Cov yam ntxwv

Koj Xaiv Silicon Carbide Wafers & SiC Substrates Li Cas?

Thaum xaiv silicon carbide (SiC) wafers thiab substrates, muaj ntau yam uas yuav tsum xav txog. Nov yog qee cov qauv tseem ceeb:

Hom Khoom Siv: Txheeb xyuas hom khoom siv SiC uas haum rau koj daim ntawv thov, xws li 4H-SiC lossis 6H-SiC. Cov qauv siv lead ua feem ntau yog 4H-SiC.

Hom Doping: Txiav txim siab seb koj puas xav tau ib lub substrate SiC uas muaj doped lossis undoped. Cov hom doping feem ntau yog N-hom (n-doped) lossis P-hom (p-doped), nyob ntawm koj cov kev xav tau tshwj xeeb.

Qhov Zoo ntawm Crystal: Soj ntsuam qhov zoo ntawm cov SiC wafers lossis substrates. Qhov zoo uas xav tau yog txiav txim siab los ntawm cov kev ntsuas xws li tus lej ntawm cov qhov tsis zoo, kev taw qhia crystallographic, thiab qhov roughness ntawm qhov chaw.

Txoj Kab Uas Siv Tau: Xaiv qhov loj ntawm lub wafer uas haum rau koj daim ntawv thov. Qhov loj feem ntau suav nrog 2 nti, 3 nti, 4 nti, thiab 6 nti. Qhov loj dua ntawm txoj kab uas siv tau, qhov ntau dua koj tuaj yeem tau txais ib lub wafer.

Qhov tuab: Xav txog qhov tuab ntawm SiC wafers lossis substrates. Cov kev xaiv tuab ib txwm muaj txij li ob peb micrometers mus txog ntau pua micrometers.

Kev Taw Qhia: Txheeb xyuas qhov kev taw qhia crystallographic uas phim nrog koj daim ntawv thov cov kev xav tau. Cov kev taw qhia feem ntau suav nrog (0001) rau 4H-SiC thiab (0001) lossis (0001̅) rau 6H-SiC.

Kev Tiav Ntawm Qhov Chaw: Soj ntsuam qhov tiav ntawm qhov chaw ntawm SiC wafers lossis substrates. Qhov chaw yuav tsum du, ci ntsa iab, thiab tsis muaj khawb lossis cov khoom qias neeg.

Lub Koob Npe ntawm Tus Muag Khoom: Xaiv tus neeg muag khoom uas muaj koob npe nrov uas muaj kev paub dhau los hauv kev tsim cov SiC wafers thiab cov substrates zoo. Xav txog cov yam xws li kev muaj peev xwm tsim khoom, kev tswj xyuas zoo, thiab kev tshuaj xyuas ntawm cov neeg siv khoom.

Tus nqi: Xav txog cov nqi cuam tshuam, suav nrog tus nqi rau ib lub wafer lossis substrate thiab lwm yam kev siv nyiaj ntxiv rau kev hloov kho.

Nws yog ib qho tseem ceeb uas yuav tsum tau soj ntsuam cov yam no kom zoo zoo thiab sab laj nrog cov kws tshaj lij lossis cov neeg muag khoom hauv kev lag luam kom ntseeg tau tias cov SiC wafers thiab cov substrates xaiv tau raws li koj cov kev xav tau tshwj xeeb.
