Patent ID: 8071477

Claim:
A method of manufacturing a semiconductor device, the method comprising: loading a plurality of substrates into a process chamber, wherein the plurality of substrates are stacked and held at a predetermined interval; simultaneously supplying at least a boron-containing gas as a constituent element and a chlorine-containing gas as a constituent element to a gas supply nozzle installed in the process chamber, wherein as a result of supplying the boron-containing gas and the chlorine-containing gas, a concentration of chlorine in the gas supply nozzle is higher than a concentration of boron in the gas supply nozzle, thereby generating a compound containing the boron and the chlorine in the gas supply nozzle; forming boron-doped silicon films on the plurality of substrates by doping each of the plurality of substrates with the boron contained in the compound; and unloading the plurality of substrates from the process chamber.
