Abstract:
The invention starts from a known component of quartz glass for use in semiconductor manufacture, which component at least in a near-surface region shows a co-doping of a first dopant and of a second oxidic dopant, said second dopant containing one or more rare-earth metals in a concentration of 0.1-3% by wt. each (based on the total mass of SiO2 and dopant). Starting from this, to provide a quartz glass component for use in semiconductor manufacture in an environment with etching action, which component is distinguished by both high purity and high resistance to dry etching and avoids known drawbacks caused by co-doping with aluminum oxide, it is suggested according to the invention that the first dopant should be nitrogen and that the mean content of metastable hydroxyl groups of the quartz glass is less than 30 wtppm.
Abstract:
PURPOSE: A highly durable quartz glass, its preparation method and apparatus, a quartz glass member, and a semiconductor manufacturing device and a liquid crystal manufacturing device employing the member are provided, wherein the quartz glass is improved in durability, processability and transparency. CONSTITUTION: The quartz glass comprises 0.01-2 wt% of at least element selected from the group consisting of Mg, Ca, Sr, Ba, Y, Hf and Zr. The quartz glass is prepared by dropping the silica powder containing Zr into the furnace using an acid hydride salt as a heat source, layering it, and extending the layer outward. Also the quartz glass is prepared by passing the powder mixture of a silicate powder and the silica powder containing Zr through the plasma arc-coupling region where at least two plasma arcs are coupled and at least two electrodes have opponent polarity, or its neighborhood, thereby melting the mixture.
