Tam sim no, peb lub tuam txhab tuaj yeem muab cov khoom me me ntawm 8inchN hom SiC wafers, yog tias koj muaj cov qauv xav tau, thov hu rau kuv.Peb muaj qee cov qauv wafers npaj xa tuaj.
Nyob rau hauv lub tshav pob ntawm cov ntaub ntawv semiconductor, lub tuam txhab tau ua ib tug loj breakthrough nyob rau hauv kev tshawb fawb thiab kev loj hlob ntawm loj loj SiC crystals.Los ntawm kev siv nws tus kheej cov noob muaju tom qab ntau lub voj voog ntawm txoj kab uas hla, lub tuam txhab tau ua tiav 8-nti N-hom SiC crystals, uas daws cov teeb meem nyuaj xws li qhov kub tsis sib xws, siv lead ua tawg thiab roj theem raw khoom faib rau hauv cov txheej txheem kev loj hlob ntawm 8-nti SIC muaju, thiab ua kom muaj kev loj hlob ntawm cov loj loj SIC muaju thiab cov txheej txheem kev tswj hwm kev tswj hwm thiab tswj tau.Txhim kho lub tuam txhab kev sib tw tseem ceeb hauv SiC ib leeg siv lead ua substrate kev lag luam.Nyob rau tib lub sijhawm, lub tuam txhab nquag txhawb nqa kev sib sau ntawm cov thev naus laus zis thiab txheej txheem ntawm qhov loj me me silicon carbide substrate npaj kev sim kab, ntxiv dag zog rau kev sib pauv kev lag luam thiab kev lag luam kev sib koom tes hauv cov dej ntws thiab cov dej ntws, thiab koom tes nrog cov neeg siv khoom kom rov ua cov khoom lag luam tas li, thiab sib koom ua ke. txhawb txoj kev ua haujlwm ntawm kev siv cov khoom siv silicon carbide.
