    • A lithographic projection apparatus includes a radiation system configured to supply a beam of radiation; a mask table provided with a mask holder for holding a mask; a substrate table provided with a substrate holder for holding a substrate; a projection system configured to image an irradiated portion of the mask onto a target portion of the substrate, wherein the projection system is separated from the substrate table by an intervening space that is at least partially evacuated and is delimited at the location of the projection system by a solid surface from which the employed radiation is directed toward the substrate table; the intervening space contains a hollow tube located between the solid surface and the substrate table and situated around the path of the beam of radiation, the tube being configured such that beam of radiation focused by the projection system onto the substrate table does not intercept a wall of the hollow tube; a flushing system is configure to continually flush the inside of the hollow tube with a flow of gas, wherein the gas is hydrogen, the flow of the gas is opposed to the flow of contaminants from the substrate and/or the hollow tube is in fluid communication with the intervening space.
    • 光刻投影设备包括被配置为提供辐射束的辐射系统; 设置有用于保持面罩的面罩座的面罩台; 设置有用于保持基板的基板保持器的基板台; 投影系统,被配置为将所述掩模的照射部分成像到所述基板的目标部分上,其中所述投影系统通过至少部分抽真空并且在所述投影系统的位置处界定的中间空间与所述基板台分离 通过使用的辐射从该表面朝向衬底台的固体表面; 中间空间包含位于固体表面和基底台之间的中空管,并且位于辐射束的路径周围,该管被配置成使得由投影系统聚焦到衬底台上的辐射束不会拦截壁 的中空管; 冲洗系统被配置为以气流连续冲洗中空管的内部,其中气体是氢气,气体的流动与来自基底和/或中空管的污染物的流动相对流体 与中间空间的沟通。
