I-Semicera ihlinzeka ngezingubo ezikhethekile ze-tantalum carbide (TaC) zezingxenye ezihlukahlukene nabathwali.Inqubo yokugqoka ehamba phambili ye-Semicera yenza i-tantalum carbide (TaC) ikwazi ukufeza ukuhlanzeka okuphezulu, ukuzinza okuphezulu kwezinga lokushisa kanye nokubekezelelana kwamakhemikhali aphezulu, ukuthuthukisa ikhwalithi yomkhiqizo wamakristalu e-SIC/GAN kanye nezendlalelo ze-EPI (I-Graphite embozwe nge-TaC susceptor), kanye nokwelula impilo yezingxenye ezibalulekile ze-reactor. Ukusetshenziswa kwe-tantalum carbide TaC coating ukuxazulula inkinga enqenqemeni nokwenza ngcono ikhwalithi yokukhula kwekristalu, futhi i-Semicera iphumelele ekuxazululeni ubuchwepheshe be-tantalum carbide coating (CVD), yafinyelela ezingeni eliphezulu lamazwe ngamazwe.
I-Silicon carbide (SiC) iyinto ebalulekile esizukulwaneni sesithathu sama-semiconductors, kodwa izinga layo lokukhiqiza libe yisici esikhawulela ukukhula kwemboni. Ngemva kokuhlolwa okubanzi emalabhorethri e-Semicera, kutholakale ukuthi i-TaC efuthwe futhi efakwe i-sintered ayinakho ukuhlanzeka okudingekayo kanye nokufana. Ngokuphambene, inqubo ye-CVD iqinisekisa izinga lokuhlanzeka kwe-5 PPM nokufana okuhle kakhulu. Ukusetshenziswa kwe-CVD TaC kuthuthukisa kakhulu izinga lokukhiqiza lama-silicon carbide wafers. Siyazamukela izingxoxoI-TaC Coated Graphite Izindandatho Ezinezingxenye Ezintathu ukuze kuqhutshekwe nokunciphisa izindleko zamawafa e-SiC.
Ngemva kweminyaka yokuthuthuka, i-Semicera inqobe ubuchwepheshe beI-CVD TaCngemizamo ehlanganyelwe yomnyango we-R&D. Ukukhubazeka kulula ukwenzeka enqubweni yokukhula kwama-wafers e-SiC, kodwa ngemva kokusebenzisaI-TaC, umehluko ubalulekile. Ngezansi ukuqhathaniswa kwamawafa ane-TaC nangenayo, kanye nezingxenye ze-Simicera zokukhula kwekristalu eyodwa.
nge-TaC nangaphandle kwayo
Ngemva kokusebenzisa i-TaC (kwesokudla)
Ngaphezu kwalokho, i-Semicera'sImikhiqizo ehlanganiswe ne-TaCbonisa impilo yesevisi ende kanye nokumelana okukhulu nezinga lokushisa eliphezulu uma kuqhathaniswaIzingubo ze-SiC.Izilinganiso zaselabhorethri ziye zabonisa ukuthi yethuI-TaC coatingsingasebenza ngokuqhubekayo emazingeni okushisa afinyelela ku-2300 degrees Celsius isikhathi eside. Ngezansi kukhona izibonelo zamasampuli ethu:
