    • Contaminants may build up on surfaces of an immersion lithographic apparatus that come into contact with an immersion liquid from during exposure of a substrate. A solution containing a cleaning agent may be used to clean such surfaces. The cleaning properties of such a cleaning solution may be improved by activating it with ultraviolet radiation. This means that a solution of a lower concentration may be used, thereby reducing the risk of damaging the surfaces to which the cleaning solution is provided. An embodiment of the present invention allows ultraviolet radiation to be provided to surfaces being cleaned without having to take the apparatus off-line. In an embodiment, a guide member is used to transfer ultraviolet radiation from a remote radiation source to an outlet located at a position where it is desired for a cleaning operation.
    • 污染物可能积聚在浸没式光刻设备的表面上,浸没式光刻设备在曝光基板期间与浸没液接触。 可以使用含有清洁剂的溶液来清洁这些表面。 这种清洗液的清洗性能可以通过用紫外线辐射激活来提高。 这意味着可以使用较低浓度的溶液,从而降低损坏提供清洁溶液的表面的风险。 本发明的实施例允许将紫外线辐射提供给被清洁的表面,而不必将设备离线。 在一个实施例中,引导构件用于将来自远程辐射源的紫外线辐射传送到位于需要进行清洁操作的位置处的出口。
