    • PURPOSE: An energy efficient lithography laser is provided to precisely control of the fluorine concentration in a gas discharge laser chamber. CONSTITUTION: With valves(10, 6, 15, 12, 17, 4) closed, valves(6,12) are opened, vacuum pump(13) is operated and the laser chamber is pumped down to an absolute pressure of less than 13 kPa. (A direct pump down line may be provided between the chamber 1 and vacuum pump 13 to permit a quick pump down.) Valve(12) is closed. Valve(16) is opened and 1% Kr, 99%Ne buffer gas from buffer gas bottle(16) is added to the chamber to fill it to a pressure equivalent to 262 kPa at 50 DEG C. (Note that for this 20.3 liter laser chamber, temperature correction can be approximated using a .DELTA.P/.DELTA.T correction of 1 kPa/ DEG C. for a chamber temperature deviation from 50 DEG C. So if the chamber temperature is 23 DEG C. it would be filled to 247 kPa.) Valve(17) is closed and valve(15) is opened and a quantity of the 1% F1, 1% Kr, 98% Ne mixture from halogen rich gas bottle(14) is added to chamber(1) to fill it to a pressure equivalent to 290 kPa at 50 DEG C. (Note the same temperature correction discussed above can be used.) This will produce a gas mixture in the chamber of approximately 0.1% F1, 1.0% Kr and 98.9% Ne. When the chamber is heated to about 50 DEG C. the pressure will be about 3 atm or 290 kPa.
    • 目的:提供一种高效光刻激光器,精确控制气体放电激光室中的氟浓度。 构成:阀门(10,6,15,12,17,4)关闭,阀门(6,12)打开,真空泵(13)运行,激光室被泵送到绝对压力小于13 千帕。 (可以在室1和真空泵13之间提供直接泵送管路,以允许快速抽吸)。阀(12)关闭。 打开阀门(16),并将1%的Kr,99%的来自缓冲气瓶(16)的缓冲气体加入到室中,以在50℃下将其填充到262kPa的压力(注意,对于该20.3升 激光室,温度校正可以用1Pa /℃的±DELTA.P / .DELTA.T校正近似,以使室温偏离50℃。因此,如果室温为23℃ 填充到247kPa。)阀(17)关闭并且阀(15)打开,并且将来自富含卤素的气瓶(14)的1%F1,1%Kr,98%Ne混合物的量加入到室(1) ),在50℃下将其填充至290kPa的压力(注意,可以使用上述相同的温度校正)。这将在室内产生约0.1%的F1,1.0%的Kr和98.9%的气体混合物, 东北。 当室被加热至约50℃时,压力将为约3atm或290kPa。
