SK Hynix shifts away from Japanese input material with Korean product

SK Hynix shifts away from Japanese input material with Korean productSouth Korea’s SK Hynix Inc has started using a high-tech material from a Korean supplier in its chipmaking process, a company official said on Wednesday, shifting away from a Japanese product for the first time. A SK Hynix official said it had selected an unnamed Korean company to supply high-purity hydrogen fluoride (HF), which is used in etching silicon materials and cleaning chips. South Korean chipmakers have been looking for ways to cut their reliance on Japanese materials since Japan imposed curbs on exports of key input products into South Korea in July.
