According to the International Semiconductor Industry Association SEMI, the investment in 12-inch fab equipment expenditures in 2020 will increase by 16% compared with last year. It is predicted that the growth rate will be maintained at 16% in 2021, and will increase by another 12% in 2022 to exceed US$80 billion. Driven by the accelerated global digital transformation of the coronavirus, and with the popularization of 5G, electric vehicles, and smart wearable devices, the demand for chips in the future will usher in a spurt of demand.
Beginning in 2018, China and the United States have been fighting from trade war to technology war, and China has faced many challenges in developing the semiconductor industry. However, in addition to improving the core technology and manufacturing process of independent research and development, the development of the semiconductor industry also needs to consider factors such as basic hardware facilities and construction. Among the many links, the construction and maintenance of the clean workshop necessary for the semiconductor process is very important. In addition to the need to maintain the clean room in a constant temperature, constant humidity, ultra-clean and dust-free environment, its also necessary to consider the influence of the gaseous pollutant AMC.
Classification of AMC
With the continuous upgrade and iteration of the manufacturing process, the control of particulate matter alone can no longer improve the yield. The control technology of the AMC (Airborne Molecular Contamination) has become a necessary means to improve the semiconductor yield. Since 2005, MayAir's gaseous filtration business unit has been committed to serving fabs in mainland China, including a leading integrated circuit manufacturing company in China.
Founded in 2000, the company is a well-equipped multinational integrated circuit manufacturing company in mainland China. It can provide foundry and technical services for different technology nodes from 0.35 micron to 14 nanometers, including logic chips, mixed-signal/RF transceiver chips, High voltage chip, system chip, flash memory chip, EEPROM chip, image sensor chip power management, micro electromechanical system, etc.
As the key line width dimension of wafers produced by the company has been reduced from 0.35 microns to the 14-nanometer node, slight deviations in air quality in the work area will directly affect the yield of the product. The control requirements for AMC can be said to be more and more stringent. Environmental AMC concentration has strict control indicators and long-term monitoring, and MayAir has been escorting customers' clean room AMC control to meet customer requirements.
Through more than ten years of cooperation with this customer and in line with the national strategy of chip localization, MayAir’s chemical filter division has also been intensively engaged in the research and development of chemical filters. It has invested in product research and development technology by increasing capital expenditures, and strengthened products in energy-saving, Performance and indicators in terms of noise reduction and emission reduction, and meet the conditions required by the customer group to meet the requirements of a clean environment, promote production capacity increase and product quality optimization, in order to achieve growth with customers and promote the development of "China Chip".
