Abstract:
A lithographic apparatus is disclosed that includes a projection system, and a liquid confinement structure configured to at least partly confine immersion liquid to an immersion space defined by the projection system, the liquid confinement structure and a substrate and/or substrate table. Measures are taken in the lithographic apparatus, for example, to reduce the effect of droplets on the final element of the projection system or to substantially avoid such droplet formation.

Claim (Index 21):
An immersion lithographic apparatus comprising:\n a projection system configured to project a patterned radiation beam through an optically active part of a final optical element of the projection system towards a substrate supported by a substrate table; a liquid confinement structure configured to supply and at least partly confine immersion liquid to an immersion space between the final optical element of the projection system and a surface of the substrate and/or the substrate table; and a passageway-forming member between the projection system and the liquid confinement structure, and a passageway between the passageway-forming member and the optically active part of the final optical element, the passageway having an end nearest to a bottom surface of the final optical element and an opening into the passageway away from the end to allow liquid into the passageway.
