1. A lithographic apparatus, comprising:
- a substrate table configured to hold a substrate;
a projection system arranged to project a patterned beam of radiation onto a target portion of the substrate;
a liquid supply system member configured to contain a liquid in a space between the projection system and the substrate; and
a liquid supply system member compensator configured to apply a force to the liquid supply system member to at least partially compensate for an interaction between the liquid supply system member and the substrate table and coupled to a frame that is substantially mechanically isolated from the projection system, the isolated frame capable of supporting at least part of a reaction to a force applied by the liquid supply system member compensator to the liquid supply system member.

Abstract
An immersion lithographic apparatus includes a liquid supply system member configured to contain a liquid in a space between a projection system of the lithographic apparatus and the substrate and a liquid supply system member compensator arranged to compensate an interaction between the liquid supply system member and substrate table.

10. A lithographic apparatus, comprising:
-
a substrate table configured to hold a substrate; a projection system arranged to project a patterned beam of radiation onto a target portion of the substrate; a liquid supply system member configured to contain a liquid in a space between the projection system and the substrate; and a liquid supply system member compensator configured to compensate for a disturbance caused to the substrate table by a force exerted by the liquid supply system member toward the substrate table by applying a force to the liquid supply system member, wherein the liquid supply system member compensator comprises a liquid supply system member compensation device configured to apply a force to the liquid supply system member to at least partially compensate for the force exerted by the liquid supply system member toward the substrate table and coupled to a frame that is substantially mechanically isolated from the projection system, the isolated frame capable of supporting via the coupling at least part of the reaction to the force applied by the liquid supply system member compensation device to the liquid supply system member. - View Dependent Claims (11, 12)

13. A device manufacturing method, comprising:
-
containing a liquid in a space between a projection system of a lithographic apparatus and a substrate table using a liquid supply system member; compensating for an interaction between the liquid supply system member and the substrate table by using a liquid supply system member compensator coupled to a frame that is substantially mechanically isolated from the projection system; and projecting a patterned radiation beam through the liquid onto a target portion of the substrate using the projection system. - View Dependent Claims (14, 15, 16, 17, 18, 19)
