    摘要: A mirror (1) for a microlithography projection exposure apparatus including a substrate (3) and a reflective coating (5). A functional coating (11) between the substrate (3) and the reflective coating (5) has a local form variation (19) for correcting the surface form of the mirror (1), wherein the local form variation (19) is brought about by a local variation in the chemical composition of the functional coating (11) and wherein a thickness of the reflective coating (5) is not changed by the local variation in the chemical composition of the functional coating (11). The local variation in the chemical composition of the functional coating (11) can be brought about by bombardment with particles (15), for example with hydrogen ions.

    摘要: A method for preventing contaminating gaseous substances (18) from passing through an opening (17b) in a housing (4a) of an EUV lithography apparatus (1), wherein at least one optical element for guiding EUV radiation (6) is arranged in the housing (4a). The method involves: generating at least one gas flow (21a, 21b) which deflects the contaminating substances (18, 18′), and in particular is directed counter to the flow direction (Z) thereof, in the region of the opening (17b). The gas flow (21a, 21b) and the EUV radiation (6) are generated in pulsed fashion and the pulse rate of the gas flow (21a, 21b) is defined in a manner dependent on the pulse rate of the contaminating substances (18, 18′) released under the action of the pulsed EUV radiation (6), wherein both pulse rates are preferably equal in magnitude, and wherein, in the region of the opening (17b), the gas pulses temporally overlap the pulses of the contaminating substances (18, 18′). An associated EUV lithography apparatus at which the method can be carried out is also disclosed.

    摘要: In EUV lithography apparatuses (10), it is proposed, in order to lengthen the lifetime of contamination-sensitive components, to arrange them in a protection module. The protection module comprises a housing (23-29) having at least one opening (37-47), in which at least one component (13a, 13b, 15, 16, 18, 19) is arranged and at which one or more gas feeds (30-36) are provided in order to introduce a gas flow into the housing (23-29), which emerges through the at least one opening (37-47). In order to effectively prevent contaminating substances from penetrating into the protection module, a light source (48-56) is arranged at the at least one opening (37-47), which light source illuminates the opening (37-47) with one or more wavelengths by which the contaminating substances can be dissociated before they penetrate through the opening (37-47).
