摘要: Degradation of the reflectivity of one or more reflective optical elements in a system for generating EUV radiation is reduced by the controlled introduction of a gas into a vacuum chamber containing the optical element. The gas may be added to the flow of another gas such as hydrogen or alternated with the introduction of hydrogen radicals.

摘要: A method for manufacturing a membrane assembly for EUV lithography, the method including: providing a stack including: at least one membrane layer supported by a planar substrate, wherein the planar substrate has an inner region and a border region around the inner region; and a first sacrificial layer between the planar substrate and the membrane layer; selectively removing the inner region of the planar substrate such that the membrane assembly has: a membrane formed from the at least one membrane layer, and a border holding the membrane, the border having the border region of the planar substrate and the first sacrificial layer situated between the border region and the membrane layer, wherein the selectively removing the inner region of the planar substrate includes using an etchant which has a similar etch rate for the membrane layer and its oxide and a substantially different etch rate for the first sacrificial layer.

摘要: A membrane transmissive to EUV radiation, which may be used as a pellicle or spectral filter in a lithographic apparatus. The membrane includes one or more high doped regions wherein the membrane is doped with a dopant concentration greater than 1017 cm−3, and one or more regions with low (or no) doping. The membrane may have a main substrate having low doping and one or more additional layers, wherein the high doped regions are comprised within some or all of the additional layers.

摘要: Degradation of the reflectivity of one or more reflective optical elements in a system (SO) for generating EUV radiation is reduced by the controlled introduction of a gas into a vacuum chamber (26) containing the optical element. The gas may be added to the flow of another gas such as hydrogen or alternated with the introduction of hydrogen radicals.
