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.

Abstract: A reticle includes an area provided with a conductive metal-based compound coating for electrically grounding the reticle. The reticle is suitable for use with a lithography apparatus whereby the reticle pattern is imaged using extreme ultra violet radiation. One or more conducting pins, held at zero potential, may be pressed against the conductive coating for electrically grounding the reticle either during patterning the reticle by electron beam writing or during use in the lithographic apparatus. The areas coated with the metal-based compounds are wear resistant which reduces the occurrence of particles due to damage caused by mechanical contact between the conducting pins and the conductive coating.

Abstract: The invention relates to a box for transporting lithographic patterning device, the box being arranged to cooperate with a lithographic apparatus. The transport box is provided with a container part having an inner space with a storing position for storing the patterning device and an opening for the transfer of the patterning device. The box also comprises a closure part for closing the opening, and a channel system for evacuating and/or feeding gasses from/to the inner space the box. The invention also relates to a lithographic apparatus configured to cooperate with the transport box.
