  • Publication number: 20090197211
    Abstract: Liquid is supplied to a space between the projection system of a lithographic apparatus and a substrate. A flow of gas towards a vacuum inlet prevents the humid gas from escaping to other parts of the lithographic apparatus. This may help to protect intricate parts of the lithographic apparatus from being damaged by the presence of humid gas.

  • Publication number: 20090184270
    Abstract: A map of the surface of a substrate is generated at a measurement station. The substrate is then moved to where a space between a projection lens and the substrate is filled with a liquid. The substrate is then aligned using, for example, a transmission image sensor and, using the previous mapping, the substrate can be accurately exposed. Thus the mapping does not take place in a liquid environment.
