    Abstract: A radiation source is configured to generate extreme ultraviolet radiation. The radiation source includes a plasma formation site located at a position in which a fuel is contacted by a beam of radiation to form a plasma, a collector constructed and arranged to collect extreme ultraviolet radiation formed at the plasma formation site and form an extreme ultraviolet radiation beam, and a contamination barrier. The contamination barrier includes a plurality of foils at least partially located between the plasma formation site and the collector, and a rotatable base operatively connected to the plurality of foils. The rotatable base is configured to allow the beam of radiation to pass through the contamination barrier to the plasma formation site.

    Abstract: A debris prevention system is constructed and arranged to prevent debris that emanates from a radiation source from propagating with radiation from the radiation source into or within a lithographic apparatus. The debris prevention system includes an aperture that defines a maximum emission angle of the radiation coming from the radiation source, and a first debris barrier having a radiation transmittance. The first debris barrier includes a rotatable foil trap. The debris prevention system also includes a second debris barrier that has a radiation transmittance. The first debris barrier is configured to cover a part of the emission angle and the second debris barrier is configured to cover another part of the emission angle.

    Abstract: A debris mitigation system for trapping contaminant material coming from a debris-generating radiation source. The system includes a contamination barrier constructed and arranged to rotate about an axis, and a magnet structure constructed and arranged to provide a magnetic field for deflecting charged debris from the radiation source. The magnet structure is constructed and arranged to provide a magnetic field through the contamination barrier. The magnetic field, when passing through the contamination barrier, is oriented along planes generally coinciding with the axis of rotation of the contamination barrier.

    Abstract: A patterning device for a photolithographic apparatus is used to form a patterned radiation beam, by imparting a cross-sectional pattern to the radiation beam during reflection from the patterning device. The patterning device comprises a layer of phase-change material that is capable of locally undergoing an induced structural phase change into respective ones of a plurality of stable and/or metastable states. Furthermore, the patterning device comprises a radiation reflective structure with periodically arranged layers adjacent to the layer of phase-change material. The radiation reflective structures do not partake in the phase changes. By locally changing the phase of the phase-change material, the reflectivity of the whole structure is modified, for example due to thickness changes in the layer of phase-change material that lead to destructive interference of different components of the reflected light or due to changes in surface roughness of the radiation reflective structure.
