Embodiment
[0038] like figure 1 As shown, the present invention mainly includes the following steps: construction preparation, clean area setting, pipeline processing, pipeline installation, gas device installation, pipeline and gas device connection, grounding system installation, system performance testing and computer control system debugging. The above steps will be described in detail below.
[0039] (1) Construction preparation
[0040] According to the different characteristics of semiconductor process gases, the corresponding gas cabinets, valve boxes, pipe fittings, and valves must be purchased from designated manufacturers and sealed in packaging. Portable metal spectrometer is used to re-inspect the pipes, pipe fittings, and valves to detect relevant parameters such as strength, airtightness, impurities, and chemical intergranular corrosion. The materials can only be put into construction after passing the inspection. All materials should be packed with double-layer film to ...
