摘要:
PROBLEM TO BE SOLVED: To provide synthetic quartz glass for vacuum UV light which has excellent durability to irradiation with vacuum UV light, a method for manufacturing the same, and a mask substrate for the vacuum UV light using the same. SOLUTION: The synthetic quartz glass for the vacuum UV light characterized in that the internal transmittance to the vacuum UV light of a wavelength 157 nm is >=50% per 1 cm and the ratio of lowering of the internal transmittance is shots of the vacuum UV light of the wavelength 157 nm at an energy density of 0.1 mJ/cm , and the method for manufacturing the same and the mask substrate for the vacuum UV light using the same are used.
