    Abstract: A method for manufacturing an optical fiber preform including a dehydration process by photochemical reaction is provided. The method performs forming a clad and a core according to a predetermined refractive index profile by repeated deposition and sintering of soot particles by means of oxidation of soot generation gas, and a dehydration step for removing moisture and hydroxyl groups from a soot deposition region by means of photochemical reaction is executed between the deposition and sintering. The dehydration step activates dehydration gas into ionic or atomic state by irradiating light, in a wavelength range capable of inducing activation of the dehydration gas, from light source to the dehydration gas including chlorine and supplied to the soot deposition region, and then adsorbs the activated dehydration gas onto surface of the soot in order to induce dehydration reaction with moisture or hydroxyl groups.

    Abstract: 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 doped glass (20) is made by providing an O 2 doping atmosphere (26) to a silicon oxyfluoride glass (22) in a doping vessel (28). 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 contains doped O 2 molecules and which exhibits very high transmittance and laser transmission durability in the vacuum ultraviolet (VUV) wavelength region. In addition to containing fluorine and having little or no OH content, the inventive silicon oxyfluoride glass contains intersticial O 2 molecules which provide improved endurance to laser exposure. Preferably the O 2 doped silicon oxyfluoride glass is characterized by having less than 1x10 17 molecules/cm3 of molecular hydrogen and low chlorine levels.
