Lithographic apparatus and device manufacturing method
First Claim
1. A device manufacturing method comprising:
- projecting, with a projection system, a patterned beam of radiation onto a target portion of a substrate held by a substrate table, said substrate table includingan edge seal member configured to at least partly surround an edge of said substrate, an object positioned on said substrate table, or both, anda hydrophobic layer adjacent an edge portion of said edge seal member and adjacent said at least one of said substrate and said object, said hydrophobic layer arranged to face an opposite side of said edge seal member to said projection system and to face an opposite side of said at least one of said substrate and said object to said projection system, andproviding a liquid, through which said patterned beam of radiation is projected, to a space between said projection system and said substrate, said object, or both.

Abstract
A lithographic projection apparatus includes a support structure to hold a patterning device, the patterning device configured to pattern a beam of radiation according to a desired pattern; a projection system to project the patterned beam onto a target portion of a substrate; a substrate table configured to hold the substrate, the substrate table including a support surface to support an intermediary plate between the projection system and at least one of the substrate and an object positioned on the substrate table and not in contact with the at least one of the substrate and the object; and a liquid supply system to provide a liquid, through which the beam is to be projected, in a space between the projection system and the at least one of the substrate and the object.

12. A device manufacturing method comprising:
-
providing a liquid, using a liquid supply system, in a space between a projection system and a substrate supported on a substrate table, the substrate table comprising an edge seal member at least partly surrounding an edge of the substrate, an object positioned on the substrate table, or both; repelling liquid entering a gap between said edge seal member and the substrate, the object or both using a hydrophobic layer adjacent an edge portion of said edge seal member and adjacent said at least one of said substrate and said object, and projecting a patterned beam, using the projection system and through the liquid, onto a target portion of the substrate supported on the substrate table. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
