Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus having a component that moves in a first direction, the component including a passive gas flow system.SOLUTION: The passive gas flow system has a gas inlet to drive gas into the passive gas flow system when the component moves in the first direction and a gas outlet, connected to the gas inlet by a gas conduit, to direct the gas that is driven into the passive gas flow system in a certain direction.
Abstract:
PROBLEM TO BE SOLVED: To provide, for example, an arrangement which addresses some problems associated with movement of a support.SOLUTION: An apparatus, in an embodiment, has a patterning device support including a first planar element having a first flow-restricting surface; a second planar element including a second flow-restricting surface facing the first flow-restricting surface; a support driver to linearly move the support along a certain direction relative to the second planar element. The first and/or second flow-restricting surface has one or more projections and/or recesses between the first and second flow-restricting surfaces. The projection and/or recess on the first and/or second flow-restricting surface is arranged to provide a flow resistance, per unit width of the first and/or second flow-restricting surface perpendicular to a flow, that is lower against a flow that is parallel to the certain direction than against a flow that is perpendicular to the certain direction. The flow-restricting surfaces may direct a gas flow onto a driver part that generates heat.
Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus that reduces an latent harmful influence of a droplet left on a sensor and/or a target for the sensor. SOLUTION: An immersion lithographic apparatus is disclosed that includes a table having a surface and the sensor, or the target for the sensor, or both, the sensor and/or target having a first area which is lyophobic to immersion liquid and a second area which is lyophilic to immersion liquid, and a liquid displacement device configured to displace liquid on the sensor and/or target, wherein the liquid displacement device includes a gas outlet opening configured to direct a gas flow toward the first and second areas. A property of a part of the gas flow introduced into the first area is different from a property of a part of the gas flow introduced into the second area. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To reduce or eliminate a risk of contamination in a lithographic apparatus.SOLUTION: A gas curtain is provided to separate a component of the lithographic apparatus from contaminated gas. The gas curtain is supplied by an opening. The opening is at a boundary of a protection environment with which a surface of the component comes into contact. The gas curtain may separate the component from a moving part of the apparatus.
Abstract:
PROBLEM TO BE SOLVED: To prevent defect caused by water remaining on a surface where it is difficult to move water while water is not preferable, in a lithographic apparatus. SOLUTION: An immersion lithographic apparatus having a table constituted so as to support a substrate is provided. A sensor or a sensor target is provided on a table surface, and a cover extending from an edge of the table is provided. Furthermore, a liquid moving device including a gas outlet is provided, wherein the gas outlet is constituted so as to guide local gas flow toward the sensor or the target in order to move a liquid from the sensor or the target over the cover and off the table.

Abstract:
A lithographic apparatus including a barrier system and a device manufacturing method using such a lithographic apparatus. The barrier system is used to maintain a protected volume of gas within a barrier. The protected volume may be maintained when different components of the lithographic apparatus move relative to each other. The barrier system may be used in different locations within the lithographic apparatus. The geometry of the barrier affects how efficiently the protected volume is maintained, especially at high speeds. The geometry reduces the amount of ambient gas entering the protected volume from outside the barrier.
