ABSTRACT:
An imprint process comprises the step of aligning a substrate, supported on a first support member, with a template, supported on a second support member. The substrate has at least one essentially plane surface provided with a moldable film. The template has at least one essentially plane surface provided with a relief pattern. The relief pattern is adapted to interact with the moldable film. The process further comprises the step of arranging a sealing gasket between the template and the second support member, such that a pressure cavity is defined by the second support member, the template and the sealing gasket. The process also comprises the step of applying a static gas pressure to the pressure cavity, in order to provide a pressure between the template and the substrate. The pressure is sufficient to form a pattern in the moldable film. An imprint device is also disclosed.
