An imprint lithography apparatus comprising a template (34), a substrate table (31) and an alignment system. (35, 36, 37) arranged to align. the template (34) to a substrate alignment t mark (39; 39`) provided on a substrate (30). The substrate table (31) is arranged to support the substrate (30) having a first surface (32) to be imprinted andd a second surface (50) facing the substrate table (31). The apparatus is characterised in that the substrate alignment mark (39; 39') is provided on the second surface (50) of the substrate (30), and that the substrate table (31) further comprises a substrate table optical. system for allowing the substrate alignment mark (39; 39') to be viewed by the alignment system. (35. 36, 37). The invention further extends to a device manufacturing method and a device manufactured thereby. |
