High purity helium is a gas widely used in high-purity and technological fields, including the manufacturing process of computer chips and optical fibers. In the manufacturing process of computer chips, high-purity helium gas is often used as a testing tool to check for minor defects or vulnerabilities in the chip. In addition, high-purity helium can also be used as a filler for optical fibers to improve the stability and reliability of their transmission signals.

Firstly, let's understand the application of high-purity helium gas in computer chip manufacturing. In the process of integrated circuit manufacturing, chips must undergo rigorous testing procedures to verify their integrity and reliability. To detect minor defects or vulnerabilities, manufacturers typically inject high-purity helium gas into the chip and monitor it through testing instruments. Due to its small atomic radius, high-purity helium can flow and penetrate into extremely small defects in chips, allowing manufacturers to more accurately determine if there are any issues with the chips. This testing process is called High Purity Helium Flux Leakage Test (HeMT) or Helium Leakage Scan.

Secondly, let us understand the application of high-purity helium gas in optical fiber manufacturing. Fiber optic is an effective way of transmitting optical signals. It achieves this by transmitting optical signals along a slender transparent fiber. In order to improve the stability and reliability of optical fiber transmission signals, manufacturers usually inject high-purity helium gas into the fiber to fill it. This is because high-purity helium gas has a very low density, which means it can reduce the refractive index in optical materials, thereby reducing signal scattering and attenuation. In addition, high-purity helium gas can also reduce thermal distortion in optical fibers, thereby improving their signal transmission efficiency.

In summary, high-purity helium gas is a very important gas widely used in the manufacturing process of computer chips and optical fibers. High purity helium gas can play an important role in detecting chip manufacturing defects and improving fiber optic signal stability, helping manufacturers produce higher quality and more reliable computers and communication systems
