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.
Ngokufika kwama-wafers angu-8-inch silicon carbide (SiC), izidingo zezinqubo ezihlukahlukene ze-semiconductor ziye zaqina kakhulu, ikakhulukazi ezinqubweni ze-epitaxy lapho amazinga okushisa angadlula ama-degree Celsius angu-2000. Izinto zendabuko ezibamba ukushisa, njenge-graphite eboshwe nge-silicon carbide, zivamise ukuzithoba kulawa mazinga okushisa aphezulu, ziphazamise inqubo ye-epitaxy. Kodwa-ke, i-CVD tantalum carbide (TaC) ibhekana ngempumelelo nalolu daba, imelana namazinga okushisa afika ku-2300 degrees Celsius futhi inikeza impilo yesevisi ende. Xhumana ne-Semicera's I-TaC coating susceptorukuze uhlole kabanzi mayelana nezixazululo zethu ezithuthukile.
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:
