Abstract:
1. A parallelism adjustment device applicable to nano-imprint lithography, the device comprising: an imprint unit at least having a first molding plate and an imprint mold mounted on the first molding plate; a carrier unit at least having a second molding plate, a suction plate mounted on the second molding plate, and a substrate mounted on the suction plate and held thereto using suction, wherein a moldable layer is coated on the substrate; a parallelism adjustment mechanism comprising a hermetically enclosed resilient film and a predetermined amount of fluid filled therein, wherein the parallelism adjustment mechanism is coupled to at least one of the first and second molding plates; and a driving source for driving at least one of the imprint unit and the carrier unit, to allow the imprint mold to come into contact with the moldable layer to perform imprinting, and to allow the parallelism adjustment mechanism to be pressed via the contact between the imprint mold and the moldable layer so as to adjust parallelism for the imprint mold and the substrate with respect to each other.
