    摘要: Prior to formation of a polysilicon film on a wafer, a pre-coat film having a thickness of 1 .mu.m and consisting of polysilicon is formed on the inner wall surface of a reaction tube or the surface of a member incorporated in the reaction tube. A polysilicon film is formed on the wafer at a temperature of 450.degree. C. to 650.degree. C. A cleaning gas containing ClF.sub.3 having a concentration of 10 to 50 vol. % is supplied into the reaction tube at a flow rate to an area of an object be cleaned of 750 to 3,500 SCCM/m.sup.2 to remove a polysilicon film deposited on the inner wall surface of the reaction tube or the surface of the member incorporated in the reaction tube by etching using the ClF.sub.3. In this case, the cleaning gas is supplied while a temperature in the reaction tube is kept at a temperature of 450.degree. C. to 650.degree. C. and in a pressure condition set at the kept temperature such that an etching rate of a polysilicon film by the cleaning gas is higher than an etching rate of quartz constituting the reaction tube or the member incorporated in the reaction tube.

    摘要: In order to form a film on a surface of a semiconductor wafer, a multiplicity of wafers are individually mounted on ring-shaped mounts of a wafer boat, while the temperature within a reaction tube is set at, e.g., 400.degree. C. under a nitrogen gas atmosphere. After loading the wafer boat into the reaction tube, the temperature within the reaction tube is raised up to, e.g., 620.degree. C. at a rate of, e.g., 100.degree. C./min, and SiH.sub.4 gas is supplied onto the surface of a silicon substrate to form a polysilicon film. After film formation, air is forced to flow along the internal surface of the heating section to forcibly cool the interior of the reaction tube. In the case of forming a metal silicon film using a wafer having a silicon substrate and a metal film formed on the surface of the silicon substrate, the temperature within the reaction tube is set at, e.g. 100.degree. C. for loading the wafers. This suppresses the growth of a natural oxidation film and improves characteristics of a semiconductor device. The same principle may apply to an oxide film formation and an impurity dispersion.
