Njengoba imboni ye-semiconductor iqhubeka nokuthuthuka iye ekusebenzeni okuphezulu, ekusebenzeni kahle kwamandla okukhulu, kanye nasezindaweni zokusebenza ezidinga kakhulu, izinto ezithuthukisiwe ziya ngokuya zibaluleke kakhulu empumelelweni yokukhiqiza. Ukukhula okusheshayo kwe-power semiconductors, izimoto zikagesi (ama-EV), izinhlelo zamandla avuselelekayo, ingqalasizinda ye-5G, kanye ne-electronics yezimboni yesizukulwane esilandelayo kuye kwasheshisa ukwamukelwa kwezinto ze-semiconductor ze-wide-bandgap ezifana ne-silicon carbide (SiC) kanye ne-gallium nitride (GaN). Lezi zinto zinikeza izinzuzo ezibalulekile kune-silicon evamile, kufaka phakathi i-voltage ephezulu yokuqhekeka, ukuhanjiswa kokushisa okuthuthukisiwe, kanye nokusebenza kahle okuphezulu ngaphansi kwezimo zokusebenza ezimbi kakhulu.
Ngemuva kwalezi ntuthuko kwezobuchwepheshe kukhona uhlelo lokukhiqiza oluyinkimbinkimbi kakhulu oluncike ezintweni ezikhethekile ezikwazi ukumelana nezimo zenqubo enamandla. Phakathi kwalezi zingxenye,I-Silicon Carbide (SiC) Crucibleidlala indima ebalulekile ekukhuleni kwekristalu okushisa okuphezulu, ukwenziwa kwezinto, kanye nezinqubo zokukhiqiza ze-semiconductor. Nakuba kuvame ukunganakwa uma kuqhathaniswa nama-wafer noma izinto ze-epitaxial, ukusebenza kwe-crucible kuthinta ngqo ubumsulwa bezinto, ikhwalithi yekristalu, ukuzinza kwenqubo, kanye nokukhiqiza kwedivayisi ekugcineni.
Iyini i-Silicon Carbide (SiC) Crucible?
I-Silicon Carbide Crucible iyisitsha se-ceramic esisebenza kahle kakhulu esenziwe ngezinto ze-SiC ezihlanzekile kakhulu. Yenzelwe ngqo ukusebenza ngaphansi kwezimo ezishisayo kakhulu nezamakhemikhali lapho izinto ezivamile zingase zehluleke khona. I-Silicon carbide inikeza inhlanganisela eyingqayizivele yokumelana nokushisa okuphezulu, ukuhanjiswa kokushisa okuhle kakhulu, amandla aphezulu omshini, kanye nokungangeni kahle kwamakhemikhali okuvelele. Lezi zici zivumela ama-crucible e-SiC ukuthi alondoloze ubuqotho besakhiwo kanye nokuqina kobukhulu ngisho noma evezwe emazingeni okushisa angaphezu kuka-1,600°C, okwenza abe afaneleka kakhulu ekukhiqizweni kwe-semiconductor okuthuthukisiwe.
Ukusetshenziswa Okuvamile Kweziqhumane Ze-SiC Ekukhiqizweni Kweziqhumane Ze-Semiconductor
Enye yezindlela ezibaluleke kakhulu zokusebenzisa ama-crucible e-SiC kusezinqubweni zokukhula kwekristalu. Ekukhiqizweni kwama-substrate e-silicon carbide, i-powder ye-SiC ehlanzekile kakhulu ishiswa kuze kufike emazingeni okushisa aphezulu kakhulu, lapho i-sublimation kanye ne-recrystallization zenzeka khona ukuze kwakheke amakristalu angawodwa. Kuyo yonke le nqubo, i-crucible isebenza njengesakhiwo esiyinhloko sokuthwala, ihlinzeka ngendawo yokushisa elawulwayo esekela ukwakheka kwekristalu ngenkathi inciphisa izingozi zokungcola. Ikhwalithi ye-crucible ingathinta kakhulu ubuningi besici, ukufana kwekristalu, kanye nokukhiqizwa kwe-wafer.
Ngale kokukhula kwekristalu ye-SiC, izimbobo ze-silicon carbide zisetshenziswa kabanzi ekukhiqizweni kwama-semiconductor ahlanganisiwe, kufaka phakathi i-gallium nitride (GaN), i-aluminium nitride (AlN), nezinye izinto ezithuthukisiwe ezisetshenziswa kumadivayisi kagesi kanye ne-optoelectronic. Ukumelana kwazo okuhle kakhulu nezinqubo zamakhemikhali ezibolayo kanye nokushaqeka kokushisa kuzenza zifanelekele izinqubo ezahlukahlukene zesigaba sokushisa okuphezulu kanye nokuthuthwa komphunga ngokomzimba (PVT). Ngaphezu kwalokho,Izitsha ze-SiCZivame ukusetshenziswa ezinhlelweni zokuhwamuka, ukuhlanganiswa kwezinto ezisetshenziswa ekushiseni okuphezulu, kanye nokucubungula okukhethekile kwe-ceramic lapho ukulawulwa kokungcola kanye nokufana kokushisa kuyizidingo ezibalulekile.
