    摘要: Synthetic quartz glass is produced by feeding a silica-forming raw material gas, hydrogen gas, oxygen gas and a fluorine compound gas from a burner to a reaction zone, flame hydrolyzing the silica-forming raw material gas in the reaction zone to form fine particles of fluorine-containing silica, depositing the silica fine particles on a rotatable substrate in the reaction zone so as to create a fluorine-containing porous silica matrix, and heat vitrifying the porous silica matrix in a fluorine compound gas-containing atmosphere. This process enables the low-cost manufacture of a synthetic quartz glass having a higher and more uniform transmittance to light in the vacuum ultraviolet region than has hitherto been achieved.

    摘要: A process for manufacturing synthetic quartz glass involves feeding a quartz glass-forming raw material to a high-temperature gas zone within a chamber, converting the quartz glass-forming raw material into quartz soot, and forming synthetic quartz glass from the soot. A suspended soot-discharging gas which has been flow-straightened in a suspended soot discharging direction flows through the chamber in the vicinity of the high-temperature gas zone. This process keeps free suspended soot from settling onto the surface of the quartz ingot where fusion and growth take place, thereby preventing the formation of bubbles within the quartz glass under growth.

    摘要: A polyhydroxystyrene having a 2,4-diamino-s-triazinyl group substituted for 1-50 mol % of its hydroxyl group and a weight average molecular weight of 3,000-50,000 is provided. A negative radiation-sensitive resist composition comprising the polymer, preferably along with a photo-acid generator and a crosslinking agent has high resolution and developability, affords a resist pattern of rectangular profile, and is shelf stable. The composition is thus very useful as resist material for LSI manufacture.

    摘要: In a quartz glass, a mark is internally made such that a retardation generated in close proximity to the end of the mark is up to 20 nm. The internally marked quartz glass in which internal marks are created without sacrificing optical precision finds use as quartz glass substrates for optical members in the electronic industry.
