3 nti SiC substrate Ntau Lawm Dia76.2mm 4H-N

Cov yam ntxwv tseem ceeb ntawm 3 nti silicon carbide mosfet wafers yog raws li nram no;

Silicon Carbide (SiC) yog ib yam khoom siv semiconductor dav dav, uas muaj cov thermal conductivity siab, electron mobility siab, thiab lub zog hluav taws xob tawg siab. Cov khoom no ua rau SiC wafers zoo tshaj plaws hauv kev siv hluav taws xob siab, zaus siab, thiab kub siab. Tshwj xeeb tshaj yog nyob rau hauv 4H-SiC polytype, nws cov qauv siv lead ua rau muaj kev ua tau zoo hauv hluav taws xob, ua rau nws yog cov khoom siv xaiv rau cov khoom siv hluav taws xob fais fab.

Lub wafer 3-nti Silicon Carbide 4H-N yog lub wafer uas muaj nitrogen-doped nrog N-hom conductivity. Txoj kev doping no ua rau lub wafer muaj electron concentration ntau dua, yog li ua kom lub cuab yeej ua haujlwm tau zoo dua. Qhov loj ntawm lub wafer, ntawm 3 nti (txoj kab uas hla ntawm 76.2 hli), yog qhov loj me uas siv ntau hauv kev lag luam semiconductor, tsim nyog rau ntau yam txheej txheem tsim khoom.

Lub wafer 3-nti Silicon Carbide 4H-N yog tsim los ntawm kev siv txoj kev Physical Vapor Transport (PVT). Cov txheej txheem no suav nrog kev hloov SiC hmoov mus rau hauv cov siv lead ua ke ntawm qhov kub siab, kom ntseeg tau tias cov siv lead ua zoo thiab sib xws ntawm lub wafer. Tsis tas li ntawd, lub wafer tuab feem ntau yog li 0.35 hli, thiab nws qhov chaw yog raug rau ob sab polishing kom ua tiav qib siab ntawm kev tiaj tus thiab du, uas yog qhov tseem ceeb rau cov txheej txheem tsim khoom semiconductor tom ntej.

Cov ntawv thov ntawm 3-nti Silicon Carbide 4H-N wafer yog dav heev, suav nrog cov khoom siv hluav taws xob muaj zog siab, cov ntsuas kub siab, cov khoom siv RF, thiab cov khoom siv optoelectronic. Nws qhov kev ua tau zoo thiab kev ntseeg siab ua rau cov khoom siv no ua haujlwm ruaj khov hauv qab qhov xwm txheej hnyav, ua tau raws li qhov xav tau rau cov khoom siv semiconductor ua tau zoo hauv kev lag luam hluav taws xob niaj hnub.

Peb tuaj yeem muab 4H-N 3 nti SiC substrate, ntau qib ntawm cov substrate stock wafers. Peb kuj tuaj yeem npaj kev hloov kho raws li koj xav tau. Txais tos nug!
