Imprint apparatus control, control method and manufacturing method
摘要:
An apparatus and method configured to brake and/or dampen an imprint head. The apparatus and method includes a mount attached to a fixed surface, a movable plate movable relative to the mount and configured to hold and move an imprint template or superstrate, at least one electromagnetic actuator with a first electrical terminal and a second electrical terminal, mounted between the movable plate and the mount, wherein an electrical current is applied to the at least one electromagnetic actuator for controlling movement of the moveable plate, an inductance serially connected at the first electrical terminal of the at least one electromagnetic actuator to control the electrical current, and at least one switch serially connectable to the second terminal of the at least one electromagnetic actuator and a terminal of the inductance to switch between a state where the inductance acts upon the at least one electromagnetic actuator or a state where the inductance does not act upon the at least one electromagnetic actuator.
