PROBLEM TO BE SOLVED: To provide a system for removing a liquid from a substrate table, in particular, from a gap between the substrate table and a substrate, and to provide a method therefor. SOLUTION: In the liquid removing method, the liquid is removed from the substrate held on the substrate table and from the gap between the substrate and the substrate table. A liquid removing device is provided with at least one outlet port, forming a predetermined geometric long and thin extractor; the substrate table is moved relative to the liquid removing device so that the extractor passes all through the substrate and the gap; and that the local tangent in the local portion of the extractor at the end of non-dry portion in the gap substantially holds the angle between about 35° and 90° on a planar view, at arbitrary times with respect to that in the gap.

PROBLEM TO BE SOLVED: To provide a lithographic apparatus and a lithographic method which can reduce passage of air through liquid or contamination of the liquid. SOLUTION: The lithographic apparatus comprises a substrate table for holding a substrate, a projection system for projecting a patterned radiation beam projected on the substrate, a liquid supplying system which supplies liquid to a space between the projection system, the substrate table, and the substrate, and a sealing prepared to the substrate table. The sealing can be operated from opened configuration to closed configuration, and in closed configuration, when a substrate is on the substrate table, the sealing closes a gap between them.

PROBLEM TO BE SOLVED: To provide a lithography apparatus, a lorentz actuator, and a method for manufacturing a device. SOLUTION: The lithography apparatus has an extremely effective lorentz actuator. The lorentz actuator has a conductive element for generating a force by the interaction of a main magnet system and an auxiliary magnet system which are disposed in a haulback configuration with a current carried by a conductive element, and a synthesized magnetic field of first and second magnetic fields generated by the main magnet system and the auxiliary magnet system respectively. The lorentz actuator further has a magnetic element substantially extending between the outside of a first magnet system subassembly and the outside of a second magnet system subassembly. The magnetic element guides part of a second auxiliary magnetic field between the first magnet system subassembly and the second magnet system subassembly. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a low-cost supporting means with a simple structure that is a lithographic projection apparatus and can be used in a vacuum in order to support a balance mass for eliminating vibrations due to a reaction force when moving a substrate table. SOLUTION: The balance mass of a lithographic projection apparatus is supported on a base frame by at least one flexible supporting element that is mechanically attached to this balance mass and the base frame and has at least two pivot points. Since this supporting element has two or more pivot points, this supporting means hardly shows resistance to the horizontal movements of the balance mass BM, so as to allow the balance mass BM to move freely in a horizontal direction. An air bearing is not used, so it can be used even in a vacuum. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a projection apparatus for lithography having a planar magnetic positioning means that can be automatically self-recovered and that suppresses mechanical load applied to guide pipes that are mounted on a substrate table to the smallest extent. SOLUTION: This projection apparatus for lithography has a planar magnetic positioning means with which movement of the substrate table in a plane is accomplished, and a mechanical limiter that limits rotation of the substrate table around a direction normal to the plane.

PROBLEM TO BE SOLVED: To provide a lithographic apparatus whose movable object component can be guided with a gas bearing, to which pressurized gas is supplied by using an improved gas supply mechanism. SOLUTION: The lithographic apparatus which has a track prepared with a plurality of gas flow ejection holes arranged along the track is disclosed. Gas conduits are constituted so that they supply the pressurized gas to the gas flow ejection holes in order to form the gas bearing constituted for supporting the object component movably along the track. Furthermore, a gas flow device is formed that is constituted for generating gas flows which pass through one or more gas flow ejection holes on a guide surface of the object component, or for impeding gas flows which pass through one or more gas flow ejection holes, corresponding to the positional relations between the gas flow ejection holes and positions on the guide surface.
