Abstract: PURPOSE:To reduce the difference in a temperature on the surface of a semiconductor wafer and to eliminate an irregularity in the thickness of an SiO2 film by a method wherein a heating means which can heat an inert gas up to a heating temperature region of the wafer is installed additionally. CONSTITUTION:A tantalum heater 10 is installed additionally at a gas supply tube on the upstream side of an intermediate nozzle 7 used to purge N2 gas; its heating temperature is controlled by using a controller 11 which adjusts the electric current of a power supply. The controller 11 of the tantalum heater 10 is constituted so as to execute an output control operation by a signal from a temperature sensor which measures the temperature of the N2-gas supply tube and so as to execute a closed-loop control operation which feeds back a signal from an atmospheric temperature sensor inside a muffle installed additionally near the tip of an outermost circumferential nozzle 8 for O2-gas supply use. O2 gas, SiH4 gas an N2 gas are fed from individual supply nozzles 6, 7, 8; the N2 gas out of them is supplied after it has been heated up to the same temperature region as that of a heated semiconductor wafer 2. It is possible to prevent an irregularity in the surface temperature, of the semiconductor wafer, which is considered so as to largely influence an irregularity in a film thickness.
