Abstract:
In order to prevent delamination of a reflective coating from the substrate under the influence of reactive hydrogen, a reflective optical element ( 50 ) for EUV lithography is provided, which has a substrate ( 51 ) and a reflective coating ( 54 ) for reflecting radiation in the wavelength range of 5 nm to 20 nm. A functional layer ( 60 ) is arranged between the reflective coating ( 54 ) and the substrate ( 51 ). With the functional layer, the concentration of hydrogen in atom % at the side of the substrate facing the reflective coating is reduced by at least a factor of 2.

Claim (Index 10):
The reflective optical element as claimed in  claim 1 , wherein the reflective coating is configured as a multilayer system comprising alternately arranged layers of a material having a lower real part of the refractive index at an operating wavelength in the wavelength range of between 5 nm and 20 nm and of a material having a higher real part of the refractive index at an operating wavelength in the wavelength range of between 5 nm and 20 nm.
