    Abstract: A glass article for use in Extreme Ultra-Violet Lithography (EUVL) is provided. The glass article includes a silica-titania glass having a compositional gradient through the glass article, the compositional gradient being defined by the functions: [TiO2]=(c+f(x,y,z)), and [SiO2]=(100−{c+f(x,y,z)}−δ(x,y,z)) wherein [TiO2] is the concentration of titania in wt. %, [SiO2] is the concentration of silica in wt. %, c is the titania concentration in wt. % for a predetermined zero crossover temperature (Tzc), f(x, y, z) is a function in three-dimensional space that defines the difference in average composition of a volume element centered at the coordinates (x, y, z) with respect to c, and δ(x, y, z) is a function in three-dimensional space that defines the sum of all other components of a volume element centered at the coordinates (x, y, z).

    Abstract: On the basis of a known method for producing a blank of titanium-doped glass with a high silica content (glass) for a mirror substrate for use in EUV lithography which has a surface region that has an outer contour, is intended to be provided with a reflective coating and is specified as a highly loaded zone when the mirror substrate is used as intended, in order to provide a blank which can be produced at low cost and nevertheless meets high requirements with respect to homogeneity and freedom from blisters and striae, a procedure which comprises the following method steps is proposed: (a) producing a front body of titanium-doped high-quality glass with dimensions more than large enough to enclose the outer contour, (b) producing a cylindrical supporting body from titanium-doped glass, (c) bonding the front body and the supporting body to form a composite body, and (d) working the composite body to form the mirror substrate blank, wherein the step of producing the front body comprises a homogenizing process involving twisting a starting body obtained in the form of a strand by flame hydrolysis of a silicon-containing compound to form a front body blank, and the supporting body is formed as a monolithic glass block with less homogeneity than the front body.

    Abstract: The invention relates to an optical filter material made of doped quartz glass, which at a low dopant concentration exhibits spectral transmission as high as possible of at least 80% cm−1 for operating radiation of 254 nm, transmission as low as possible in the wave range below approximately 250 nm, and an edge wavelength λc within the wave range of 230 to 250 nm. It was found that this aim is achieved by doping comprising a gallium compound, which in the wave range below 250 nm has a maximum of an absorption band and thus determines the edge wave range λc.
