Abstract:
1. An imprint lithography apparatus comprising: an imprint template arrangement for use in imprinting a pattern into an imprintable medium provided on a substrate; a substrate holder configured to hold the substrate; an electromagnetic Lorentz actuator arrangement configured to move the imprint template arrangement, the electromagnetic Lorentz actuator arrangement comprising: an array of magnets, and an array of conductors, each conductor configured to carry an electric current, one of the array of magnets or the array of conductors being moveable and connected to the imprint template arrangement, and the other of the array of magnets or the array of conductors extending at least partially around or forming a part of the substrate holder, and the array of magnets and the array of conductors together being in a configuration which facilitates moving of the moveable one of the array of magnets or the array of conductors in six degrees of freedom, such that the imprint template arrangement is also movable in six degrees of freedom.
