| 20080218717 | Lithographic apparatus and device manufacturing method - In a lithographic apparatus, a localized area of the substrate surface under a projection system is immersed in liquid. The height of a liquid supply system above the surface of the substrate can be varied using actuators. A control system uses feedforward or feedback control with input of the surface height of the substrate to maintain the liquid supply system at a predetermined height above the surface of the substrate. | 09-11-2008 |
| 20080278696 | Lithographic apparatus - Liquid is supplied to a space between the projection system and the substrate by an inlet. In an embodiment, an overflow region removes liquid above a given level. The overflow region may be arranged above the inlet and thus the liquid may be constantly refreshed and the pressure in the liquid may remain substantially constant. | 11-13-2008 |
