Abstract
Apparatus and method for transferring a pattern from a template () having a structured surface to a substrate () carrying a surface layer of a radiation polymerisable fluid (). The apparatus comprises a first main part () and a second main part () having opposing surfaces (), means for adjusting a spacing () between said main parts, support means () for supporting said template and substrate in mutual parallel engagement in said spacing with said structured surface facing said surface layer, a radiation source () devised to emit radiation into said spacing. A cavity () has a first wall comprising a flexible membrane () devised to engage said template or substrate, and means () are provided for applying an adjustable overpressure to a medium present in said cavity, whereby an even distribution of force is obtained over the whole of the contact surface between the substrate and the template.
