Abstract:
A method of chemically growing a silicon thin film or a silicon epitaxial single crystal thin film in a gas phase on the whole surface of a silicon semiconductor substrate using a rotary gas phase thin film growing apparatus which feeds a material gas by causing the gas to flow downward such that a thin film is grown on a surface of said silicon semiconductor substrate comprising the step of:using monosilane gas as an effective component of the material gas to grow the thin film under a reduced pressure of from 2.7Ã—102 to 6.7Ã—103 Pa with rotations of said silicon semiconductor substrate being from 500 to 2000 minâˆ’1 at a reaction temperature of from 600Â° C. to 800Â° C.
