    摘要: A lithographic apparatus includes a radiation source configured to produce extreme ultraviolet radiation, the radiation source including a chamber in which a plasma is generated; a collector mirror configured to reflect radiation emitted by the plasma; and a debris mitigation system including a gas supply system configured to supply a first gas flow toward the plasma, the first gas flow being selected to thermalize debris generated by the plasma, and a plurality of gas manifolds arranged at a location proximate the collector mirror, the gas manifolds configured to supply a second gas flow in the chamber, the second gas flow being directed toward the plasma to prevent thermalized debris from depositing on the collector mirror.

    摘要: A lithographic apparatus includes a source for generating radiation, an illumination system for conditioning the radiation, a patterning device for patterning the conditioned radiation, and a projection system for projecting the patterned radiation onto a target portion of a substrate. The illumination system includes a debris mitigating system for mitigating debris particles that are released with the generation of radiation, and an optical system for collecting the radiation. The debris mitigation system is arranged to directly evaporate the debris particles, or to directly charge the debris particles, or to directly produce a plasma out of the debris particles, or any combination thereof, in a path along which the radiation propagates from the source to the optical system.
