  • EUV MIRROR, INSPECTION SYSTEM, MASK INSPECTION APPARATUS, METHOD FOR EXAMINING AN EUV MIRROR
    Publication number: 20260219588
    Abstract: The invention relates to an EUV mirror comprising a mirror body and a holding component, wherein the holding component is connected to the mirror body by way of an adhesive bond and wherein an optical surface with high reflectivity for EUV radiation is formed on the mirror body. The mirror body consists of a transparent material. The surface of the mirror body comprises a non-transparent surface region and a viewing window. The viewing window provides an observation channel to the adhesive bond. The invention also relates to an inspection system, a mask inspection apparatus and a method for examining an EUV mirror.
