    • An optical element according to an embodiment comprises a substratum for support; multilayer film (30) capable of reflecting extreme ultraviolet rays, supported by the substratum; and alloy layer (20) interposed between the multilayer film and the substratum, wherein the alloy layer (20) is a thin film of alloy. The alloy layer (20) has a tensile internal stress, reducing the compressive internal stress of the multilayer film (30). Consequently, any deformation of optical element (100) can be inhibited, thereby realizing desirable optical characteristics. Further, on the alloy layer (20), the surface roughness can be minimized. Accordingly, in the forming of the multilayer film (30) on the alloy layer (20), any disordering of the structure of the multilayer film (30) can be suppressed and any deterioration of optical characteristics can be prevented. Thus, the resolving power of exposure unit (400) can be maintained. Further, the life duration of optical element (100) eventually exposure unit (400) can be prolonged.

    • A method of manufacturing a projection objective including the steps of defining an initial design for a projection objective and optimizing the design using a merit function having a plurality of merit function components AB, IRRAD EFP, each of which reflects a particular quality parameter. One of that merit function components defines a maximum irradiance requirement requiring that a normalized effective irradiance value representing an effective irradiance AB, IRRAD EFF normalized to an effective irradiance in an image surface of the projection objective does not exceed a predefined irradiance threshold value IRR TV on each optical surface of the projection objective except for a last optical surface directly adjacent to an image surface of the projective objective. Optical surfaces positioned within caustic regions and/or critically small effective sub-apertures on optical surfaces are thereby systematically avoided.
