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. |

A luminescent element of next-generation optical device that by photoluminescence (PL), exhibits a large half-value width of emission spectrum in the wavelength region of visible light so as to realize broad light emitting characteristics and enables white light emission. Silica glass is produced through a firing operation for firing a product of pressure molding of silica microparticles such as fumed silica, wherein the firing temperature is regulated within a range not exceeding 1000°C so as to satisfactorily carry out dehydration condensation reaction with respect to OH groups of silica microparticles to thereby attain clearing and wherein amorphous defects having occurred during the reaction are retained without being reduced. This silica glass is used as a phosphor. |

Vacuum ultraviolet light with a wavelength of 200 nm or less is applied on the joining surfaces of first and second workpieces made from a crystal substrate and a glass substrate, or a glass substrate and a glass substrate from a light irradiation unit. The workpieces are conveyed to a workpiece cleaning and laminating mechanism by a conveyance mechanism, the joining surfaces are subjected to mega-sonic cleaning as needed, and the workpieces are aligned with the joining surfaces thereof facing each other, and laminated such that the joining surfaces are in contact with each other. After being laminated, the laminated workpieces are conveyed to a workpiece heating mechanism and heated to increase the workpiece temperature to a predetermined temperature, and this temperature is maintained until joining is completed. The laminated workpieces are brought into a thermally expanded state upon heating, and are joined in this state. |
