[0002] In the international market, many well-known companies are committed to the research and development of piping technology inside chemical supply equipment in the semiconductor industry. These companies have advanced production processes, high-quality materials and strict quality control systems to meet the high requirements and rapid development of the semiconductor industry. In China, the semiconductor industry has also developed rapidly in recent years, which has promoted the research and development of internal piping technology for chemical supply equipment. Some domestic companies have begun to get involved in this field and have achieved certain results. However, compared with leading international companies, domestic companies still have a certain gap in technology, materials and equipment. In order to narrow this gap, the government and enterprises have increased their investment in the research and development of related technologies in the semiconductor industry, striving to achieve independent innovation and localization. With the advancement of semiconductor process technology and the improvement of the development level of the industry, there are higher requirements for the complexity and refinement of the piping inside chemical equipment. The result is an increase in the space occupancy rate inside the equipment. When the equipment is debugged and operated, it is necessary to frequently tighten or loosen the valve to open and close it.
