    摘要: High purity silicon oxyfluoride glass suitable for use as a photomask substrates for photolithography applications in the VUV wavelength region below 190 nm is disclosed. The inventive silicon oxyfluoride glass is transmissive at wavelengths around 157 nm, making it particularly useful as a photomask substrate at the 157 nm wavelength region. The inventive photomask substrate is a “dry,” silicon oxyfluoride glass which exhibits very high transmittance in the vacuum ultraviolet (VUV) wavelength region while maintaining the excellent thermal and physical properties generally associated with high purity fused silica. In addition to containing fluorine and having little or no OH content, the inventive silicon oxyfluoride glass suitable for use as a photomask substrate at 157 nm is also characterized by having less than 1×1017 molecules/cm3 of molecular hydrogen and low chlorine levels.

    摘要: An apparatus for producing a glass soot includes a first a burner having a droplet-emitting first region, a gas-emitting second region surrounding the first region, and a gas-emitting third region surrounding the second region. The first region emits a glass-forming mixture, the second region emits an inert gas, and the third region emits a combination of oxygen and a combustible gas. The apparatus further includes a combustion area having a first section proximate the first burner and a second section distal from the first burner. A glass-forming mixture is at least partially vaporized in the first section of the combustion area. The apparatus further includes at least one secondary burner having gas-emitting fourth and fifth regions. The fourth region of the secondary burner emits oxygen and the fifth region of the secondary burner emits a combustible gas. The second section of the conversion area is in communication with the fourth and fifth regions of the secondary burner, such that the glass-forming mixture is completely vaporized and converted into a glass soot deposited on a preform such as a bait rod. The invention also includes a method of enhanced vaporization using first and second spaced apart combustion areas.
