Abstract:
1. An imprinting apparatus, comprising: a substrate holder configured to hold a substrate; a template holder configured to hold a template, the template holder being operable to cause the template to contact an imprintable medium on a target region of a first surface of the substrate to form an imprint in the medium and to cause the template to separate from the imprinted medium, wherein in the absence of a compensating force, the template holder, in use, causes the substrate to deform by the template contacting the imprintable medium; and a compensating member operable to apply a compensating force; during the template contacting the imprintable medium, to a corresponding location of a second surface of the substrate which is opposite to the first surface so as to reduce deformation of the substrate caused by the template contacting the imprintable medium, wherein the compensating member is operable to provide a compensating force which is substantially equal to or greater than an imprinting force applied to the template to contact the medium to form the imprint in the medium.
