Semiconductors

In semiconductor processes, the application of UPVC piping accessories and control valves is crucial. The semiconductor industry has extremely stringent requirements for fluid systems, especially in terms of cleanliness, material purity, corrosion resistance, and precision of fluid control. UPVC (unplasticized polyvinyl chloride) piping accessories are widely used in the semiconductor industry due to their excellent corrosion resistance and chemical stability.

Semiconductor manufacturing involves many complex processes where fluid systems play an important role. For example, core equipment such as photolithography machines, PVD (Physical Vapor Deposition), CVD (Chemical Vapor Deposition), etching machines, as well as wafer preparation processes and facility pipeline systems, require high purity and ultra-high purity piping and valve components. These components include various types of valves, such as diaphragm valves, bellows valves, pressure reducing valves, check valves, and clean pipes and gas control equipment.

High purity valves in the semiconductor industry serve three main functions: fluid on-off control, fluid flow regulation, and fluid direction change. These valves play a critical role in the front-end process equipment and gas supply systems of integrated circuit chips, such as in etching processes and thin film deposition processes. To meet the stringent requirements of the semiconductor industry, these valves are typically made from ultra-high purity stainless steel and undergo electro-polishing and passivation to achieve good corrosion resistance.

YNTO brand valves specialize in providing fluid and control valves suitable for semiconductor processes, including pneumatic valves, electric valves, and automatic control valves.

In summary, the application of UPVC piping accessories and control valves in semiconductor processes reflects the industry's demand for highly precise and reliable fluid control systems. These systems must be capable of stable operation in extremely clean and highly precise environments to ensure the efficiency and product quality of semiconductor manufacturing.
