An improved method of imprint lithography involves using fluid-induced pressure from electric or magnetic fields to press a mold onto a substrate having a moldable surface. The method is characterized in that a tool is applied which comprises an inlet section with a barbed section, which lets the object pass into the holding area, but which prevents the object from being led out of the holding area. The second light-emitting device includes a third light-emitting unit, fourth electrode, fourth light-emitting unit, and fifth electrode.
