Ubukhulu bemakethe kanye namandla okukhiqiza i-hafnium tetrachloride ye-elekthronikhi eShayina kuyanda njalo.
Isikhungo Sokucwaninga Semboni Yokucabanga Okusha SaseShayina Sikhishwe ngoMashi 5, 2026
I-hafnium tetrachloride yebanga le-elekthronikhi ibhekisela ku-hafnium tetrachloride emsulwa kakhulu enokuhlanzeka okungu-99.95% noma ngaphezulu.
I-Hafnium tetrachloride, ngefomula yama-moleculeI-HfCl4kanye nesisindo sama-molecule angu-320.302, iyimpuphu emhlophe ekristalu. Iyagqwala futhi ingashisa amehlo nesikhumba. Iyacasula futhi uhlelo lokuphefumula. Inezinga lokuncibilika elingu-320°C futhi ingancibilikisa. Incibilika kalula ezinyibilikisini eziphilayo ezifana ne-methanol ne-acetone. Isabela namanzi ukuze ikhiphe amagesi anobuthi. I-hygroscopic futhi ibola kalula uma ivezwa emoyeni futhi kumele igcinwe esitsheni esivaliwe.
“Ucwaningo Olukhethekile Lwemakethe Ye-Electronic Hafnium Tetrachloride Yebanga Le-2025 kanye Nombiko Wesiphakamiso Se-Enterprise ' 15th Five-Year-Year'” olukhishwe yi-New Thinking Industry Research Center, i-electronic grade hafnium tetrachloride isetshenziswa kakhulu embonini ye-semiconductor njengento eyandulela i-semiconductor. Ifakwa futhi ikhuliswe njengamafilimu amancane asekelwe ku-hafnium esebenzisa izinqubo ezifana ne-atomic layer deposition (ALD) kanye ne-chemical vapor deposition (CVD). Amafilimu amancane asekelwe ku-Hafnium ane-dielectric constant ephezulu, okwenza abe ngenye yezinto ezibalulekile zokukhiqiza ungqimba lwe-gate dielectric lwama-transistors amancane, asebenza kahle kakhulu esizukulwaneni esilandelayo. I-electronic grade hafnium tetrachloride ingahlangabezana nomkhuba wokuthuthukiswa kwezinqubo zokukhiqiza ama-chip ezincipha njalo, futhi indawo yayo yemakethe iyanda njalo. Ngaphezu kwalokho, ngenxa yezakhiwo zayo ezinhle kakhulu zokukhanya, izakhiwo zemishini, kanye nokuzinza kokushisa, i-electronic grade hafnium tetrachloride ingasetshenziswa futhi ekukhiqizweni kwamafilimu amancane okukhanya, ama-LED anamandla aphezulu, amadivayisi e-optoelectronic aseduze ne-infrared, kanye ne-ceramics yokushisa okuphezulu kakhulu.
Ikhwalithi yobuchwepheshe bokuhlanza ithinta ngqo ubumsulwa kanye nezinga le-hafnium tetrachloride ye-elekthronikhi. Eminyakeni yamuva nje, inani lamalungelo obunikazi ahlobene nenqubo yokuhlanza kanye nemishini yokukhiqiza i-hafnium tetrachloride ye-elekthronikhi eShayina liye landa, okuhlanganisa "ithuluzi lokulungiselela i-hafnium tetrachloride ye-elekthronikhi" kanye "nendlela yokuhlanza i-hafnium tetrachloride ye-elekthronikhi".
NgoMeyi 2025, kwenziwa isimemezelo sokugunyazwa kwelungelo lobunikazi "sendlela yokuhlanzwa kwe-hafnium tetrachloride ye-elekthronikhi". Ngaphansi kokuvikelwa kwegesi engasebenzi, i-hafnium tetrachloride eluhlaza ifakwa esikebheni se-quartz, futhi ngezinqubo ezinjengokuhlanza, ukushisa, ukuhlanzwa kwe-sublimation, kanye nokuqoqwa kokupholisa, imikhiqizo ye-hafnium tetrachloride ye-elekthronikhi enokuhlanzeka kwe-5N kanye ne-6N ingatholakala.
Emakethe yaseShayina,Ubuchwepheshe be-UrbanMines.I-limited icwaninga kakhulu, ithuthukisa, futhi ihlinzeka ngemikhiqizo ye-hafnium tetrachloride ye-elekthronikhi enezinhlayiya ezingu-≥99.9%, 99.95%, kanye no-≥99.99%.
Abahlaziyi bemboni kwa-Newthink, amandla okukhiqiza i-hafnium tetrachloride ye-elekthronikhi yaseShayina asakhula. NgoMeyi 2025, i-National Environmental Protection Administration yaseShayina yadalula ukuthi umbiko womthelela wezemvelo we-“Semiconductor New Materials Pilot Plant Project” wawuzovunyelwa futhi umenyezelwe, kanti ezinye izinkampani ezihamba phambili embonini nazo ziyanda ngenkuthalo ziye emakethe ye-hafnium tetrachloride ye-elekthronikhi.
