According to the different preparation methods and application areas, industrial gases can be divided into bulk gases and specialty gases: Industrial Gases Industry Chain The upstream raw materials of the industrial gas industry are mainly air, industrial waste gas, basic chemical raw materials, etc. The upstream industries are mainly equipment suppliers (air separation equipment, purification equipment, storage tanks and other storage container equipment, tanker trucks and other transportation equipment), electric power suppliers, and basic chemical raw material suppliers. The downstream industries of the industrial gas industry are mainly electronic semiconductor, biomedicine, new energy, metallurgy, chemical industry, machinery, electric power, building materials, lighting, food, agriculture and other industries, with a wide range of downstream applications, the economic fluctuations of a single downstream industry have less impact on the industrial gas industry. Among them, the end-user market of common industrial gases is mainly concentrated in traditional industries such as metallurgy and chemical industry, while the end-user market of specialty gases is mainly in the fields of electronic semiconductor, biomedicine and new energy.

Semi-automatic switching device is applied to decompression gas supply of double-sided high-pressure gas cylinders to realize continuous gas supply with blowing function by automatic switching, which is widely used in the fields of semiconductors and electronics, medical treatment, gene technology, biopharmaceuticals, scientific research and so on. The automatic switchover is an open disk for the delivery control of common, inert and bulk gases. All centralized gas supply systems are ideally suited for the use of automatic switching panels. An uninterrupted gas supply is absolutely essential in a number of critical manufacturing and laboratory processes. Suspension of the gas supply in any way can result in failed or ruined experiments, loss of productivity and even downtime for the entire facility. Semi-automatic switching systems are able to minimize costly downtime by switching from a primary or backup cylinder without interrupting the gas supply. Once the primary cylinder or bank of cylinders is depleted, the system automatically switches to the backup cylinder or bank of cylinders for continuous gas flow. The user then replaces the air cylinder with a new one while gas still flows from the reserve side. A bi-directional valve is used to indicate the primary or reserve side when changing cylinders.

As the semiconductor market grows, standards for purity and accuracy become more stringent. One of the determining factors in the quality of semiconductor manufacturing is the gases used in the process. These gases play many roles in the manufacturing process, including:   Precision process control   Contamination prevention   Metallurgical property enhancement   To perform these roles effectively, the gas supply and distribution system must be efficient. The design of gas handling systems used in semiconductor manufacturing must be supported by robust components and customized assemblies to ensure reliable and high quality production of semiconductors. Gases used in semiconductor manufacturing The process of manufacturing semiconductors requires the use of different gases at different stages of the process.   While common gases such as nitrogen, hydrogen, argon and helium can be used in their pure form, certain processes may require specialized mixtures. Silanes or siloxanes, hexafluorides, halides and hydrocarbons are a few of the specialty gases used in semiconductor manufacturing. Many of these gases can be hazardous or highly reactive, creating challenges in the selection and design of components for gas systems.   Here are some examples: Hydrogen and helium can easily leak from piping and fitting systems due to their small atomic size and weight.   Silanes are highly flammable and can spontaneously combust (autoignite) in air.   Nitrogen difluoride used in the deposition, etching and chamber cleaning stages becomes a potent greenhouse gas when leaked into the environment.   Hydrogen fluoride (etching gas) is highly corrosive to metal piping.   Trimethylgallium and ammonia can be difficult to handle - small fluctuations in their temperature and pressure requirements can affect the deposition process.   Controlling process conditions to minimize the negative effects of these gases must be a top priority during system design. It is equally important to use the highest quality components such as AFK diaphragm valves during the build process.   Addressing System Design Challenges   Semiconductor grade gases are in most cases of high purity and provide inert conditions or enhance reactions at different stages of the manufacturing process, such as etch and deposition gases. Leakage or contamination of such gases can have negative effects. Therefore, it is critical for the system components used to be hermetically sealed and corrosion resistant as well as have a smooth surface finish (electrolytic polishing) to ensure that there is no possibility of contamination and that an extremely high level of cleanliness can be maintained. In addition, some of these gases can be heated or cooled to achieve desired process conditions. Well-insulated components ensure temperature control, which is critical for efficient performance of the final product.   From the source inlet to the point of use, AFK's wide range of components support the ultra-high purity, temperature, pressure and flow control required in semiconductor cleanrooms and vacuum chambers.   Designed Systems with Quality Components in Semiconductor Fabs   The role of quality components and design optimization is critical to the precise control and safe manufacture of semiconductors. The components used need to be robust and leak-free to match the varying process conditions required at different stages of manufacturing.AFK's high-quality valves, fittings, regulators, piping, and sealing brackets are characterized by the following features:   Ultra-high purity   Leak-free seals   Temperature controlled insulation   Pressure control   Corrosion resistance   Electrolytic polishing treatment

