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 28):
An immersion lithographic apparatus comprising:\n a projection system configured to project a patterned radiation beam through an optically active bottom surface of a final optical element of the projection system and towards a substrate supported by a substrate table; a liquid confinement member 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; a structure located between the liquid confinement structure and the projection system, the structure configured to define a passageway between structure and the projection system; and a liquid supply opening outward of the optically active bottom surface of the final optical element adapted to provide a flow of a liquid through the passageway and over a lower surface of the final optical element towards the optically active bottom surface of the final optical element.
