ABSTRACT:
A manufacture method for a semiconductor device includes the steps of: (a) transporting a silicon wafer into a reaction chamber having first and second gas introducing inlet ports; (b) introducing an oxidizing atmosphere via the first gas introducing inlet port and raising the temperature of the silicon wafer to an oxidation temperature; (c) introducing a wet oxidizing atmosphere to form a thermal oxide film on the surface of the silicon wafer; (d) purging gas in the reaction chamber by using inert gas to lower a residual water concentration to about 1000 ppm or lower; and (e) introducing an NO or N2O containing atmosphere into the reaction chamber via the second gas introducing inlet port while the silicon wafer is maintained above 700° C. and above the oxidation temperature, to introduce nitrogen into the thermal oxide film and form an oxynitride film. A thin oxynitride film can be manufactured with good mass productivity.
