Abstract:
PROBLEM TO BE SOLVED: To disclose and provide an apparatus that is equipped with a substrate table for supporting substrate. SOLUTION: A supporting table includes a plurality of supporting protrusions, coming into contact with a substrate when used to support the substrate. This support table includes a plurality of heat transfer protrusions, extending toward the substrate without making contact with the substrate, when the substrate is supported by the supporting protrusions during use. A heat exchange gap, containing a gas for exchanging heat with the substrate, extends between the heat transfer protrusions and the substrate. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To vary fluid pressure by accelerating a substrate table and accelerating regulating fluid in a supplying device, in a removing device and/or in the substrate table. SOLUTION: A lithography apparatus comprises the substrate table WT which is formed for holding a substrate W and retains the regulating fluid and a regulation system 100 for regulating the substrate table. The regulation system 100 comprises a pressure damper 104 which is communicated with the regulation system 100 through fluid and controls pressure change of the system 100.

Abstract:
PROBLEM TO BE SOLVED: To provide lithography equipment and a device manufacturing method. SOLUTION: Lithography equipment has a substrate support formed such that it supports a substrate, and a projection system formed such that it projects a patterned radiation beam to a target part of the substrate. The substrate support is operated such that the substrate is moved along a specified path of the target part as the next target of the substrate. The substrate support has a duct fabric for thermally stabilizing the substrate. This duct fabric supplies a thermal stabilization medium to the substrate through the duct, and removes the thermal stabilization medium virtually using the duct from a portion of the substrate support that supports the target part via the substrate support part that supports the target part preceding the substrate, thereby maintaining the target part as a next target thermally stably.

Abstract:
PROBLEM TO BE SOLVED: To provide an upgraded system as well as a method that discharges a mixture of liquid and gas from a component of lithography equipment. SOLUTION: This is lithography equipment including a liquid supply system for immersing, in liquid, a space between a projection system and a substrate, an outlet for eliminating a mixture of liquid and and gas that passes a gap between a liquid sealing structure of the liquid supply system and the substrate, and a discharge system for taking out the mixture through the outlet, wherein the discharge system includes a separator tank for separating the liquid from the gas in the mixture, and a separator tank pressure controller connected to a non-liquid immersion area of the separator tank and maintaining stable pressure in the non-liquid immersion area.

Abstract:
PROBLEM TO BE SOLVED: To provide an improved system and method for evacuating a mixture of liquid and gas from components in a lithographic apparatus. SOLUTION: The lithographic apparatus includes a liquid supply system configured to fill a space between a projection system and a substrate with a liquid, an outlet configured to remove a mixture of liquid and gas passing through a gap between a liquid confinement structure of the liquid supply system and the substrate, and an evacuation system configured to draw the mixture through the outlet, wherein the evacuation system has a separator tank arranged to separate liquid from gas in the mixture and a separator tank pressure controller, connected to a non-liquid-filled region of the separator tank, configured to maintain stable pressure within the non-liquid-filled region.

Abstract:
PROBLEM TO BE SOLVED: To provide a device provided with a support table for supporting a substrate. SOLUTION: The support table WT includes a plurality of support protrusions 2 that contact the substrate W when used to support the substrate W, and includes a plurality of heat transmission protrusions 3 that never contact the substrate W and are extended towards the substrate W when the substrate W is supported by the protrusions 2 in use. A heat exchange gap containing gas for exchanging the heat with the substrate W is extended between the protrusions 3 and the substrate W. COPYRIGHT: (C)2006,JPO&NCIPI
