Abstract

The invention provides a detection method and detection device of gas transmission equipment and the gas transmission equipment. The detection method includes the steps of controlling an air inlet of a machine flow control device to be connected with a first air inlet pipeline, and controlling an air inlet valve of the air inlet to be opened and a gas transmission valve of the machine flow control device to be closed; controlling an air exhaust valve of the machine flow control device to be opened, and controlling the air exhaust valve to be closed after the flow of first gas passing through a mass flow controller in the machine flow control device reaches a preset target value; acquiring a first flow minimum value of the first gas passing through the mass flow controller within a first preset duration; and determining a valve leakage detection result, an air inlet pipeline blockage detection result and a mass flow controller installation direction detection result of the machine flow control device according to the first flow minimum value. According to the embodiment of the detection method and detection device of the gas transmission equipment and the gas transmission equipment, the three detection results of the gas transmission equipment can be obtained through one-time detection.

Description

technical field [0001] The present disclosure relates to the technical field of semiconductor manufacturing, and in particular, to a detection method, a detection device, and a gas transmission device for gas transmission equipment. Background technique [0002] In the manufacturing process of semiconductor memory devices, thin film deposition techniques need to be frequently applied. Thin film deposition techniques generally include PVD (Physical Vapor Deposition, physical vapor deposition), CVD (Chemical Vapor Deposition, chemical vapor deposition). In the chemical vapor deposition process, the factory provides the special gas cylinders required for the process reaction, so that the gas in the gas cylinders flows through the gas cabinet (Gas Cabinet) and pipelines to the mass flow controller (MassFlow Controller, MFC), and then to the distribution plate (showerhead) enters the reaction chamber to participate in the reaction for thin film deposition. [0003] Mass Flow Co...
