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 9):
The reflective optical element as claimed in  claim 1 , further comprising an adhesion promoter layer arranged on the substrate, wherein the adhesion promoter layer comprises at least one ply and comprises at least one of: ruthenium, chromium, platinum, iridium, copper, silver, gold, nickel, nickel-phosphorus, tantalum, titanium, zirconium, tungsten, molybdenum and niobium.
