2. Application and advantages of gas mass flowmeter in the semiconductor industry

Gas mass flowmeter plays a key role in the semiconductor industry, with a wide range of application scenarios and significant advantages, as follows: Application of gas mass flowmeter in the semiconductor industry Gas supply and control Semiconductor manufacturing requires the use of various gases such as nitrogen, hydrogen, argon, etc. Gas mass flowmeter can accurately measure and control the flow rate of these gases, ensuring stable gas supply during the manufacturing process. For example, in the chemical vapor deposition (CVD) process, fluctuations in gas flow rate can lead to uneven film thickness, affecting device performance. Gas mass flow meters can prevent such process abnormalities and ensure product quality. Cleaning and drying wafers and equipment require strict cleaning and drying to remove impurities and moisture. Gas mass flow meters ensure optimal cleaning and drying effects by accurately controlling the gas flow rate during the cleaning and drying processes. In the wafer cleaning process, controlling the flow rate of isopropanol (IPA) vapor can effectively remove surface moisture from the wafer and avoid residual water stains affecting subsequent processes. Gas mixing is a specific semiconductor process that requires mixing multiple gases in a certain proportion for use. The gas mass flow meter and gas mass flow controller work together to monitor and adjust different gas flow rates in real time, ensuring accurate control of the mixed gas ratio. For example, in the doping process, accurately controlling the mixing ratio of borane and silane can

achieve accurate doping concentration and ensure the electrical performance of the device. Gas purification and monitoring: Gas mass flow meters can detect impurities and pollutants in gases, assisting in gas purification. At the same time, it can monitor changes in gas flow rate in real time, and immediately issue an alarm when abnormal flow or leakage is detected, in order to repair it in a timely manner and ensure the stability and safety of the manufacturing process. In high-purity gas supply systems, pipeline leaks can be detected in a timely manner by monitoring flow changes, avoiding gas waste and safety accidents. In semiconductor manufacturing, gas leakage and improper use can lead to environmental pollution and increased energy consumption. Gas mass flow meters accurately measure and control gas flow, which helps reduce gas waste and emissions and achieve green production. For example, optimizing gas usage can reduce energy consumption and waste disposal costs in factories. The advantages of gas mass flow meters are that the accuracy of high-precision gas mass flow meters can reach ± 0.5% FS, which is much higher than other types of gas flow meters. High precision ensures the accuracy and reliability of measurement results, providing a solid quality assurance for the semiconductor manufacturing process. For example, in the photolithography process, high precision is required for gas flow rate, and even small flow rate deviations can cause deformation of the photolithography pattern, affecting chip yield. Independent of environmental factors, its measurement results are not affected by temperature, pressure, and density changes, and can maintain stable performance under different working conditions without frequ