The different chemicals and gases used in semiconductor manufacturing require robust fluid systems for uninterrupted supply at every stage of production. These fluid systems must be able to support the extreme process conditions required for semiconductor manufacturing while ensuring a clean, leak-free and controlled process. Therefore, the selection of fluid system components is critical in the precision semiconductor manufacturing process. Choosing high quality fluid system components is synonymous with increased manufacturing efficiency and reduced system downtime. With respect to the semiconductor manufacturing process, we will discuss the critical role of fluid system components and the importance of their reliability.   Importance of Fluid System Components in Semiconductor Manufacturing   Fluid system components in semiconductor manufacturing include different chemical mixing, conveying, and control systems for safely transporting chemical fluids in a controlled environment. An ideal fluid system has:   ➢ Uniform chemical mixing   ➢Contamination control   ➢Temperature and pressure control   ➢Uninterrupted chemical supply   Only the highest quality components can provide such ideal conditions in a semiconductor fluid system. The advantages of using such components include: Accurate: Components such as valves, regulators and pumps work in tandem to ensure that the correct proportion of chemical is delivered to the production cell. Precise inputs eliminate the risk of flow variations, which improves the quality of the final product.   Compatibility and cleanliness: Fluid system components with material compositions that are compatible with process fluids reduce the risk of contamination. In addition, the leak-free installation of these fluid system components reduces particulate contaminants, providing a clean and controlled manufacturing environment for improved yields.   Safety: Gases and chemicals used in semiconductor manufacturing can be harmful to human health. However, fluid system components designed to prevent leaks and spills can deliver these fluids to production units in a safe and controlled manner.   Efficiency: The leak-free construction and precise control of high-quality fluid system components minimizes operational downtime and frequent maintenance requirements, promoting smooth, efficient manufacturing to meet production goals.   Quality Manufactured Fluid System Component Solutions   Fluid system components require high quality installations to meet the challenges of semiconductor manufacturing. Key components that impact the fab include:   Valves: High-performance valves, such as diaphragm, bellows, or needle valves, ideally regulate fluid flow in manufacturing facilities. Durable, high-quality valves provide the precision and control needed to improve the efficiency of production and handling processes for critical semiconductor manufacturing.   Fittings: High-purity fittings for tubing and hose systems and other critical components provide sealed connections to enhance the safety and purity of fluid system components.   Hoses: For precision manufacturing requirements, insulated hoses aid in thermal management so that process conditions within the production room can be optimally maintained. This is important because the slightest temperature fluctuation can damage chips and lead to production waste.   Flexible Tubing: Where conditions allow, flexible tubing can be used to reduce the number of fittings in a fluid system assembly. The tubing is bent to obtain the desired fluid path. Fewer fittings means less risk of leaks and damage due to vibration and movement.   Regulators: Regulators effectively control pressure at each stage of the semiconductor manufacturing process. Constant and accurate flow achieves consistent, high-quality yields while avoiding wasted fluid chemicals and specialty materials.   Filters: A single particle can affect semiconductor performance. The use of ultra-high purity filters eliminates particle contamination and minimizes chip damage.   Fluid system efficiencies in semiconductor manufacturing can be achieved with AFK-LOK's wide range of high quality valves, fittings, regulators, hoses and filters.

