Abstract:
PROBLEM TO BE SOLVED: To disclose a substrate support constituted to support a substrate for immersion lithographic processing. SOLUTION: The substrate support has a central part and a peripheral part, the peripheral part includes an extraction duct for extracting a liquid from an upper surface of the substrate support, and extraction duct is connected to an exit duct for duct the liquid away from the substrate support. The substrate support further includes a thermal decoupler for decreasing heat transmission between the central part and the peripheral part. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a liquid immersion lithographic apparatus which reduces bubbles in an immersion liquid to prevent an adverse effect on pattern image quality. SOLUTION: The liquid immersion lithographic apparatus is provided to minimize bubbles generated or to prevent bubbles from being generated in the immersion liquid by reducing sizes or volumes of gaps between a target object and a substrate support table, and their upper structures, in the liquid immersion lithographic apparatus, and/or preparing a cover plate covering the gaps. The liquid immersion lithographic apparatus may further include an actuator which laterally moves the target object in a hole of the substrate support table to reduce a gap between a peripheral end of the target object and an inner side of the hole when the target object is in contact with the immersion liquid.

Abstract:
PROBLEM TO BE SOLVED: To provide a lithography apparatus capable of efficiently sealing liquid between different regions on a substrate table. SOLUTION: The substrate table includes a cover plate 100 disposed on the top surface of a substrate table body MB. Having a flat and continuous top surface, the cover plate 100 can be applied to a local region-type liquid supply system. The top surface of the cover plate 100 is substantially coplanar with that of a substrate W. This makes it possible to install a seal projection portion 200 for reducing or protecting the entry of liquid into a recess between a substrate support SS and the substrate table body MB. The seal projection portion 200 connects between the bottom internal edge of the cover plate 100 and the top surface of the substrate support SS. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide lithography equipment which can efficiently seal a liquid between different regions of a substrate table. SOLUTION: The substrate table is provided with a cover plate 100 which is arranged above a main body MB of the substrate table. The cover plate 100 which has is a flat and continuous upper surface can be applied to a local region type liquid feed system. The upper surface of the cover plate 100 is approximately the same plane as the upper surface of a substrate W. A sealing projection 200 may be formed to reduce or prevent liquid to enter a recess between a substrate support SS and the main body MB of the substrate table. The sealing projection 200 connects the interior edge of the cover plate 100 and the upper surface of the substrate support SS. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
A lithographic apparatus includes an illumination system for providing a beam of radiation and a support structure for supporting a patterning device. The patterning device serves to impart the beam with a pattern in its cross-section. The lithographic apparatus includes a substrate table for holding a substrate and a projection system for projecting the patterned beam onto a target portion of the substrate. The apparatus has a chuck system (100) for supporting an object, such as the substrate or the patterning device, in the lithographic apparatus. The chuck system includes a chuck (120) for supporting the object, a frame (110) for supporting the chuck, and a chuck support structure (114) for supporting the chuck relative to the frame. The chuck support structure includes at least one flexure element (130), which flexure element is flexible in at least one degree of freedom and is coupled to the chuck and the frame.
Abstract:
A lithographic apparatus is disclosed in which a circular sensor is mounted to a substrate table with three leaf springs that are evenly spaced around a thermal axis of the sensor. The leaf springs are provided in two parts that are releasably attachable to each other. The leaf springs are elastic and allow some movement of the sensor relative to the substrate table on thermal expansion and contraction but ensure that the thermal center of the sensor does not move relative to the substrate table.
Abstract:
In an immersion lithographic apparatus, bubble formation in immersion liquid is reduced or prevented by reducing a gap size or area on a substrate table and/or covering the gap.
