I-Tantalum carbide (TaC) ihlanganiswe nokuhlanzeka okuphezulu, ukuzinza okuphezulu kwezinga lokushisa nokumelana namakhemikhali aphezulu

I-Tantalum carbide (i-TaC) ehlanganiswe nokuhlanzeka okuphezulu, izinga lokushisa eliphakeme elizinzile kanye nokumelana namakhemikhali aphezulu Isithombe esifakiwe

Incazelo emfushane:

I-TaC enamathela iyisizukulwane esisha sezinto ezimelana nokushisa okuphezulu, ezinokuqina okungcono kwezinga lokushisa kune-SiC, njenge-coating emelana nokugqwala, i-oxidation ukumelana ne-oxidation, ukugqoka okuqinile, ingasetshenziswa endaweni engaphezu kuka-2000 ℃, esetshenziswa kabanzi ku-aerospace ultra- izinga lokushisa eliphezulu izingxenye ezishisayo ekupheleni, isizukulwane sesithathu semiconductor single crystal ukukhula kanye nezinye izinkambu.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-Semicera Semicera ihlinzeka ngezingubo ezikhethekile ze-tantalum carbide (TaC) zezingxenye ezihlukahlukene nabathwali.Inqubo yokugqoka ehamba phambili ye-Semicera 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 nezingqimba 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 Semicera iphumelele ekuxazululeni ubuchwepheshe be-tantalum carbide coating (CVD), yafinyelela ezingeni eliphezulu lamazwe ngamazwe.

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 zikaSimicera zokukhula kwekristalu eyodwa.

Ingxenye ye-Tac yokukhula kwekristalu eyodwa

Ngemva kokusebenzisa i-TaC (kwesokudla)

Ukwengeza, impilo yesevisi yemikhiqizo yokumboza ye-TaC ye-Semicera yinde futhi imelana kakhulu nezinga lokushisa eliphezulu kunaleyo yokunamathela kwe-SiC.Ngemva kwesikhathi eside sedatha yokulinganisa ilabhorethri, i-TaC yethu ingasebenza isikhathi eside ezingeni eliphakeme lika-2300 degrees Celsius.Alandelayo amanye amasampula ethu:
