    摘要: A cleaning module for an EUV lithography device with a supply (206) for molecular hydrogen, a heating filament (210) and a line (212) for atomic and/or molecular hydrogen. The line (212) has at least one bend with a bending angle of less than 120 degrees, and has a material on its inner surface which has a low recombination rate for atomic hydrogen. The supply (206) is of flared shape at its end, which faces the heating filament (210). A gentler cleaning of optical elements is achieved with such a cleaning module, or also by exciting a cleaning gas with a cold cathode or a plasma, or by filtering out charged particles via of electrical and/or magnetic fields.
