    摘要: In a thermal treatment apparatus that accommodates substrates to be processed (W) in multiple stages within a reaction tube (4) and subjects them to a thermal treatment, thermal protection members (19) are provided around the peripheries of the substrates (W) to be processed to intercept thermal radiation that is incident on the peripheral edge portions thereof at a predetermined angle of incidence or greater. The peripheral edge portions of substrates (W) to be processed are generally more readily affected by thermal radiation as the angle of incidence of thermal radiation thereon increases, but, since thermal radiation from the heater at a predetermined angle of incidence (.theta.) or greater is intercepted by the thus disposed thermal protection members (19), the effects on thermal radiation on the peripheral edge portions of the substrates (W) to be processed are controlled. As a result, the temperature difference within the surface between the central portion and peripheral edge portion of each substrate to be processed (W) can be sufficiently reduced, not only under normal pressure within the reaction tube (4) but also under reduced pressures, and thus the temperature can be raised or lowered rapidly, enabling an increase in throughput.

    摘要: In a vertical substrate processing apparatus including a vertical reaction vessel having an open lower end, a lid closing the open lower end of the reaction vessel, a rotation shaft extending through the lid to rotate a wafer boat in the reaction vessel, a bore formed in a casing disposed below the lid to receive the rotation shaft is sealed hermetically by a magnetic sealing unit, the leakage of a gas emanated from magnetic fluid of the magnetic sealing unit into the reaction vessel is suppressed during a LPCVD process and, if the vertical processing apparatus is used for both a LPCVD process and an oxidation process, the corrosion of the components of a rotating mechanism by HCl gas is prevented. To achieve such functions, the bore is evacuated through an exhaust passage opening in to the bore at a position on the side of the reaction vessel with respect to the magnetic sealing unit. The deposition of reaction byproducts on rotating members can be prevented by supplying an inert gas, such as N.sub.2 gas, through a gas supply passage when the bore is evacuated. When carrying out an oxidation process, a purging gas is supplied through the gas supply passage into the bore to prevent leakage of HCl gas into the bore.
