    • PROBLEM TO BE SOLVED: To provide a method and an apparatus for removing debris from a reflecting surface of an EUV (Extreme ultraviolet) collector in an EUV light source. SOLUTION: A current source (DC voltage source) 220 may be connected to a collector mirror 150, a metallic backing material (aluminum or nickel) for the mirror 150. The mirror 150 may be heated to a temperature higher than the temperature of ambient gas (helium gas) filling the inside of a chamber 26. In another aspect of debris cleaning, introduction of RF from an antenna schematically shown by an RF frequency voltage 230 and 232 in the chamber 26 may be incorporated. The RF may be connected to the mirror 150 or the metallic backing material, and in this case, a dark shield made of an appropriate conductive material and connected to the earth potential may be formed by covering the back face of the collector mirror 150, and is separated from the mirror by an insulator (air gap) and a voltage (DC from the DC power source 220 connected to the mirror 150 as well).

    • 要解决的问题:提供一种在EUV光源中从EUV(极紫外)捕集器的反射表面去除碎屑的方法和装置。 解决方案:电流源(DC电压源)220可以连接到收集器反射镜150,用于反射镜150的金属背衬材料(铝或镍)。反射镜150可以被加热到高于温度 环境气体(氦气)填充在室26的内部。在碎片清洁的另一方面,可以并入从RF 26电压230和232中示意性地示出的天线引入RF。 RF可以连接到反射镜150或金属背衬材料,并且在这种情况下,可以通过覆盖收集镜150的背面形成由适当的导电材料制成并连接到地电位的暗屏蔽, 通过绝缘体(气隙)和电压(也连接到反射镜150的直流电源220的DC)与反射镜分离。 版权所有(C)2011,JPO&INPIT
