    摘要: A lithographic apparatus including a filter device is disclosed. The filter device has a plurality of foils attached to a holder which is able to rotate around a rotation axis. The foils are arranged substantially parallel to the rotation axis. The foils comprise a uni-directional carbon-fiber composite material selected from the group consisting of carbon-carbon composite (C-C composite) and carbon-silicon carbide composite (C—SiC composite). During operation, the filter device rotates and filters out debris from a radiation source, such as a Sn plasma source. Such a filter device per se may be provided.
