Method of manufacturing silicon carbide semiconductor device

A wafer WF is mounted in a substrate holder, and the substrate holder is placed in a film forming furnace. The film forming furnace is evacuated by a vacuum pump through a gas discharge part to remove remaining oxygen as completely as possible. Then, a temperature in the film forming furnace is heated to a range of 800° C. to 950° C. under reduced pressure while an inert gas such as Ar or helium (He) is being introduced through a gas introduction part. When the temperature reaches this temperature range, an inflow of the inert gas is stopped.
