Claim:
1. A method of manufacturing a semiconductor device, the method comprising: mounting a processing substrate on a substrate mounting table member installed in a processing chamber that has a plurality of gas supply regions including a first processing region, a second processing region, a first purge region, and a second purge region, the first and second purge regions arranged between the first and second processing regions, wherein the plurality of gas supply regions are arranged radially with respect to a center of the processing chamber; forming a film on the processing substrate by simultaneously supplying a first processing gas from a first processing as supply unit to the first processing region and a second processing gas from a second processing gas supply unit to the second processing region; unloading the processing substrate from the processing chamber; and performing cleaning by simultaneously supplying an inert gas from a plurality of inert gas supply units to each of the plurality of gas supply regions and a cleaning gas from a cleaning gas supply unit different from the first and second processing gas supply units to all of the plurality of gas supply regions, independently controlling a flow rate of the inert gas supplied from each of the plurality of inert gas supply units to each of the plurality of gas supply regions, and controlling a density of the cleaning gas in each of the plurality of gas supply regions.
