    • A lithographic apparatus includes a support constructed to support a patterning device that is capable of imparting a radiation beam with a pattern in its cross-section to form a patterned radiation beam, a substrate table constructed to hold a substrate, a projection system configured to project the patterned radiation beam onto a target portion of the substrate, an interior space through which an interferometer beam propagates, and a first gas supply for supplying a purge gas to inhibit contamination of the projection system. The purge gas has a predetermined refractive index. The apparatus also includes a second gas supply for supplying a conditioning gas to the interior space for conditioning the interior space, and a refractive index matching system arranged to match the refractive index of the conditioning gas to the predetermined refractive index of the purge gas.
    • 光刻设备包括:支撑构件,用于支撑图案形成装置,该构图装置能够在其横截面中赋予具有图案的辐射束以形成图案化的辐射束;构造成保持衬底的衬底台;被配置为投影 图案化的辐射束到基板的目标部分,干涉仪光束传播的内部空间以及用于供应吹扫气体以抑制投影系统的污染的第一气体供应。 净化气体具有预定的折射率。 该设备还包括用于将调节气体供应到内部空间用于调节内部空间的第二气体供应源,以及折射率匹配系统,其布置成使调节气体的折射率与净化气体的预定折射率相匹配。
