South Korea is heavily dependent on imported rare gases that can be mass-produced only in the United States and several other countries. The production of neon gas, which is used to make chips in the semiconductor industry, was localized by South Korea's steel group POSCO in January 2022.
Under an agreement with Arencibia, the Pennsylvania-based company that provides various upcycling solutions for industrial gases using big data-based monitoring technology, SK materials airplus will upcycle industrial exhaust gas into rare gas. "Upcycling is the best solution for stable growth considering rare gases' features such as price fluctuation and supply and demand instability," SK materials airplus CEO Oh Jong-jin said in a statement on December 19.
To secure a stable supply of neon gas, SK Hynix, the memory chip production wing of SK Group, has expanded the proportion of homemade neon gas to 40 percent in semiconductor production since a localized facility was completed in early 2022. Neon is a raw material for excimer laser gas which is used in semiconductor photolithography, a process of engraving electronic circuits on silicon wafers using ultraviolet rays with short wavelengths.
POSCO has been working with many companies to localize facilities for other imported chemical compounds such as Xenon and Krypton.