Using gases can be dangerous. Gas leaks or gas contamination are serious events that can lead to fire, explosion, personal injury or even death. All of these outcomes jeopardize the safety of on-site employees and risk damaging or destroying valuable equipment and property. Additionally, natural gas issues can leave an organization vulnerable to liability and regulatory fines. Accidents can occur due to operators disconnecting the wrong cylinders, or forgetting to disconnect cylinders and ignoring gas leaks. However, with the right equipment, these errors can be minimized to protect operators and maintain safety. Gas Safety Standards in Semiconductor Manufacturing Semiconductor manufacturing is one of the industries that must focus on gas handling safety. Semiconductor factories use a variety of gases in their production processes, making it imperative to ensure worker safety in day-to-day operations. Regardless of the stage of the semiconductor supply chain, vigilance is essential!   WOFLY recommends the following safety precautions when using gases in semiconductor manufacturing:   Identify exhaust hazards and conduct appropriate exposure assessments. - Identify and evaluate all potential exposure scenarios (e.g., startup, operation, maintenance, cleaning, emergencies). - Review the end pages of the WOFLY brochure, which contains permissible exposure limits for various substances.   -Provide proper ventilation to reduce airborne gas concentration levels.   -Provide personal protective equipment (PPE) as appropriate to prevent exposure to exhaust gases.   -Use respiratory protection where necessary to further minimize exposure and protect employees.   Choosing the right equipment for your facility is also critical to preventing hazardous gas exposure. The right tools will not only prevent hazardous incidents, but also improve operations and efficiency. Ensure operator safety with the right equipment The safety of a wafer fab depends on its equipment and having the right tools is essential to maintain a safe, reliable and efficient process.GAS monitoring boxes are one of the most important pieces of equipment for preventing unintentional gas leaks.

The origin of gas pressure regulators can be traced back to the mid-19th century with the development of devices to control and regulate gas flow and pressure in various applications. The early gas pressure regulators were primarily used in gas lighting systems, which were prevalent during that time.   One of the notable pioneers in the development of gas pressure regulators was Robert Bunsen, a German chemist and inventor. In the 1850s, Bunsen invented the Bunsen burner, a widely used gas burner in laboratories. The Bunsen burner incorporated a rudimentary pressure regulator mechanism to control the gas flow and maintain a stable flame. Over time, as gas utilization expanded into various industries and applications, the need for more advanced and precise gas pressure regulation arose. This led to the development of more sophisticated gas pressure regulators with improved control mechanisms.   The modern gas pressure regulators we see today have evolved through advancements in engineering, materials, and manufacturing techniques. They incorporate features such as diaphragm or piston-based control mechanisms, pressure sensors, and safety features to meet the diverse requirements of different industries and applications.   Today, gas pressure regulators are produced by several manufacturers worldwide, specializing in various types and sizes to cater to specific needs. These regulators undergo rigorous testing and certification processes to ensure their performance, reliability, and compliance with safety standards.   Overall, the origin and development of gas pressure regulators can be attributed to the increasing demand for controlled gas flow and pressure in various industries, evolving from basic mechanisms to sophisticated devices we rely on today.

Nowadays more and more industries need to use ultra-high purity gases, and many companies began to research and manufacture valves used to regulate high-purity gases, so there is a pressure control valve. The materials used in this regulating valve are of high quality, including the diaphragm fittings made of Hastelloy and the entire valve body made of stainless steel 316L. Continuous testing has resulted in a pressure regulator with VCR fittings for tight sealing performance, precise pressure control, precise flow control, ultra-high purity requirements, corrosion resistance, reliability and stability. Nowadays, the application range of ultra-high-purity pressure regulators is also quite wide, and its application markets are as follows Semiconductor industry: The semiconductor industry has very strict requirements for ultra-high purity gases, and ultra-high purity pressure regulators play a key role in the semiconductor manufacturing process. They are used to control and regulate the pressure of high-purity gases (such as nitrogen, hydrogen, argon, etc.) used in semiconductor manufacturing to ensure stable process conditions and optimal production quality.   Photovoltaic industry: In the photovoltaic (solar) industry, ultra-high purity pressure regulators are used to control and regulate the pressure of gases used in the manufacturing process. For example, in the manufacture of solar cells, where gases are used to clean and treat surfaces, UHP pressure regulators ensure that a constant supply of gases is provided as well as proper pressure control. Pharmaceuticals and life sciences: The demand for ultra-high purity gases is also high in the pharmaceutical and life sciences sectors. UHP pressure regulators are used in pharmaceutical processes to control and regulate the pressure of gases to ensure the safety and stability of the pharmaceutical process. In addition, they are used in laboratory equipment and for research purposes.   Laboratory and scientific research: UHP pressure regulators are widely used in laboratories and scientific research to control and regulate the pressure of gases. Whether it's in a chemistry lab, physics research or materials science, UHP pressure regulators are a key piece of equipment in ensuring the accuracy and reliability of experimental and research processes.   Ultra high purity pressure regulators are used in the semiconductor industry in a significant proportion of the many application markets. As the semiconductor manufacturing process has very strict requirements for high purity gases, ultra-high purity pressure regulators play a vital role in the semiconductor industry. In the semiconductor manufacturing process, ultra-high-purity pressure regulators are used to control and regulate the pressure of high-purity gases (e.g., nitrogen, hydrogen, argon, etc.) to ensure stable process conditions and optimal production quality. There are several reasons why ultra-high purity pressure regulators make up the largest portion of the semiconductor industry: High Purity Gas Requirements: The semiconductor manufacturing process requires extremely high purity of the gases used. Tiny impurities or contaminants can have a serious impact on the performance and reliability of semiconductor devices. Ultra-high purity pressure regulators provide a high purity gas supply, ensuring that the purity of the gas is not affected by contamination or impurities.   Process Stability and Consistency Requirements: Semiconductor manufacturing is a highly accurate and stable process where precise control of gas pressure is critical. Ultrahigh-purity pressure regulators provide stable pressure output and precise adjustment of gas pressure to ensure consistency and control of semiconductor process parameters.   Fast Response and Highly Accurate Control: Certain steps in the semiconductor manufacturing process require fast gas pressure adjustments in a short period of time, while at the same time requiring highly accurate control. Ultrahigh-purity pressure regulators meet these special requirements with fast response and high-precision control.   Reliability and safety: The semiconductor industry demands the highest levels of reliability and safety from equipment and systems. Ultrahigh-purity pressure regulators are typically manufactured with high-quality materials and advanced manufacturing processes, providing excellent reliability and safety to meet the stringent requirements of the semiconductor industry.   In summary, ultra-high purity pressure regulators are widely used in the semiconductor industry, mainly to meet the demand for high-purity gases, to provide stable process control, to ensure high accuracy and fast response, and to provide high reliability and safety requirements. These features make ultra-high purity pressure regulators an indispensable key device in the semiconductor manufacturing process. Today's market price of ultra-high-purity pressure regulator is very different from high and low, the quality of good and bad, and the need for this product, some care about the price, some care about the quality, but most of the concern is still quality and price. Our brand is AFKLOK own factory, the product also did a lot of testing finally got good results, so in the price as well as quality we have an advantage, we can replace the other brands, the future we will also get better and better.

