Ukusukela oko iJapan yaqala ukuthintela ukuthunyelwa kwezinto ezintathu eziphambili ze-semiconductor kunye nokubonisa ukuhanjiswa eSouth Korea ngoJulayi ka-2019: ubunyulu be-hydrogen fluoride ephezulu, ifluoropolyimide, kunye neefotoresist, I-South Korea inethemba lokuba ezo zinto zingenziwa kwalapha ekhaya. Imveliso yokunciphisa ukuxhomekeka kwiJapan.
NgokweshishiniKorea, iSebe lezemizi-mveliso, elezoRhwebo, kunye nezixhobo likhuphe ulwazi nge-2 kaJanuwari ukuba uMzantsi Korea useke itekhnoloji yokuvelisa ngobuninzi be-hydrogen fluoride. Ngaphambi kokuba iJapan iqinise izithintelo, abenzi bezobuchwephesha baseMzantsi Korea babexhomekeke ikakhulu kwiinkampani zaseJapan ukubonelela ngesisombululo sobunyulu be-hydrofluoric acid ngokucoceka nge-99.PA99%, esetyenziswa ikakhulu ekufakweni kweesemondondor.
Ukukhutshelwa kweJapan kwe-hydrogen fluoride eSouth Korea kwehle ngokukhawuleza emva kolawulo oluqinileyo. Ukuba itekhnoloji yokuvelisa esekwe ziinkampani zaseKorea ayinangxaki ngokubhekisele kwinzuzo nakwizibonelelo ezizinzileyo, oko kuya kubangela ithuba elide kwiinkampani ezivelisa eJapan.
Iyaqondwa into yokuba inkampani yaseMzantsi Korea yemichiza i-Soulbrain iseke isityalo esitsha e-Gongju, eChungcheongnam-do, kwaye yaqala ukuvelisa isisombululo se-hydrofluoric acid kwisiqingatha sesibini sonyaka ophelileyo. Igosa le-MOTIE lathi: "Isakhono seSoulbrain sokuvelisa isisombululo sehydrofluoric acid siphindwe kabini. Ke ngoko, kunokwenzeka ukubonelela malunga nesibini kwisithathu sezisombululo ze-hydrofluoric acid ezifunwa ngabavelisi be-semiconductor baseKorea." Le nto ivela eJapan I-South Korea ifumene imveliso yasekhaya okwesihlandlo sokuqala ukusukela kulawulo lokuthengisa ngaphandle lwenziwa kwezi mveliso zintathu. "
Umthombo wecandelo uthe: "Ngokwazi kwam, iSoulbrain ikulungele ukufezekisa imfuno yezisombululo eziphezulu zokucoceka kwe-hydrofluoric acid ezivela kubavelisi be-semiconductor yaseKorea ezinjengeM Samsung Electronics kunye ne-SK Hynix."
Nangona uMzantsi Korea ungakhange uchaze amandla athile, amajelo eendaba ase Mzantsi Korea akholelwa ekubeni isilinganiselo semveliso siya kuhlangabezana neemfuno zasekhaya zaseMzantsi Korea malunga ne-70 ukuya kwi-80%.
