Abstract:
PROBLEM TO BE SOLVED: To provide a substrate handler, a lithographic apparatus, and a device manufacturing method. SOLUTION: The substrate handler for handling a substrate comprises a conditioning device for conditioning the substrate. The substrate handler is provided with a displacing device configured so as to displace the substrate in the direction substantially parallel to a support surface. The displacing device is configured so as to displace the substrate during the conditioning process from one conditioning position to one or more other conditioning positions. The substrate handler comprises a float device configured to provide an air bed above a support surface of the substrate handler. The substrate handler is configured so as to hold the substrate on an air bed during the conditioning of the substrate. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To provide an actuator assembly easy to assemble, dissassemble, attach and remove. SOLUTION: This actuator assembly includes a coil that can work and can be positioned in a magnetic field generated by a magnet assembly. Virtually only one side surface of each of the coil and the magnet faces the other. In order to generate a force having a primary degree of freedom, magnetized elements are arranged for the purpose of forming the magnetic field so that the magnetic field is nearly perpendicular with respect to the direction of current. As a result, the coil can be attached easily, since there is no need to surround the coil with magnetic poles. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus in which the sensitivity of an influence of a collision on a horizontal plane is reduced. SOLUTION: A lithography projecting apparatus includes a vacuum chamber having a first exhaust means for generating a vacuum beam path for a projecting beam. The projecting apparatus includes a collision protecting device for reducing the influence of the collision of an article table with the wall of the chamber or other article table. These collisions have probabilities of bringing about a software error in a software of the apparatus during a power source failure. COPYRIGHT: (C)2004,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide a bellows for a lithography device which can separate torsional vibrations, force or moments. SOLUTION: The bellows for use in connecting two airtight regions of the lithography device or connecting a region and a pump has a first region having a smooth spiral undulation and a second region capable of absorbing movement in the vertical direction caused by the relative rotation of ends of the first region. The second region can be used as an mirror image of the first region, one of circumferential undulations or as a plurality of subregions.
Abstract:
PROBLEM TO BE SOLVED: To moderate a defect induced by an immersion liquid in an immersion lithography projection apparatus where a liquid removal system surrounds a liquid supply system for providing liquid to a space between a projection system and a substrate. SOLUTION: The liquid removal system 100 is moveable relative to the liquid supply system (partially shown as a barrier member 12) and is controlled to have substantially zero velocity relative to the moving substrate table. The gap between the liquid supply system (partially shown as the barrier member 12) and the liquid removal system 100 may be covered and the atmosphere between the liquid supply system and the liquid removal system above the substrate table may be maintained so that the vapor pressure of liquid is relatively high.

Abstract:
PROBLEM TO BE SOLVED: To provide a substrate handler capable of functioning more efficiently. SOLUTION: The substrate handler 12 is adapted to load a substrate 8 onto a substrate table 6 before exposure and to unload the substrate 8 from the substrate table 6 after exposure. The substrate handler 12 includes at least one support surface adapted to simultaneously convey a plurality of independent substrates 8, 8, or platforms 14, 16. The substrate handler 12 moves the substrate 8 with respect to the substrate table 6 of a lithographic apparatus. COPYRIGHT: (C)2010,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a lithography, including a light weight carriage for a lithographic device with a large rigidity and having full cooling characteristics and arranging characteristics. SOLUTION: There is provided a lithographic device, having a lighting system for adjusting a radiation beam, an article support member for supporting an article placed in the beam path of the radiation beam, and a lithography device having a movable carriage for moving the article support member. The carriage includes a compartmented compound structure, having a non-compound mounting interface and/or cooling interface. With this structure, for example, interface using metal or ceramic materials can be used in combination with an advantage of the compound structure, such as low specific gravity and high Young's modulus at a position and in a direction requiring high strength and high stability and high electrical resistance.

Abstract:
PROBLEM TO BE SOLVED: To provide a liquid immersion lithographic apparatus that prevents an adverse effect on pattern image quality due to existence of bubbles in immersion liquid. SOLUTION: The liquid immersion lithographic exposure apparatus minimizes or prevents generation of bubbles in the immersion liquid by reducing a size or a volume of a gap between an object and the top of a substrate table and/or preparing a cover plate covering the gap. Additionally, an actuator for laterally moving the object in a hole in order to reduce the gap between an edge of the object and a side of the hole of the support table when the object and the table are in contact with the liquid, may be prepared.
