MR Chemical has become a comprehensive service provider integrating gas manufacturing, special gas customization, gas solutions, gas logistics and transportation. From application demand analysis to ratio scheme design, it runs through multiple core technologies in the entire process of gas production, purification, testing and transportation. It is widely used in metallurgy, electronics, photovoltaics, food, medical, chemical, machinery and other industrier .

In the semiconductor chip manufacturing process, the integration and performance of chips are constantly improving, and the requirements for the cleanliness of the production environment are also increasing accordingly. Ultra-pure helium gas is used as a protective gas and carrier gas in key processes such as chip etching and photolithography during the chip manufacturing process. During the chip manufacturing process, even a tiny impurity particle can cause a short circuit or open circuit in the chip circuit, resulting in the chip being scrapped. Ultra-pure helium gas, with its ultra-high purity, can effectively prevent the introduction of impurities, ensuring a high yield rate in chip manufacturing and supporting the semiconductor industry to develop towards higher precision and stronger performance. In the aerospace field, ultra-pure helium is also indispensable in the manufacturing and inspection of aircraft components. For instance, during the leak detection process of satellite components, ultra-pure helium gas is used as a tracer gas. Its high purity ensures the accuracy of the detection results. If the helium gas contains impurities, it may lead to misjudgment, affecting the reliability and safety of the satellit .
