Khoom duab
Silicon Carbide (SiC) wafers yog ib hom khoom siv semiconductor siv los tsim cov khoom siv hluav taws xob thiab optoelectronic uas yuav tsum muaj qhov kub thiab txias, high-voltage, thiab kev ua haujlwm siab. SiC yog cov khoom siv dav-bandgap semiconductor, uas txhais tau hais tias nws muaj qhov tawg ntau dua thiab tuaj yeem ua haujlwm ntawm qhov kub siab dua li cov khoom siv semiconductors xws li silicon.
SiC wafers feem ntau yog tsim los ntawm kev siv lub cev vapor thauj (PVT) lossis tshuaj vapor deposition (CVD) txoj kev. Hauv PVT txoj kev, cov noob siv lead ua ntawm SiC tau muab tso rau hauv qhov cub kub kub thiab cov khoom siv, feem ntau silicon lossis carbon, yog cua sov kom txog thaum nws vaporizes. Cov vapor yog thauj los ntawm cov cab kuj roj, feem ntau argon, thiab tso rau ntawm cov noob siv lead ua, tsim ib txheej siv lead ua SiC. Hauv CVD txoj kev, SiC txheej yog tso rau ntawm lub substrate los ntawm reacting cov roj sib tov uas muaj silicon thiab carbon precursors ntawm qhov kub thiab txias.
Thaum SiC siv lead ua loj hlob tuaj, nws raug txiav rau hauv nyias wafers thiab polished mus rau qib siab ntawm flatness thiab smoothness. Qhov tshwm sim SiC wafers tuaj yeem siv los ua lub platform rau kev loj hlob ntawm cov txheej txheem semiconductor ntxiv, uas tuaj yeem doped nrog impurities los tsim p-hom thiab n-hom cheeb tsam rau kev tsim khoom.
SiC wafers muaj ntau qhov zoo dua lwm cov khoom siv semiconductor xws li silicon. SiC muaj cov thermal conductivity ntau dua, uas txhais tau hais tias nws tuaj yeem ua haujlwm ntawm qhov kub siab dua yam tsis muaj kev cuam tshuam los ntawm thermal tawg. Tsis tas li ntawd, SiC muaj lub zog tawg ntau dua thiab tuaj yeem ua haujlwm ntawm cov hluav taws xob ntau dua thiab cov zaus ntau dua li silicon, ua rau nws tsim nyog rau kev siv xws li hluav taws xob hluav taws xob thiab cov khoom siv hluav taws xob siab.
Sib sib zog nqus khawb rau hauv SiC Wafers Properties
Cov qauv hluav taws xob tshwj xeeb ntawm SiC wafers yog tus yuam sij rau lawv cov khoom tshwj xeeb. Lub dav bandgap tsim ib qho teeb meem siab rau electrons kom kov yeej, ua rau ob qho txiaj ntsig tseem ceeb:
Kev kub ntxhov siab:Tsawg cov neeg nqa khoom nruab nrab qis txhais tau tias SiC cov cuab yeej tuaj yeem ua haujlwm ntawm qhov kub siab yam tsis muaj qhov cuam tshuam loj, zoo tagnrho rau qhov xav tau ib puag ncig.
High Breakdown Electric Field:Qhov dav bandgap kuj tseem ua rau muaj peev xwm tiv taus cov hluav taws xob siab, tso cai rau cov khoom siv nrog cov hluav taws xob thaiv hluav taws xob siab thiab qis hauv xeev tsis kam.
Tshaj li cov khoom hluav taws xob, SiC wafers ua tau zoo hauv thermal thiab mechanical yam zoo li.
Efficient Thaum tshav kub kub Dissipation:Qhov tshwj xeeb thermal conductivity tso cai rau SiC kom tshem tawm cov cua sov, qhov tseem ceeb rau kev siv hluav taws xob siab.
Durability hauv Harsh Environments:Lub zog txhua yam thiab hardness ua rau SiC resistant rau hnav thiab tsim kua muag, haum rau xav tau ib puag ncig.
SiC los ntawm ntau hom hu ua polytypes, txawv los ntawm stacking kev npaj ntawm silicon thiab carbon atoms. Ntawm cov no, 4H-SiC thiab 6H-SiC yog qhov tseem ceeb tshaj plaws hauv hluav taws xob.
4 H-SiC:Txaus siab rau cov hluav taws xob hluav taws xob vim nws cov khoom siv hluav taws xob zoo tshaj plaws thiab dav bandgap, txhais kom ua tau zoo dua thiab ua haujlwm tau zoo.
6 H-SiC:Pom cov ntawv thov nyob rau hauv qhov kub thiab txias thiab cov khoom siv ntau zaus vim nws qhov siab dua qhov kev txav mus los thiab me ntsis nqaim bandgap.
Kev xaiv ntawm polytype hinges ntawm daim ntawv thov tshwj xeeb cov kev xav tau. Cov yam ntxwv xws li cov khoom siv hluav taws xob xav tau, kev ua haujlwm, thiab kev ua haujlwm ntawm cov cuab yeej siv tau ua lub luag haujlwm hauv kev xaiv hom SiC wafer zoo.
