Electromagnetic actuator, method of manufacturing a part of an electromagnetic actuator, and lithographic apparatus comprising and electromagnetic actuator |
摘要 |
A lithographic apparatus has a patterning support constructed to support a patterning device and a substrate support constructed to support a substrate. At least one of the patterning support and the substrate support is moved by an electromagnetic actuator. The actuator has a first part and a second part that are movable relative to each other. The first part has a coil structure, and the second part including a plurality of permanent magnets interacting with the coil structure. The second part is provided with a cooling structure arranged adjacent the permanent magnets. Cooling ducts are arranged between adjacent permanent magnets, or on a side of the permanent magnets facing the coil structure.
