Abstract:
PROBLEM TO BE SOLVED: To disclose a lithography projector in which a space between the final element of a projection system and a substrate is filled with liquid. SOLUTION: Hermetic edge sealing members 17 and 117 surround a substrate W on a substrate table WT or another object at least partially thus preventing the catastrophic loss of the liquid when the edge part of the substrate is imaged or illuminated.

Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic projection apparatus in which a space between the substrate and projection system is filled with a liquid while minimizing the volume of the liquid that must be accelerated during stage movements. SOLUTION: In the lithographic projection apparatus, a seal member surrounds a space between the final element of the projection system and a substrate table of the lithographic projection apparatus. A gas seal is formed between the seal member and the surface of the substrate to contain the liquid in the space. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a lithography projection apparatus in which space between a substrate and a projection system is filled with liquid while minimizing the quantity of the liquid required to be accelerated during a stage operation. SOLUTION: In the lithography projection apparatus, space between a final element of the projection system and a substrate table of the lithography projection apparatus is surrounded by a sealing member. A gas seal is formed between the sealing member and a plane of the substrate and the liquid is confined in the space. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic projection apparatus which minimizes a liquid loss from a supply system during the exposure of ends of a substrate, in liquid immersion exposure. SOLUTION: Liquid is limited by a middle plate 210 located between the liquid supply system and the substrate W. Spaces 222, 215 among the middle plate 210, a transmitted image sensor (TIS) 220, and the substrate W are also filled with the liquid 111. This procedure can be performed by two separated space liquid-supply systems via holes 230, 240, or can be performed by the same space liquid-supply system via the holes 230, 240. Therefore, both the space 215 between the substrate W and the middle plate 210, and the space 225 between the transmitted image sensor 220 and the middle plate 210 are filled with the liquid, so that both the substrate W and the transmitted image sensor can be illuminated under the same condition. A part 200 provides one or a plurality of support surfaces with the middle plate 210 which can be held at a predetermined position by a vacuum source. COPYRIGHT: (C)2007,JPO&INPIT
