What exactly are the characteristics of wafer manufacturing industry

Technology-intensive industry

1. Technology-intensive industry: Wafer manufacturing requires highly advanced technology and equipment support, including processes such as refining of high-purity silicon materials, pulling, slicing and polishing of single crystal silicon.wafer tester These processes require precise control and operation to ensure chip quality and performance.

2. Capital-intensive industry: Wafer fabrication requires a large amount of capital investment, including the purchase of advanced production equipment, the construction of clean plants, and the purchase of raw materials and ancillary products. The construction cost of an 8-inch (about 203mm) wafer fab is usually between billions and tens of billions of RMB.

3. Strict environmental requirements: wafer manufacturing on electricity,wafer probe testing water, gas and other supplies have high-quality requirements, must use double or triple circuit power supply to ensure adequate and timely supply. In addition, there are also strict requirements for the air environment, surface microseismic and plant site geological conditions.

4. Constant temperature, constant humidity, ultra-clean production environment: Due to the limitations of process conditions, many processes must be completed in constant temperature, constant humidity, ultra-clean dust-free plant. The parameters of the indoor environment need to be automatically adjusted to ensure that it is always in the best state. Therefore, the cost of the plant is high, and the production control equipment is also exceptionally advanced and expensive.

5. Drive the development of related enterprises and industries: after the completion of the wafer fab, not only its production value can reach tens of billions or even tens of billions of dollars, but also to drive the development of a large number of related enterprises.vibration isolation table Wafer manufacturing requires many raw materials and ancillary products production plant, so the completion of a wafer fab can promote the development of the local economy, and create a large number of jobs.
