Abstract
A method for producing a capping layer () composed of silicon oxide SiOon a coating () of a mirror (), the coating reflecting EUV radiation () e.g. for use in an EUV lithography apparatus or in an EUV mask metrology system. The method includes irradiating a capping layer () composed of silicon nitride SiNor composed of silicon oxynitride SiNOfor converting the silicon nitride SiNor the silicon oxynitride SiNOof the capping layer () into silicon oxide SiO. An associated mirror () includes a capping layer comprised of silicon oxide SiO, and can be provided in an associated EUV lithography apparatus.
