    Abstract: A reflector includes a multi layer mirror structure configured to reflect radiation at a first wavelength, and one or more additional layers. The absorbance and refractive index at a second wavelength of the multi layer mirror structure and the one or more additional layers, and the thickness of the multi layer mirror structure and the one or more additional layers, are configured such that radiation of the second wavelength which is reflected from a surface of the reflector interferes in a destructive manner with radiation of the second wavelength which is reflected from within the reflector.

    Abstract: A multilayer mirror (100) is configured to reflect extreme ultraviolet (EUV) radiation while absorbing a second radiation having a wavelength substantially- longer than that of the EUV radiation. The mirror includes a plurality of layer pairs (110, 112) stacked on a substrate (104). Each layer pair comprises a first layer (112) that includes a first material, and a second layer (110) that includes a second material. The first layer (112) is modified to reduce its contribution to reflection of the second radiation, compared with a simple layer of the same metal having the same thickness. Modifications can include doping with a third material in or around the metal layer to reduce its electric conductivity by chemical bonding or electron trapping, and/or splitting the metal layer into sub-layers with insulating layers. The number of layers in the stack is larger than known multilayer mirrors and may be tuned to achieve a minimum in IR reflection.

    Abstract translation: 多层反射镜（100）被配置为反射极紫外（EUV）辐射，同时吸收具有比EUV辐射的波长更大的波长的第二辐射。 反射镜包括堆叠在基板（104）上的多个层对（110,112）。 每层对包括包括第一材料的第一层（112）和包括第二材料的第二层（110）。 与具有相同厚度的相同金属的简单层相比，第一层（112）被修改以减少其对第二辐射的反射的贡献。 修改可以包括在金属层中或其周围掺杂第三材料，以通过化学键合或电子俘获来降低其导电性，和/或将金属层分成具有绝缘层的子层。 堆叠中的层数大于已知的多层反射镜，并且可以调谐以在IR反射中达到最小。

    Abstract: A radiation source (60) suitable for providing a beam of radiation to an illuminator of a lithographic apparatus. The radiation source comprises a nozzle configured to direct a stream of fuel droplets (62) along a trajectory (64) towards a plasma formation location (66). The radiation source is configured to receive a first amount of radiation (68) such that the first amount of radiation is incident on a fuel droplet (62a) at the plasma formation location, and such that the first amount of radiation transfers energy into the fuel droplet to generate a modified fuel distribution (70), the modified fuel distribution having a surface. The radiation source is also configured to receive a second amount of radiation (72) such that the second amount of radiation is incident on a portion of the surface (70a) of the modified fuel distribution, the second amount of radiation having a p-polarized component with respect to the portion of the surface; and such that the second amount of radiation transfers energy to the modified fuel distribution to generate a radiation generating plasma, the radiation generating plasma emitting a third amount of radiation (74). The radiation source further comprises a collector (CO) configured to collect and direct at least a portion of the third amount of radiation. The radiation source is configured such that the second amount of radiation propagates in a first direction, the first direction being non-parallel to a normal to the portion of the surface of the modified fuel distribution.
