Abstract:
1. A nanoimprinting apparatus, comprising: a master template which has a depression/protrusion pattern; a replica template which is manufactured from the master template by an imprinting method; an inspection light source part which radiates inspection light of plane waves; a stage configured to dispose the master template and the replica template so as to be in close proximity with each other; a detection part which detects light of a component different from the plane waves, the light of the component being generated by the plane wave transmitting through the master template and the replica template; a transport unit which transports the replica template from the stage; a holding part which receives the transported replica template from the transport unit and holds the transported replica template; a substrate mounting platform which is disposed opposing the replica template held by the holding part and whereon a substrate is mounted, the substrate being coated with a liquid resin; a pressing part which presses at least one of the replica template and the substrate such that the resin is stamped with the depression/protrusion pattern; an optical system, which is disposed between the detection part, on one side; and the master template and the replica template, on an other side, and in a radiation direction of the inspection light; and a light shielding member, which is disposed at a pupil position of the optical system and which blocks the plane waves.
