abstract = {Lithography and patterning on a nanometre scale with
extreme ultraviolet (EUV) and soft X-ray radiation allow
creation of high resolution, high density patterns
independent of a substrate type. To realize the full
potential of this method, especially for EUV proximity
printing and interference lithography, a reliable technology
for manufacturing of the transmission masks and gratings
should be available. In this paper we present a development
of broadband amplitude transmission masks and gratings for
extreme ultraviolet and soft X-ray lithography based on
free-standing niobium membranes. In comparison with a
standard silicon nitride based technology the transmission
masks demonstrate high contrast not only for in-band EUV
(13.5 nm) radiation but also for wavelengths below Si
L-absorption edge (12.4 nm).The masks and filters with free
standing areas up to 1000 x 1000 mu m(2) and 100 nm to 300
nm membrane thicknesses are shown. Electron beam structuring
of an absorber layer with dense line and dot patterns with
sub-50 nm structures is demonstrated. Diffractive and
filtering properties of obtained structures are examined
with EUV radiation from a gas discharge plasma source. (C)
