Abstract:
Treating a reflective optical element ( 104 ) for the EUV wavelength range that has a reflective coating on a substrate. The reflective optical element in a holder ( 106 ) is irradiated with at least one radiation pulse of a radiation source ( 102 ) having a duration of between 1 μs and 1 s. At least one radiation source ( 102 ) and the reflective optical element move relative to one another. Preferably, this is carried out directly after applying the reflective coating in a coating chamber ( 100 ). Reflective optical elements of this type are suitable in particular for use in EUV lithography or in EUV inspection of masks or wafers, for example.

Claim (Index 1):
A method for treating a reflective optical element for the EUV wavelength range comprising a reflective coating on a substrate, comprising:\n irradiating the reflective optical element with at least one radiation pulse having a duration of between 1 \u03bcs and 1 s, wherein the irradiating is carried out with at least one radiation source, and moving the at least one radiation source and the reflective optical element with respect to one another.
