Valves for Semiconductor Applications
Semiconductor valves have to meet a range of requirements beyond simply turning on and off. They must also be capable of maintaining the integrity and cleanliness of the liquid in question, permitting no substances such as iron particles from contaminating the stream.
Jwellok’s valves satisfy the Engineers’ needs about designing reliable fluid distribution systems within chip fabrication facilities. Our cast and forged stainless steel valves, used in numerous high-stress applications, are proven solutions for the demands of modern semiconductor manufacturing facilities.
Semiconductor valves have to meet a range of requirements beyond simply turning on and off. They must also be capable of maintaining the integrity and cleanliness of the liquid in question, permitting no substances such as iron particles from contaminating the stream. The valves in question in some cases must also be self-draining or even threadless to prevent bacteria from growing inside.
Jwellok valves products have been tested and proven across numerous industries.
Our cast and forged stainless steel valves have been used in saltwater disposal wells and on offshore platforms thanks to their superior corrosion resistance properties.
Jwellok supplies valves to the petrochemical industry, where a diverse mix of substances – including feedstock, chemicals, pollutants and more – are frequently used in highly sophisticated.
High-purity gas valves and fittings are widely used in the semiconductor industry, mainly involving the following aspects:
Precise control of gas flow and pressure: High-purity gas valves and fittings are used to precisely control gas flow and pressure in the semiconductor manufacturing process to ensure the stability and consistency of process parameters. These valves and fittings need to have high-precision control and anti-leakage functions to prevent gas contamination and leakage from affecting the manufacturing process.
Control during cleaning and flushing: During the cleaning and flushing process in semiconductor manufacturing, high-purity gas valves and fittings are used to precisely control the flow and pressure of cleaning liquids and flushing agents. These valves and fittings need to have the characteristics of corrosion resistance, high pressure resistance, and good sealing to ensure the smooth progress of the cleaning and flushing process.
Handling of special gases: In the semiconductor manufacturing process, special gases such as silane, phosphine, chlorine, etc. are required. High-purity gas valves and fittings are used to handle these special gases, and they need to have excellent corrosion resistance and high purity characteristics to prevent the entry of contaminants and ensure the purity and quality of the gas.
Control of vacuum systems: In semiconductor manufacturing, vacuum systems are used in transportation and reaction processes. High-purity gas valve fittings are used to control the gas flow and pressure of the vacuum system. They need to have high sealing and corrosion resistance to ensure the normal operation and stability of the system.
Fluid control of chemical reaction chambers: In chemical reaction chambers in semiconductor manufacturing, high-purity gas is usually required as the reaction medium. High-purity gas valve fittings are used to control the gas flow and pressure in the reaction chamber. They need to have the characteristics of corrosion resistance, high temperature resistance, and high pressure resistance to ensure the smooth progress of chemical reactions.
In general, high-purity gas valve fittings are widely used in the semiconductor industry and can meet the process requirements of high precision, high purity, high temperature and high pressure. In specific applications, it is necessary to select suitable high-purity gas valve fittings according to the requirements of different processes, and ensure that they have the characteristics of corrosion resistance, high pressure resistance, and good sealing.
