More Information
Summary:An optical arrangement for EUV lithography, including: at least one component (23) having a main body (32) with at least one surface region (30) which is exposed to activated hydrogen (H+, H*) during operation of the optical arrangement. The main body (32) contains at least one material which forms at least one volatile hydride upon contact of the surface region (30) with the activated hydrogen (H+, H*). At the surface region, noble metal ions (38) are implanted into the main body (32) in order to prevent the formation of the volatile hydride.
