    • A lithographic apparatus includes a radiation system that provides a beam of radiation, and a support structure that supports a patterning structure. The patterning structure is configured to pattern the beam of radiation according to a desired pattern. The apparatus also includes a substrate support that supports a substrate, and a projection system that projects the patterned beam onto a target portion of the substrate. The projection system includes an optical element that has a beam exit area through each of which the patterned beam passes. The apparatus further includes a fluid cleaning system that cleans a fluid to be introduced into a region in between the optical element and the substrate. The fluid cleaning system includes a fluid inlet, a fluid outlet, and a cleaning zone disposed between the inlet and outlet. The cleaning zone includes a nucleated surface provided with a plurality of nucleation sites.
    • 光刻设备包括提供辐射束的辐射系统和支撑图案化结构的支撑结构。 图形结构被配置为根据期望的图案对辐射束进行图案化。 该装置还包括支撑基板的基板支撑件和将图案化的光束投影到基板的目标部分上的投影系统。 投影系统包括光学元件,该光学元件具有通过图案化光束通过的每一个的光束出射区域。 该装置还包括清洁被引入到光学元件和基板之间的区域中的流体的流体清洁系统。 流体清洁系统包括流体入口,流体出口和布置在入口和出口之间的清洁区域。 清洁区包括具有多个成核位点的成核表面。
