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 vacuum port, or a liquid supply port, or both, positioned to provide respectively vacuum or liquid to a gap between said edge seal member and said substrate, said object, or both, on a side opposite 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.

14. 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 including an edge seal member configured to at least partly surround an edge of the substrate, an object, or both, positioned on said substrate table and to provide a primary surface facing said projection system substantially co-planar with a primary surface of said substrate, said object, or both, and providing 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, and to a localized area of (i) said object, (ii) said edge seal member, (iii) said substrate, or (iv) any combination of (i) (iii). - View Dependent Claims (15, 16, 17, 18, 19, 20)
