PROBLEM TO BE SOLVED: To provide a lithographic apparatus reducing latent adverse effect of liquid drops remained on a substrate table after light-exposure of a substrate. SOLUTION: The lithographic apparatus having a table including a target and/or a sensor and a liquid displacement device displacing a liquid from the target and/or the sensor using a localized gas flow is disclosed. The liquid displacement device can be disposed at various positions. For example, the liquid displacement device can be mounted on a liquid handling device at a light-exposure station and can be disposed adjacent to a transfer passage between the light-exposure station and a measuring station or adjacent to a load/unload station or the sensor in the transfer passage.

PROBLEM TO BE SOLVED: To provide a sealing member or barrier member which reduces a turbulent flow and reduces overflowing of an immersion liquid in a liquid supply system used for an immersion lithographic apparatus. SOLUTION: The liquid supply system used for the immersion lithographic apparatus provides a laminar flow of immersion liquid between a final element of a projection system and a substrate. A control system minimizes the changes of overflowing and an extractor includes an array of outlets configured to minimizes vibrations. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a system that efficiently and effectively eliminate energy loss in a lithographic apparatus where a related component is locally cooled by evaporation of a supplied liquid and may be deformed and change in quality to possibly cause defocusing and lens aberrations during immersion lithography in which the part between a projection system and a substrate is filled with an immersion liquid so as to increase a numerical aperture. SOLUTION: A schedule table 34 is prepared which contains information regarding time when the supplied liquid 11 is most apt to evaporate, the position, speed, acceleration, etc. of the substrate, and a liquid evaporation controller 30 heats at least part of the substrate W by a heater or sends humidifying air according to the schedule table 34 to prevent local evaporation.

Abstract:
PROBLEM TO BE SOLVED: To disclose a lithography apparatus comprising a substrate table, a projection system, a liquid confinement structure and a thermal measurement system. SOLUTION: The substrate table supports a substrate. The projection system induces a patterned radiation beam to a target portion of the substrate. The liquid confinement structure confines immersion liquid at least partially to a space between the projection system and the substrate and/or substrate table, or between the both of them. The thermal measurement system includes thermosensitive coating. The thermal measurement system 100 detects a temperature of the immersion liquid contacting the coating. The thermal measurement system, metrology system having the thermal measurement system, and a dummy wafer for the thermal measurement system are also disclosed. COPYRIGHT: (C)2010,JPO&INPIT

Abstract:
A lithographic apparatus including a substrate table position measurement system and a projection system position measurement system to measure a position of the substrate table and the projection system, respectively. The substrate table position measurement system includes a substrate table reference element mounted on the substrate table and a first sensor head. The substrate table reference element extends in a measurement plane substantially parallel to the holding plane of a substrate on substrate table. The holding plane is arranged at one side of the measurement plane and the first sensor head is arranged at an opposite side of the measurement plane. The projection system position measurement system includes one or more projection system reference elements and a sensor assembly. The sensor head and the sensor assembly or the associated projection system measurement elements are mounted on a sensor frame.

Abstract:
LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD Various types of pressure regulating devices are disclosed to reduce a pressure gradient in a liquid supply system of a lithographic apparatus, the liquid supply system having a liquid confinement structure configured to at least partially confine a liquid between a projection system and a substrate table of the lithographic apparatus. A high pressure gradient may cause particulate contamination in the liquid supply system and/or liquid confinement structure. A pressure gradient can be reduced by, for example, the use of slow switching in one or more valves, a bleed flow around or through one or more valves, diversion of liquid to a drain rather than or in addition to switching a valve off, a pressure regulator or flow restrictor to prevent shock waves, and a buffer volume / damper to compensate for pressure fluctuation.
