Patent ID: 8193101

Claim:
A semiconductor device manufacturing method for forming a film by using a substrate processing apparatus including: a process chamber configured to accommodate a plurality of stacked substrates; a gas supply system configured to supply a desired process gas to the process chamber; a gas discharge system configured to exhaust an inside atmosphere of the process chamber; an RF (radio frequency) unit configured to output predetermined RF power; an electrode configured to receive the predetermined RF power from the RF unit for exciting the process gas into a plasma state; and a control device configured to control the gas supply system, the gas discharge system, and the RF unit, the semiconductor device manufacturing method comprising: while controlling the RF unit by using the control device so as to apply predetermined RF power to the electrode for generating plasma, controlling the gas supply system by using the control device to supply a process gas to the process chamber alternately at a first flowrate and at a second flowrate greater than the first flowrate.
