Patent ID: 8456611

Claim:
A lithography system, comprising: a substrate table configured to support a substrate; a projection system to project a patterned beam of radiation onto a target portion of the substrate; and a liquid supply system to at least partially fill a space between the projection system and the substrate and/or the substrate table with an immersion liquid, the liquid supply system comprising a liquid confinement structure that extends along at least a part of a boundary of the space between the projection system and the substrate table and/or substrate, wherein the liquid confinement structure comprises a glass-ceramic and comprises a material to provide a contact angle of between about 90 degrees and 140 degrees with the liquid, wherein the material to provide the contact angle of between about 90 degrees and 140 degrees with the liquid is adjacent or located away from an inlet or outlet of the liquid supply system and is, in use, in contact with liquid supplied to the space from the inlet before removal by the outlet.
