Abstract:
PROBLEM TO BE SOLVED: To provide a load lock with temperature regulation, a lithography system equipped with a load lock, and a method for producing a substrate using the load lock. SOLUTION: An object, e.g. a substrate W, is transferred into/from a lithography system. Load lock outer walls 38 and 40 define at least a part of the load lock volume for containing support units 33 and 141 which support the object W when it is in the load lock. Furthermore, the load lock has a structure for temperature regulation to control the temperature of the object at least before it is transferred from the load lock toward the lithography system.

Abstract:
PROBLEM TO BE SOLVED: To increase the throughput of a lithography projection assembly. SOLUTION: The lithography projection assembly comprises at least one load-lock for transferring an article, especially a substrate, between a first environment and a second environment preferably having a pressure lower than that in the first environment, an article handler including a handler chamber which can be reached by the second environment, and a lithography projector including a projection chamber. The handler chamber and the projection chamber can be interconnected in order to transfer an article. The load-lock comprises a load-lock chamber, a means for exhausting the load-lock chamber, and a door means for closing the load-lock chamber during exhaust operation and opening the load-lock chamber in order to feed the article into the load-lock chamber or taking out the article therefrom. The load-lock chamber is provided with at least two positions for supporting different articles. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To solve a problem of contamination to a liquid immersed lithographic apparatus introduced via immersion liquid or via another mechanism. SOLUTION: The method for cleaning liquid immersed lithographic apparatus utilizes an aerosol spray to be guided to the surface to be cleaned. The aerosol spray utilizes an inert gas such as nitrogen or carbon dioxide, and as a solid or a liquid, water such as ultrapure water, another solvent or a cleaning fluid. Spray from the aerosol is enclosed in a space. If the aerosol collides with the surface to be cleaned, contaminated substances are removed. The removed contaminating substances are guided to an aerosol spray orifice or an outlet together with substances discharged from the outlet (a gas and a liquid and/or a solid).

Abstract:
PROBLEM TO BE SOLVED: To provide a liquid-flowing conduit system, especially a liquid-flowing conduit system of an immersion system wherein vibration caused by liquid compression in a pump chamber and vibration caused by liquid flow or liquid compression are reduced. SOLUTION: The conduit system for a lithographic apparatus includes at least one conduit for guiding a liquid or liquid/gas mixture, and a gas injection nozzle configured to introduce a gas in the liquid or liquid/gas mixture to at least partially absorb pressure peaks or waves in the liquid or liquid/gas mixture. In an embodiment the gas injection nozzle is arranged in a pump of the conduit system. The pump further includes a pump inlet, a pump outlet and the pump chamber between the pump inlet and the pump outlet for compression of the liquid or liquid/gas mixture. COPYRIGHT: (C)2008,JPO&INPIT

Abstract:
A load lock for a lithographic apparatus is arranged to transfer an object, like a substrate, into and from the lithographic apparatus. The load lock outer wall defining at least part of a load lock volume accommodating a support unit for supporting the object when in the load lock. The load lock also has a temperature conditioned structure to control the temperature of the object to a desired temperature at least before the object is transferred from the load lock towards the lithographic projection apparatus.
Abstract:
A method of and apparatus for maintaining a machine part arranged in an interior space of a machine, where the interior space is kept at a first pressure and is separated from an environment having a second pressure via a load lock. The method includes transporting a machine part via the load lock out of the interior space and transporting via the load lock into the interior space one of the maintained machine part and a separate replacement machine part.
Abstract:
Conduit System for a Lithographic Apparatus, Lithographic Apparatus, Pump, and Method for Substantially Reducing Vibrations in a Conduit System A conduit system for a lithographic apparatus includes at least one conduit for guiding a liquid or liquid-gas mixture, and a gas injection nozzle configured to introduce a gas in the liquid or liquid-gas mixture to at least partially absorb pressure peaks or waves in said liquid or liquid-gas mixture. In an embodiment the gas injection nozzle may be arranged in a pump of the conduit system. The pump further includes a pump inlet, a pump outlet and a pump chamber between the pump inlet and the pump outlet for compression of the liquid or liquid-gas mixture.
Abstract:
A load lock is constructed and arranged to transfer a substrate between a first environment and a second environment and to maintain each of the first environment and the second environment therein. The load lock includes a load lock chamber provided with at least two mutually distinct substrate supports positioned one above the other. Each of the substrate supports includes a substrate displacement element. The load lock also includes an evacuation device constructed and arranged to evacuate the load lock chamber, and a door constructed and arranged to close the load lock chamber during evacuation and for opening the load lock chamber.
