The invention is directed to an arrangement for generating EUV radiation particularly for source modules in exposure installations for EUV lithography for semiconductor chip fabrication. The object of the invention, to find a novel possibility for realizing an EUV source module which appreciably improves the ratio of resources to results in the transfer of radiation from the primary source location (plasma 3) to the secondary source location (output opening (6) of the source module (1)/intermediate focus plane (62)), is met according to the invention in that the plasma (3) is formed as a volume emitter for direct illumination of the output opening (6) without collector optics (5), and the transverse dimension (d) of the plasma (3) is greater than the diameter (D) of the output opening (6), wherein the extent to which the diameter is exceeded depends on the distance (L) between the plasma (3) and the output opening (6) and on the numerical aperture (NA) of the illumination system downstream. |
