    Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for facilitating measures for any problem that contamination or damage is generated in a projection lens or its peripheral region due to gas emission of volatile components in resist during radiation exposure. SOLUTION: This lithography system projects a patterned radiation beam on the target of a substrate containing a radiation photosensitive layer by a radiation source, a patterning structure and a projection system is provided with a gas flashing system for supplying air from a region between the projection system and the substrate in order to remove gas spread from the target section while the target section is exposed by the patterned radiation beam.

    Abstract: PROBLEM TO BE SOLVED: To provide a substrate carrier which copes with various shapes and sizes of a substrate. SOLUTION: A substrate carrier WC arranged to hold a substrate in a predetermined position is disclosed. The substrate carrier has a transparent region 2 that extends through the substrate carrier from the side of the substrate carrier on which the substrate is held to the opposite side of the substrate carrier, the transparent region is formed of glass, and substantially transparent to a signal used to determine a position of an edge of the substrate on the substrate carrier.

    Abstract: A plurality of markers are printed in resist on a substrate at a range of angles relative to a crystal axis of the substrate. The markers are etched in to the substrate using an anisotropic etch process, the markers being such that after the etch their apparent positions are dependent on their orientation relative to the crystal axis. The apparent positions of the markers are measured and from this the orientation of the crystal axis is derived.
