SEOUL — South Korea’s SK Materials has begun mass production of a crucial chipmaking gas at a purity level nearly on par with Japanese-made offerings subject to export restrictions by Tokyo, the company said Wednesday.
A plant in the South Korean city of Yeongju will produce 15 tons of etching gas per year. Samsung Electronics and SK Hynix reportedly will procure the gas for their semiconductor businesses.
This places South Korea a step closer to creating a chipmaking supply chain largely independent of Japan. Seoul aims to have homemade etching gas meet 70% of demand from domestic chipmakers by 2023.
