➀ Vacuum pumps are essential components in semiconductor manufacturing, categorized into low, medium, high, and ultra-high vacuum types. They operate through gas transfer and gas capture mechanisms. ➁ In the semiconductor sector, vacuum pumps are primarily classified into dry pumps, molecular pumps, and cryopumps. Dry pumps dominate the market, accounting for 60%-70%, and are crucial in various applications including integrated circuits and solar energy. ➂ The Chinese market for vacuum pumps is estimated to be nearly 10 billion yuan, driven by the semiconductor and photovoltaic industries. The market is largely dominated by foreign companies, with only a small percentage of domestic manufacturers like Hanbell Precise Machinery and ZKY holding a minimal share.
