    • PURPOSE: To optimize a replacing quantity maintenance of the atmosphere and gas which does not absorb X ray easily by controlling the gas supply quantity with the signal through detecting the atmospheric component to be filled in a low attenuation chamber.
      CONSTITUTION: An X ray 2 from an X ray source 1 stored in a vacuum chamber 12 goes to a low attenuation chamber 5 through a shutter 3 and a beryllium window 4. After it passes through the gas which absorbs a little X ray replaced with the atmosphere here and filled, illuminates a mask 9 absorbed by the vacuum 8 on a mask chuck 7 and permeates, and passes through a gap 10 between the mask 9 and a wafer 11, a pattern on the mask 9 is transferred onto a resist of the wafer 11. An oxygen detecting sensor 13 for a detecting method is set in the abatement chamber 5 close to the mask chuck 7, and oxy gen quantity mixing into He in the abatement chamber 5 is detected. After the He quantity in the low attenuation chamber 5 are detected by the substituted oxygen quantity with a controlling method, the He quantity is controlled within the range of the proper value by a controller 14. Therefore, the X ray exposure is stabilized, production yield is improved and the X ray permeability is easily controlled.