Difference between high and low flow rates of high purity gas regulators: High flow regulators are typically designed to handle higher gas flow rates, usually in liters per minute (L/min) or cubic meters per hour (m³/h). In contrast, low flow regulators are suitable for lower gas flow ranges, usually in milliliters per minute (mL/min) or liters per hour (L/h). Design of pressure regulator valves for ultra-high purity gases： Valve Design: High flow regulators typically use larger valves and passages in order to handle larger gas flows. These valves may require larger pistons, diaphragms, or other fluid control elements to achieve precise regulation of flow. Low flow regulators, on the other hand, use smaller valves and passages to accommodate lower flow requirements.   Pressure range of ultra-high purity gas pressure regulators： High flow regulators typically have a wider pressure range and can handle higher input pressures and step down to lower output pressures. Low flow regulators may have a relatively narrow pressure range for lower input pressures and achieve a smaller output pressure range.   External Dimensions of Ultrahigh-Purity Gas Pressure Regulators： Because high flow regulators are required to handle larger gas flows, they typically have larger external dimensions and heavier weights to accommodate greater fluid dynamics. In contrast, small flow regulators can be more compact and lightweight for space-constrained or mobile applications.   Areas of application for ultra-high-purity gas pressure regulators： High flow regulators are commonly used in applications that require a high flow rate of gas supply, such as industrial process control and large laboratory equipment. Low flow regulators are used in applications requiring lower flow rates and more precise control, such as laboratory analyzers, scientific research, etc.   Principle of Operation of Ultrahigh-Purity Gas Pressure Regulators： High purity gas pressure reducers typically utilize an adjustable valve and a pressure sensor. When high pressure gas enters the pressure reducer, the valve automatically adjusts the switch to reduce the pressure to the desired output pressure based on the set pressure value.   Overall, high purity gas pressure reducers are widely used in semiconductor manufacturing, optoelectronics, photovoltaic industry, nanotechnology, laboratory research, and other areas where high purity gases are required. They are used to control gas pressure and flow to meet specific process and experimental requirements.

