Patent ID: 7652746

Claim:
A lithographic apparatus configured to project a patterned radiation beam onto a target portion of a substrate held on a substrate holder of a substrate table, comprising: a liquid supply system configured to at least partly fill a space between a projection system and the substrate table with liquid; a liquid confinement structure arranged to at least partially contain the liquid within the space; a substrate table displacement system arranged to move the substrate table along a path relative to the liquid confinement structure, thereby to move the target portion over the surface of the substrate; a timetable comprising positions and timings of the substrate displacement system at which the substrate is likely to be undergoing localized cooling; and a liquid evaporation or condensation controller arranged to control the net rate of energy lost through evaporation or condensation of liquid supplied by the liquid supply system by synchronizing evaporation or condensation controlling techniques with the timetable.
