    摘要: The present invention provides an optical synthetic quartz glass material which substantially does not cause changes in transmitted wave surface (TWS) by solarization, compaction (TWS delayed), rarefaction (TWS progressed) and photorefractive effect when ArF excimer laser irradiation is applied at a low energy density, e.g. at energy density per pulse of 0.3 mJ/cm2 or less. The present invention further provides a method for manufacturing the same. In order to solve the above-mentioned problems, the optical synthetic quartz glass material of the present invention is characterized in that, in a synthetic quartz glass prepared by a flame hydrolysis method using a silicon compound as a material, the followings are satisfied that the amount of SiOH is within a range of more than 10 ppm by weight to 400 ppm by weight, content of fluorine is 30 to 1000 ppm by weight, content of hydrogen is 0.1×1017 to 10×1017 molecules/cm3 and, when the amounts of SiOH and fluorine are A and B, respectively, total amount of A and B is 100 ppm by weight or more and B/A is 0.25 to 25.

    摘要: A known projection aligner for integrated circuit fabrication, in which an integrated circuit pattern image is projected on a wafer, comprises an ArF excimer laser and an optical system composed of groups of quartz glass optical members made of synthetic quartz glass. To provide a projection aligner having optical properties, such as durability, optical transmittance and the like, which are not degraded over a long time of operation and the optical system can be constructed at a low cost as a whole, it is suggested that the optical system comprises a first quartz glass optical member group whose hydrogen molecule concentration is in the range between 1.times.10.sup.17 and 5.times.10.sup.18 molecules/cm.sup.3 and a third quartz glass optical member group whose hydrogen molecule concentration is in the range between 5.times.10.sup.18 to 5.times.10.sup.19 molecules/cm.sup.3.
