Method of growing a silicon single crystal thin film in vapor phase

摘要

A method of producing a silicon single crystal thin film having a smooth surface in a stable manner in vapor-phase growth. A silicon single crystal thin film is grown by mixing silicon chloride raw material with hydrogen gas to form a process gas and supplying the process gas to a semiconductor single crystal substrate at a growth temperature, wherein the thin film is grown at a growth rate equal to or higher than 80 % of the maximum growth rate at the growth temperature. <IMAGE>
