An official in the Korean semiconductor industry said that Samsung, the world's largest semiconductor company, said “hydrogen fluoride” used for semiconductor cleaning, among the three semiconductor-related items that the Japanese government tightened export procedures to Korea in July. It was revealed that electronics began using domestic products as part of the manufacturing process.
Since the export procedure in Japan has been strengthened, it seems that this is the first time a Korean semiconductor giant has replaced domestic materials. The company is also starting to use foreign products other than Japan. According to another industry official, SK Hynix, a major semiconductor company, is repeatedly testing whether non-Japanese products can be used in the process.
According to the Korea Trade Association, Korea's dependence on hydrogen fluoride is over 40%, and high-purity products used for semiconductor cleaning depend on imports from Japan. The Korean government and companies are promoting domestic production and diversification of import destinations following the strengthening of Japanese export procedures. It has been pointed out that if “Leave Japan” becomes a reality, Japanese companies may be affected.
Stella Chemifa (Osaka City), which supplies hydrogen fluoride to Samsung Electronics, said on the 4th that it did not listen (information) about information that Samsung Electronics started using Korean products. The impact on future business performance is "difficult to forecast because export is not allowed" (same). (Satoshi Kamiya = Seoul, Yosuke Okawa)
