Kusukela iJapan yaqala ukukhawulela ukuthunyelwa kwezinto ezintathu ezibalulekile ze-semiconductor kanye nokukhiqizwa okwenziwa eSouth Korea ngoJulayi 2019: ubumsulwa obukhulu be-hydrogen fluoride, i-fluoropolyimide, ne-Photoresist, iSouth Korea bebenethemba lokuthi izinto ezinjalo zingenziwa endaweni yakini. Ukukhiqiza ukunciphisa ukuncika eJapan.
Ngokusho kwebhizinisiKorea, uMnyango Wezimboni, Wezentengiselwano, kanye Nezinsizakusebenza wakhipha imininingwane ngoJanuwari 2 ukuthi iNingizimu Korea isungule ubuchwepheshe bokukhiqiza kakhulu i-hydrogen fluoride ephezulu kakhulu. Ngaphambi kokuthi iJapan iqinise imikhawulo, abenzi be-chip baseNingizimu Korea ikakhulukazi babencike ezinkampanini zaseJapan ukuhlinzeka nge-high-pureity purity hydrofluoric acid solution yokuhlanzeka engu-99.PA99%, esetshenziselwa ukufeza kakhulu izinqubo zokukhiqiza ze-semiconductor.
Ukuthunyelwa kweJapan kwe-hydrogen fluoride eSouth Korea kwehle ngokushesha ngemuva kokuqiniswa kwezilawuli. Uma ubuchwepheshe bokukhiqiza obusungulwe yizinkampani zaseKorea bungenazinkinga maqondana nenzuzo kanye nokunikezwa okuzinzile, kungahle kube nomphumela wesikhathi eside ezinkampanini zokukhiqiza zaseJapan.
Kuyaqondakala ukuthi inkampani yamakhemikhali aseNingizimu Korea iSoulbrain isungule isitshalo esisha eGongju, eChungcheongnam-do, yaqala ukukhiqiza isixazululo se-hydrofluoric acid engxenyeni yesibili yonyaka ophelile. Isikhulu se-MOTIE sithe: "Amandla weSoulbrain ukukhiqiza izixazululo ze-hydrofluoric acid seliphindeke kabili. Ngakho-ke, kungenzeka ukuthi unikeze cishe izingxenye ezimbili kwezintathu zezixazululo ze-hydrofluoric acid ezidingeka abakhiqizi base-Korea semiconductor." "Lokhu kuvela eJapan South Korea esethole ukukhiqizwa kwasendaweni okokuqala ngqa selokhu kwaqaliswa ukulawulwa kwempahla ethunyelwa kule mikhiqizo emithathu."
Umthombo wezimboni uthe: "Ngokwazi kwami, iSoulbrain isilungele ukubhekana nesidingo sezisombululo eziphezulu zokuhlanzeka kwe-hydrofluoric acid ezivela kubakhiqizi be-semiconductor baseKorea njengeSamsung Electronics neSK Hynix."
Yize iSouth Korea ingazange iveze amandla athize, abezindaba zezomnotho zaseNingizimu Korea bakholelwa ukuthi izinga lokukhiqiza lizohlangabezana nezidingo zasekhaya zaseNingizimu Korea ezingaba ngu-70 kuya ku-80%.
