摘要:
A lithographic apparatus includes a magnet being contained in a protective enclosure, the protective enclosure being arranged to protect the magnet from contact with a H2-containing or H-atom containing gas. The enclosure may further contain a hydrogen getter, such as a magnet-surface modifying gas, or a non-hydrogen containing gas. A non-hydrogen containing gas flow may be provided or a non-hydrogen getter gas flow may be provided through at least part of the protective enclosure.

The present invention relates to a clamping device configured to clamp an object (20, 120) on a support (1, 101). The clamping device comprises: a first device configured to force the object and the support away from each other using a first force, and a second device configured to force the object and the support towards each other using a second force. The first device and second device are configured to simultaneously exert the first force and the second force respectively to shape the object to a desired shape before completing the clamping of the object on the support.

A lithographic apparatus is disclosed. The apparatus includes an illumination system configured to condition a radiation beam, and a support constructed to support a patterning device. The patterning device is capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam. The apparatus also includes a substrate table constructed to hold a substrate, a projection system configured to project the patterned radiation beam onto a target portion of the substrate, a liquid supply system configured to at least partly fill a space between the projection system and the substrate with liquid, a seal member arranged to substantially contain the liquid within the space, and elements to control and/or compensate for evaporation of immersion liquid from the substrate.

A lithographic apparatus is disclosed that is arranged to project a pattern from a patterning device onto a substrate, the lithographic apparatus has a substrate table configured to hold a substrate. The substrate table includes a conditioning system configured to hold a conditioning fluid and to condition the substrate table. The conditioning system includes a pressure damper that is in fluid communication with the conditioning system and is arranged to dampen a pressure variation in the conditioning system.

A clamping device can be configured to clamp an object on a support. The clamping device can include a first device configured to exert an attracting force on the object, and a second device configured to exert a rejecting force on the object. The first device and second device can be configured to simultaneously exert an attracting and a rejecting force on the object to shape the object to a desired shape before clamping of the object on the support. A method is provided for loading an object on a support, comprising the steps of shaping the object in a desired shape spaced from the support. The shaping can include subjecting the object simultaneously to an attracting force pulling the object toward the support and a rejecting force pushing the object away from the support, and clamping the object on the support.
