Patent ID: 8304328

Claim:
A manufacturing method of a semiconductor device comprising: loading a plurality of substrates into a processing chamber; supplying a first processing gas containing at least one element out of a plurality of elements constituting a thin film formed on a main surface of the substrate and capable of depositing a film by itself, to an upper stream side of a gas flow outside of a region where the plurality of substrates loaded into the processing chamber are arranged, also supplying the first processing gas to a middle part of the gas flow within the region where the plurality of substrates loaded into the processing chamber are arranged, by a multi-system nozzle; supplying a second processing gas containing at least one element out of the plurality of elements and not capable of depositing the film by itself, to the upper stream side of the gas flow outside of the region where the plurality of substrates loaded into the processing chamber are arranged, by a nozzle provided on the upper stream side of the gas flow, which is a different nozzle from the multi-system nozzle, and forming an amorphous material by allowing the first processing gas and the second processing gas to react with each other in the processing chamber, and forming the thin film on the main surfaces of the plurality of substrates; and unloading the substrate after forming the thin film from the processing chamber.