Izinzuzo Zobunjiniyela Zeziqhumane Ze-SiC
Ngokombono wobunjiniyela, izinzuzo zezimbobo ze-silicon carbide zidlulela ngale kokumelana nokushisa okulula. Ukushisa kwazo okuphezulu kusiza ukudala ukusatshalaliswa kokushisa okufanayo kulo lonke igumbi lenqubo, kunciphisa ama-gradient okushisa angabangela amaphutha ekristalu noma ukungahambisani kwezinto. Ukuqina kwazo okumangalisayo kwamakhemikhali kunciphisa ukusabela okungafuneki phakathi kwezinto ezimbobo kanye nezinto ezimbobo, kusiza ukugcina amazinga okuhlanzeka okuphezulu kakhulu adingekayo ekukhiqizweni kwe-semiconductor yesimanje. Ngaphezu kwalokho, amandla omshini angokwemvelo e-SiC asekela impilo yesevisi ende, ngisho nangaphansi kwezimo zokujikeleza kokushisa okuphindaphindiwe, okufaka isandla ekwehliseni izindleko zokulungisa kanye nokusebenza kahle kokukhiqiza okuthuthukisiwe.
Izinto Okufanele Uzicabangele Lapho Usebenzisa Ama-SiC Crucibles
Naphezu kwalezi zinzuzo, izitsha zokubhaka ze-silicon carbide azinazo izinselele. Njengezinye izitsha zokubhaka ze-ceramic ezithuthukisiwe, i-SiC ibonisa izinga lokuphuka futhi idinga ukuphathwa ngokucophelela ngesikhathi sokuthutha, ukufakwa, kanye nokugcinwa. Ukuchayeka ekujikelezeni kokushisa isikhathi eside kungagcina kubangele imifantu emincane noma ukuwohloka kwendawo, ikakhulukazi ezindaweni zokukhiqiza ezidinga kakhulu. Onjiniyela bezinqubo kumele futhi banake kakhulu ukwakheka kwezitsha zokubhaka, amazinga okuhlanzeka, kanye nokubekezelelana kobukhulu, njengoba lezi zici zingathinta kakhulu ukuphathwa kokushisa kanye nokusebenza kokukhula kwekristalu. Ukuhlolwa okuvamile kanye nokugcinwa kokuvimbela kuhlala kubalulekile ekwandiseni impilo yesevisi kanye nokugcina ukuhambisana kwenqubo.
Kungani Ukhethe Udokotela Wezilwane
Njengoba isidingo somhlaba wonke samadivayisi kagesi e-SiC kanye nezinto ze-semiconductor ezithuthukisiwe siqhubeka nokukhula, abakhiqizi badinga izixazululo eziqinile ezikwazi ukusekela ubukhulu obukhulu bekristalu, amafasitela enqubo aqinile, kanye nezinhloso zokukhiqiza eziphakeme. Yilapho i-VET Energy inikeza khona inani elibalulekile kubakhiqizi bemishini ye-semiconductor, abalimi bekristalu, kanye nabakhiqizi bezinto ezithuthukisiwe emhlabeni jikelele.
I-VET Energy igxile ekuthuthukisweni nasekukhiqizweni kwemishini esebenza kahle kakhului-silicon carbide kanye nezingxenye ze-ceramic ezithuthukisiwekwezicelo ze-semiconductor kanye nezamandla. Isebenzisa ubuchwepheshe obubanzi bezinto zokwakha, ubuchwepheshe bokukhiqiza obuthuthukisiwe, kanye nezinhlelo zokulawula ikhwalithi eziqinile, i-VET Energy iletha izitsha ze-SiC eziklanyelwe ukuhlangabezana nezidingo ezidingekayo zokukhula kwekristalu, ukucubungula okushisa okuphezulu, kanye nezindawo zokukhiqiza ze-semiconductor ezithuthukisiwe. Le nkampani inikeza izixazululo ezenziwe ngokwezifiso ezenzelwe izimo ezithile zenqubo, isiza amakhasimende ukuthi athuthukise ukusebenza kokushisa, athuthukise ikhwalithi yekristalu, anciphise izingozi zokungcola, futhi andise isikhathi sokuphila kwezingxenye.
Ngokusungula izinto ezintsha okuqhubekayo kubunjiniyela bezinto ezibonakalayo kanye nokukhiqizwa okunembile, i-VET Energy isekela ukushintshela kwemboni ye-semiconductor kuya kubuchwepheshe be-electronics yamandla esizukulwane esilandelayo kanye nobuchwepheshe be-semiconductor obune-bandgap. Kungakhathaliseki ukuthi ukukhula kwekristalu ye-SiC, ukukhiqizwa kwe-compound semiconductor, noma ezinye izinhlelo zokusebenza ezishisa kakhulu, izixazululo ze-silicon carbide crucible ze-VET Energy zinikeza ukuthembeka, ubumsulwa, kanye nokusebenza okudingekayo ekukhiqizweni kwe-semiconductor yesimanje. I-VET Energy yamukela imibuzo yakho eyengeziwe nganoma yisiphi isikhathi.
