to transfer the relief pattern of said template onto said moldable film.
