    摘要: Disclosed is a method of inspecting a flow rate measuring system used in a substrate processing system. The flow rate measuring system provides a gas flow path used for calculating a flow rate in a build-up method. A gas output by a flow rate controller of a gas supply unit of the substrate processing system may be supplied to the gas flow path. In the method, apart from a previously obtained initial value of a volume of the gas flow path, a volume of the gas flow path is obtained at the time of inspection of the flow rate measuring system. Then, the obtained volume is compared to the initial value.

    摘要: The present disclosure provides a method for inspecting a shower plate of a plasma processing apparatus. In the plasma processing apparatus, a gas ejection unit includes a shower plate. A plurality of gas ejection holes are formed on the shower plate. This method includes (i) setting a flow rate of gas output from a first flow rate controller, and (ii) acquiring a measurement value indicating a pressure in a flow path inside a second pressure control type flow rate controller by using a pressure gauge of the second flow rate controller in a state where the gas output from the first flow rate controller at the set flow rate is supplied to the gas ejection unit and branched between the first flow rate controller and the gas ejection unit so as to be supplied to the flow path inside the second flow rate controller.

    摘要: Throughput of the processing can be improved. A gas supply system includes a plurality of element devices which constitute the gas supply system and a base 212 on which the plurality of element devices are disposed. Some of the element devices are disposed on a surface 212a of the base 212, and the others are disposed on a surface 212b of the base 212, which is opposite to the surface 212a of the base 212. The plurality of element devices may be implemented by, for example, a flow rate controller FD and a secondary valve FV2. The secondary valve FV2 is disposed on the surface 212b, which is opposite to the surface 212a of the base 212 where the flow rate controller FD is disposed.

    摘要: A flow rate of a gas supplied into a processing vessel of a substrate processing apparatus is controlled according to a set flow rate of a first flow rate controller. The gas is also supplied into a second flow rate controller. When an output flow rate of the first flow rate controller is in a steady state, a first pressure measurement value of a first pressure gauge and a second pressure measurement value of a second pressure gauge of the second flow rate controller are obtained. A difference absolute value between the first pressure measurement value and a reference pressure value and a difference absolute value between the second pressure measurement value and a reference pressure value are calculated, and then, an average value of the difference absolute values is calculated. The difference absolute values and the average value are respectively compared with a first to third threshold value.

    摘要: A gas, whose flow rate is adjusted by a flow rate controller as a measurement target, is supplied into a processing vessel in a state that a third valve of the gas supply system provided at an upstream side of the processing vessel is opened. While the gas is continuously supplied, the third valve is closed after a pressure measurement value of a pressure gauge within a flow rate controller for pressure measurement is stabilized. After the third valve is closed, an output flow rate of the flow rate controller as the measurement target is calculated from a previously known volume of the gas supply system in which the gas supplied through the flow rate controller as the measurement target is collected and a rise rate of the pressure measurement value of the pressure gauge within the flow rate controller for pressure measurement with respect to time.
