Method for manufacturing semiconductor substrate

A consistent reduction in temperature in an SOI substrate manufacturing process is achieved.A gate oxide film provided on an SOI substrate is obtained by laminating a low-temperature thermal oxide film 13 grown at a temperature of 450° C. or below and an oxide film 14 obtained based on a CVD method. Since the thermal oxide film 13 is a thin film of 100 Å or below, a low temperature of 450° C. or below can suffice. The underlying thermal oxide film 13 can suppress a structural defect, e.g., an interface state, and the CVD oxide film 14 formed on the thermal oxide film can be used to adjust a thickness of the gate oxide film. According to such a technique, a conventional general silicon oxide film forming apparatus can be used to form the gate oxide film at a low temperature, thereby achieving a consistent reduction in temperature in the SOI substrate manufacturing process.