Tail gas treatment equipment can handle gases used in etching processes and chemical vapor deposition processes in the semiconductor, liquid crystal, and solar energy industries, including SiH4, SiH2Cl2, PH3, B2H6, TEOS, H2, CO, NF3, SF6, C2F6, WF6, NH3, N2O, and so on. Exhaust gas treatment method According to the characteristics of exhaust gas treatment, the treatment can be divided into four types of treatment: 1. Water washing type (treatment of corrosive gases) 2. Oxidizing type (dealing with combustible and toxic gases) 3. Adsorption (according to the type of adsorption material to deal with the corresponding exhaust gas). 4.Plasma combustion type (all types of exhaust gases can be treated). Each type of treatment has its own advantages and disadvantages as well as its scope of application. When the treatment method is water washing, the equipment is cheap and simple, and can only handle water-soluble gases; the application range of the electric water washing type is higher than that of the water washing type, but the operation cost is high; the dry type has good treatment efficiency, and is not applicable to the gas flow that is easy to be clogged or flowed. Chemicals and their by-products commonly used in the semiconductor industry can be categorized according to their chemical properties and their different ranges: 1. Flammable gases such as SiH4H2, etc. 2. Toxic gases such as AsH3, PH3, etc. 3. Corrosive gases such as HF, HCl, etc. 4. Greenhouse gases such as CF4, NF3, etc. Since the above four gases are harmful to the environment or human body, must prevent its direct emission into the atmosphere, so the general semiconductor plant are installed with a large centralized exhaust gas treatment system, but this system is only water scrubbing exhaust, so its application is limited to the long-distance water-soluble gases, and can not deal with the ever-changing and subtle division of the semiconductor process exhaust gas. Therefore, it is necessary to select and match the corresponding exhaust gas treatment equipment according to the gas characteristics derived from each process in order to solve the exhaust gas problem in a small way. As the working area is mostly away from the central exhaust gas treatment system, often due to gas characteristics lead to crystallization or dust accumulation in the pipeline, resulting in clogging of the pipeline leading to gas leakage, and in serious cases, even cause an explosion, can not ensure that the site staff's work safety. Therefore, in the work area need to configure a small exhaust gas treatment equipment suitable for the characteristics of the process gas, in order to reduce the stagnant exhaust gas in the work area, to ensure the safety of personnel.

There are a wide variety of gases found within a pharmaceutical or medical laboratory. Many have no taste, colour or smell, which makes it difficult to tell if a gas leak is present. A gas leak from a cylinder or fixed pipe gas system poses a series risk that can cause a potentially fatal incident or hazard within a laboratory environment.   The pharmaceutical industry is one of the world’s fastest growing industries. Most of the sales revenue it generates is then reinvested in the area of research and development of new products. Research and development uses a wide range of speciality gases and equipment. Analytic instruments such as gas chromatographs, liquid chromatographs and spectrometers all rely on the appropriate level of gas delivery to operate effectively.   These pharmaceutical and medical gases are manufactured specifically for the medical, pharmaceutical manufacturing, and biotechnology industries. They are frequently used to synthesize, sterilize, or insulate processes or products which contribute to human health.   Pharmaceutical gases are also inhaled by patients in a technique known as gas therapy. Gases used for human healthcare are strictly controlled by both legislation and industrial standards so as to not impair human physiology.   Gases found within a laboratory Helium Helium (He) is a very light, odourless and tasteless gas. It is also one of the 6 noble gases (helium, neon, argon, krypton, xenon and radon), so called because they do not react with other elements and therefore cannot bond with other atoms to form complex compounds. This gives it a strong safety profile and a potential usage in multiple applications. Due to their unreactive status Helium is often used as a carrier gas in laboratories. Helium has many uses beyond its most common one to fill balloons and its role within the pharmaceutical and biotechnology sector is invaluable. It is most widely used in the laboratory in the cooling of magnets inside MRI machines however it is also used across a large range of medical areas including respiratory, cardiology, radiology and cryology functions.   Argon Argon (Ar) is also a noble gas with non-reactive properties. In addition to its well-known use in neon lights it is also sometimes used in the medical and biotechnology sectors. It is the preferred inert gas for use within Schlenk lines and glove boxes in cases where nitrogen may react with reagents or apparatus and can also be uses is the carrier gas in gas chromatography and electrospray mass spectrometry. In pharmaceuticals and medicine it can also be used in packaging where nitrogen may conflict and also in cryosurgery and in lasers used for vascular welding and correcting eye defects.   Nitrogen Although not a noble gas like Helium or Argon Nitrogen (N) is also commonly used in pharmaceutical industry due to is relatively non- reactive properties in many different processes and applications. Laboratories primarily to control the atmosphere for highly sensitive equipment and procedures. Nitrogen gas is applied to control oxygen levels, humidity, and temperature in lab equipment including cell incubators, dry boxes, glove boxes, and mass spectrometers.
