摘要:
A method of forming an optical component includes fusing glass powder material to a facesheet to form a first core material layer on the facesheet. The method also includes successively fusing glass powder material in a plurality of additional core material layers to build a core material structure on the facesheet. The method can include positioning the facesheet on a mandrel prior to fusing glass powder material to the facesheet. Fusing glass powder material to the facesheet can include fusing the glass powder material to a polishable surface of the facesheet.

A method for producing a silica glass blank co-doped with titanium and fluorine for use in EUV lithography includes (a) producing a TiO2—SiO2 soot body by flame hydrolysis of silicon- and titanium-containing precursor substances, (b) fluorinating the TiO2—SiO2 soot body to form a fluorine-doped TiO2—SiO2 soot body, (c) treating the fluorine-doped TiO2—SiO2 soot body in a water vapor-containing atmosphere to form a conditioned soot body, and (d) vitrifying the conditioned soot body to form the blank. The blank has an internal transmission of at least 60% in the wavelength range of 400 to 700 nm at a sample thickness of 10 mm, a mean OH content in the range of 10 to 100 wt. ppm and a mean fluorine content in the range of 2,500 to 10,000 wt. ppm. Titanium is present in the blank in the oxidation forms Ti3+ and Ti4+.

摘要:
A porous soot sheet is formed using a roll-to-roll glass soot deposition and sintering process. The soot sheet formation involves depositing glass soot particles on a deposition surface to form a supported soot layer, removing the soot layer from the deposition surface to form a soot sheet, and heating a portion of the soot sheet to locally-sinter the glass soot particles and form a porous soot part having a sintered peripheral edge.
