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 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 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 method and apparatus for accurately aligning and/or leveling a substrate in an immersion lithography apparatus. SOLUTION: A map of the surface of a substrate is generated at a measurement station. The substrate is then moved to a place where a space between a projection lens and the substrate is filled with a liquid. The substrate is then aligned using, for example, a transmission image sensor and, using the previous mapping, the substrate can be accurately exposed. Thus the mapping does not take place in a liquid environment. COPYRIGHT: (C)2009,JPO&INPIT
