    摘要: A lithographic apparatus includes an illumination system configured to condition a radiation beam, a support constructed to support a patterning device capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam, a substrate table constructed to hold a substrate, and a projection system configured to project the patterned radiation beam onto a target portion of the substrate. At least one vibration isolation support device can be provided for supporting an object of the apparatus. The object can be rotatably supported at the vibration isolation support device by way of a rotational support having a center of rotation. The rotational support can have its center of rotation located substantially at the center of gravity of the vibration isolation support device.

    摘要: A lithographic apparatus includes a projection system to project a patterned radiation beam onto a substrate, and a damping system to dampen a vibration of at least part of the projection system, the damping system including an interface damping mass and an active damping subsystem to dampen a vibration of at least part of the interface damping mass, the interface damping mass connected to the projection system, and the active damping subsystem connected to the interface damping mass, the active damping subsystem including a sensor to measure a position quantity of the interface damping mass and an actuator to exert a force on the interface damping mass based on a signal provided by the sensor. The damping system further includes an interface damping device connected to the interface damping mass and configured to damp a movement of the interface damping mass at an eigenfrequency of the interface damping mass.
