High-purity helium is a rare gas that plays a key role in semiconductor manufacturing, because of its physical and chemical inertness, it is used as a shielding gas in chemical vapor deposition, epitaxial growth, etc., and is mixed with gas gas for dry etching, ion implantation and other ionic processes and thermal management processes. This product has the advantages of ultra-high purity, which can meet the requirements of customers for a variety of packaging and cylinder joints.
