摘要： A radiation source is configured to generate extreme ultraviolet radiation. The radiation source includes a fuel supply configured to supply a fuel to a plasma formation site; a laser configured to emit a beam of radiation to the plasma formation site so that a plasma that emits extreme ultraviolet radiation is generated when the beam of radiation impacts the fuel; a fuel particulate interceptor constructed and arranged to shield at least part of the radiation source from fuel particulates that are emitted by the plasma, the fuel particulate interceptor comprising a first portion and a second portion, the second portion being positioned closer to the plasma formation site than the first portion, and the first portion being rotatable; and a fuel particulate remover constructed and arranged to remove fuel particulates from a surface of the fuel particulate interceptor and to direct the fuel particulates towards a collection location.

摘要： A module for producing extreme ultraviolet radiation includes a supply configured to supply droplets of an ignition material to a predetermined target ignition position and a laser arranged to be focused on the predetermined target ignition position and to produce a plasma by hitting such a droplet which is located at the predetermined target ignition position in order to change the droplet into an extreme ultraviolet producing plasma. Also, the module includes a collector mirror having a mirror surface constructed and arranged to reflect the radiation in order to focus the radiation on a focal point. A fluid supply is constructed and arranged to form a gas flow flowing away from the mirror surface in a direction transverse with respect to the mirror surface in order to mitigate particle debris produced by the plasma.

摘要： An EUV lithographic apparatus includes a source collector apparatus in which the extreme ultraviolet radiation is generated by exciting a fuel to provide a plasma emitting the radiation. The source collector apparatus includes a chamber in fluid communication with a guide way external to the chamber. A pump for circulating buffer gas is part of the guide way, and provides a closed loop buffer gas flow. The gas flowing through the guide way traverses a gas decomposer wherein a compound of fuel material and buffer gas material is decomposed, so that decomposed buffer gas material can be fed back into the closed loop flow path.
