Abstract: A semiconductor device manufacturing method comprising loading a substrate into a substrate treatment apparatus, performing a deposition process on the substrate, and cleaning the substrate treatment apparatus. The substrate treatment apparatus includes a housing defining a treatment area in which the deposition process is performed, a gas supply supplying a first process gas at a flow rate of 1000 sccm to 15000 sccm and supplying a second process gas, a remote plasma supply connected to the gas supply, generating a first process plasma and a second process plasma by applying RF power to plasma-process the first process gas and the second process gas, and a shower head installed in the housing to supply the first process plasma and the second process plasma to the treatment area. The second process plasma cleans a membrane material deposited on an inner wall of the housing.
