I-Semicera ibonelela ngeengubo ezikhethekileyo ze-tantalum carbide (TaC) kumacandelo ahlukeneyo kunye nabathwali.Inkqubo ehamba phambili yokugqoka i-Semicera yenza iingubo ze-tantalum carbide (TaC) zifezekise ukucoceka okuphezulu, ukuzinza kweqondo lokushisa eliphezulu kunye nokunyamezela kweekhemikhali eziphezulu, ukuphucula umgangatho wemveliso ye-crystals ye-SIC / GAN kunye neengqimba ze-EPI (Isixhasi seTaC esigqunywe ngegraphite), kunye nokwandisa ubomi bamacandelo angundoqo we-reactor. Ukusetyenziswa kwetantalum carbide TaC coating kukusombulula ingxaki edge kunye nokuphucula umgangatho wokukhula kwekristale, kwaye iSemicera iye yasombulula itekhnoloji ye-tantalum carbide coating (CVD), ifikelele kwinqanaba eliphezulu lamazwe ngamazwe.
Ngokufika kwe-8-intshi ye-silicon carbide (SiC) wafers, iimfuno zeenkqubo ezahlukeneyo ze-semiconductor ziye zaqina ngakumbi, ngakumbi kwiinkqubo ze-epitaxy apho amaqondo okushisa angadlula i-2000 degrees Celsius. Izinto eziqhelekileyo ze-susceptor, ezifana ne-graphite ehlanganiswe ne-silicon carbide, ithande ukuzithoba kula maqondo obushushu aphezulu, ukuphazamisa inkqubo ye-epitaxy. Nangona kunjalo, i-CVD tantalum carbide (TaC) iwujonga kakuhle lo mba, imelana namaqondo obushushu ukuya kuma 2300 degrees Celsius kwaye inika ubomi benkonzo obude. Qhagamshelana neSemicera's Isixhobo sokugquma i-TaCukujonga ngakumbi malunga nezisombululo zethu eziphambili.
Emva kweminyaka yophuhliso, iSemicera yoyisile iteknoloji yeCVD TaCngeenzame ezidibeneyo zesebe leR&D. Iziphene kulula ukwenzeka kwinkqubo yokukhula kwee-wafers ze-SiC, kodwa emva kokusetyenziswaI-TaC, umahluko ubalulekile. Apha ngezantsi luthelekiso lweewafers ezine-TaC nangaphandle kwayo, kunye neendawo zeSimicera zokukhula kwekristale enye.
kunye nangaphandle kwe-TaC
Emva kokusebenzisa i-TaC (ekunene)
Ngaphezu koko, iSemicera'sIimveliso ezigqunywe yi-TaCbonisa ubomi benkonzo obude kunye nokumelana nobushushu obuphezulu xa kuthelekiswaIingubo zeSiC.Imilinganiselo yeLabhoratri ibonise ukuba yethuIingubo ze-TaCiyakwazi ukusebenza rhoqo kumaqondo obushushu ukuya kuma 2300 degrees Celsius ixesha elide. Ngezantsi yimizekelo yeesampulu zethu:
