Abstract:
PROBLEM TO BE SOLVED: To increase lyophobic properties of an immersion lithography apparatus surface. SOLUTION: The immersion lithography apparatus has a surface contacted by an immersion liquid when used, and the surface has a surface roughness of 0.2 μm or less. The immersion liquid on the surface may have a contact angle of 60 degrees or higher. The surface may maintain the characteristic so that the immersion liquid has the contact angle enabling the immersion for a long period of time. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To disclose a lithographic projection apparatus that includes a table, a shutter member, a fluid handling structure, and a fluid extraction system. SOLUTION: The fluid handling structure may be configured to supply and confine liquid between a projection system and (i) a substrate, or (ii) the substrate table, or (iii) a surface of the shutter member, or (iv) an arbitrary combination selected from (i)-(iii). The surface of the shutter member may adjoin and be co-planar with a surface of the table. The surfaces of the shutter member and the table may be spaced apart by a gap. The fluid extraction system may be configured to remove liquid from the gap. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To disclose a lithographic projection apparatus comprising a table, a shutter member, fluid handling structure, and a fluid extraction system.SOLUTION: Fluid handling structure supplies and shuts in liquid between a projection system and (i) a substrate, (ii) a substrate table, (iii) a surface of a shutter member, or (iv) an arbitrary combination selected from (i)-(iii). The surface of the shutter member adjoins a surface of the table and is disposed on the same surface of the table. The surface of the shutter member and the surface of the table can be separated by gap. A fluid extraction system removes the liquid from the gap.
