PROBLEM TO BE SOLVED: To provide a support structure for supporting a patterning device and/or table, and an improved material for a substrate table for holding a substrate in a lithographic apparatus, and also to provide a method of manufacturing the same. SOLUTION: A substrate table or a patterning device support includes an aerogel. The aerogel may be very light weight, for example the aerogel may have a density between 0.5 and 500 mg/cm 3 , preferably between 1 and 100 mg/cm 3 , and most preferably between 1 and 10 mg/cm 3 . The aerogel may be made from a silica gel. The aerogel made from silica gel may have a density of 1.9 mg/cm 3 , and if the air out of the aerogel is evacuated, even 1 mg/cm 3 .

Abstract:
PROBLEM TO BE SOLVED: To provide a lithography projector decreasing deformation caused by contaminants and the severity of requirements for a plane surface against the rear surface of a plate with a projection and the front surface of a chuck simultaneously by using the plate with the projection between a removable item and a flexible member. SOLUTION: The lithography projector comprises a radiation system for supplying a projection beam of radiation, a supporting structure for supporting a patterning means of making the projection beam patternized by a desired pattern, a substrate table for supporting the substrate, and a projection system for projecting a patternized beam on a target section of the substrate. Further, the projector comprises at least one supporting structure providing at least one flexible member supporting the plate with the projection which supports the removable item used for the lithography projector.

Abstract:
PROBLEM TO BE SOLVED: To disclose a table in which measures are taken to seal between the table and an edge of an object, in use, supported on the table. SOLUTION: In particular, a capillary passage is formed between the object on the table and the table itself. A meniscus pinning feature and/or the presence of an overpressure at the radially inward side of the capillary passage holds the liquid in the passage and helps prevent it from advancing further radially inwardly. The features to perform this function may be associated with or formed in a member surrounding the object. The member may be thermally decoupled from a part of the table. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a support in which measures are taken to reduce bending of a substrate during loading.SOLUTION: A support for an object has a support surface configured to support the object. The support surface includes a main part and a moveable part. The moveable part of the support surface is moveable between a retracted position and an extended position. In the retracted position, the moveable part of the support surface is substantially in the same plane as the main part of the support surface. In the extended position, the moveable part of the support surface protrudes from the plane of the main part of the support surface.

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.

PROBLEM TO BE SOLVED: To achieve a high throughput in the patterning of a medium imprintable on a substrate. SOLUTION: An actuator is disclosed that is equipped with: a body 40 having faces; and a plurality of parallel conduits 44 located in the body 40. Each of the conduits 44 is deformable in response to a proper pressure change in the conduit 44, by increasing the flow of a fluid in the conduit 44 or increasing a static pressure applied to the fluid in the conduit 44. A deformation of the conduit 44 causes a deformation of a face 42. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an immersion lithography projection apparatus in which a liquid removal system surrounds a liquid supply system that supplies a liquid to a space between a projection system and a substrate. SOLUTION: The liquid removal system is capable of moving with respect to the liquid supply system and is controlled so that is has substantially a relative velocity of zero with respect to a moving substrate table. A gap between the liquid supply system and the liquid removal system can be covered and the atmosphere on the substrate table can be maintained so that the liquid vapor pressure becomes relatively high between the liquid supply system and the liquid removal system.

Abstract:
PROBLEM TO BE SOLVED: To uniformize illumination intensity over a cross section of a projection beam by providing an illumination intensity adjusting apparatus for producing a semi shade on a path for the projection beam of a lithography apparatus. SOLUTION: An illumination intensity adjusting apparatus 10 comprises a plurality of blades 11 disposed on a passage for an projection beam PB to project a partial shadow extending across an illumination field IF. These blades are selectively rotated, and increases its effective width perpendicularly to the illumination beam PB to control uniformity. COPYRIGHT: (C)2003,JPO
