Abstract
A number of semiconductor wafers are retained in a wafer boat such that the wafers are disposed at intervals in the vertical direction. The wafer boat is loaded into a process tube of a vertical type thermal processing apparatus. The inside of the process tube is heated to 300.degree. to 530.degree. C. in a depressurized atmosphere, and a process gas including a disilane gas is fed into the process tube such that the disilane gas flows at a flow rate of 300 SCCM or more, thereby to form silicon films.
