Popeza Japan idayamba kuletsa kutumizira kunja zinthu zitatu zofunikira za semiconductor ndikuwonetsa kupanga ku South Korea mu Julayi 2019: high-purity hydrogen fluoride, fluoropolyimide, ndi Photoresist, South Korea yakhala ikuyembekeza kuti zinthu zotere zimatha kupangidwa komweko. Kupanga kuti muchepetse kudalira Japan.
Malinga ndi bizinesi yaKorea, Unduna wa Zachuma, Zamalonda, ndi Zachuma watulutsa chidziwitso pa Januware 2 kuti South Korea yakhazikitsa ukadaulo wopanga ma hydrogen fluoride ambiri. Japan isanalowetse zoletsa, opanga ma Korea aku South Korea amadalira makampani aku Japan kuti apereke njira yodziyeretsera yokhala ndi vuto loyera la 99.PA99%, lomwe limagwiritsidwa ntchito popanga njira zopangira semiconductor.
Kutumiza kwa Japan ku hydrogen fluoride ku South Korea kunachepa kwambiri pambuyo polamulira. Ngati tekinoloje yopanga yokhazikitsidwa ndi makampani aku Korea sikhala ndi vuto lililonse pokhudzana ndi phindu komanso kupezeka kwokhazikika, zitha kuyambitsa mavuto kwa nthawi yayitali ku makampani opanga ku Japan.
Zikumveka kuti kampani yaku South Korea yopanga zida za mankhwala ku Soulbrain yakhazikitsa chomera chatsopano ku Gongju, Chungcheongnam-do, ndipo idayamba kupanga yankho la hydrofluoric acid kumapeto kwachiwiri chaka chatha. Mkulu wina wa MOTIE adati: "Kutha kwa a Soulbrain kupanga njira zowonjezera ma hydrofluoric acid kwachulukanso. Chifukwa chake, ndizotheka kupereka pafupifupi magawo awiri mwa atatu a hydrofluoric acid ofunikira opanga ma semiconductor aku Korea." "Izi zikuchokera ku Japan South Korea zakwanitsa kupanga kwanyumba koyamba kwa nthawi yoyamba kuchokera pomwe zinthu zoyendetsera kunja zinakhazikitsidwa pazinthu zitatuzi."
Wopanga makampani anati: "Monga momwe ndikudziwira, a Soulbrain ali okonzeka kukwaniritsa zosowa zapamwamba zoyera za hydrofluoric acid kuchokera kwa opanga semiconductor aku Korea monga Samsung Electronics ndi SK Hynix."
Ngakhale dziko la South Korea silinafotokoze za eni ake, atolankhani aku South Korea akukhulupirira kuti kuchuluka kwawo kudzakwaniritsa zofuna zapakhomo za South Korea pafupifupi 70 mpaka 80%.
