Jiji Press SEOUL (Jiji Press) — Japan has approved the first shipment of hydrogen fluoride, used in making semiconductor chips, to South Korea since tightening export controls against Seoul last month, a South Korean official said Friday.
Hydrogen fluoride is one of the three semiconductor manufacturing materials subject to the stricter controls. Before this, export approval was confirmed only for resists, another of the three.
In early August, the Japanese government green-lighted the first shipment of resists, used on semiconductor substrates, to South Korea since the tighter controls entered into force July 4.
According to the Yonhap news agency, the hydrogen fluoride shipment was made to South Korean electronics giant Samsung Electronics Co.
The fact that Japan on Thursday approved a hydrogen fluoride export to South Korea was confirmed, the Trade, Industry and Energy Ministry official said.
