Uzikhetha njani iiSilicon Carbide Wafers & SiC Substrates?

Xa ukhetha isilicon carbide (SiC) wafers kunye substrates, kukho izinto ezininzi ekufuneka ziqwalaselwe. Nazi ezinye iinqobo ezibalulekileyo:

Uhlobo lwezinto eziphathekayo: Qinisekisa uhlobo lwezinto ze-SiC ezihambelana nesicelo sakho, njenge-4H-SiC okanye i-6H-SiC. Isakhiwo sekristale esisetyenziswa ngokuqhelekileyo yi-4H-SiC.

Uhlobo lweDoping: Gqiba ukuba ufuna i-substrate ye-SiC ene-doped okanye engafakwanga. Iintlobo ze-doping eziqhelekileyo ziyi-N-type (n-doped) okanye i-P-type (p-doped), kuxhomekeke kwiimfuno zakho ezithile.

Umgangatho weCrystal: Vavanya umgangatho wekristale weewafers zeSiC okanye ii-substrates. Umgangatho ofunekayo umiselwa iiparamitha ezifana nenani leziphene, ukuqhelaniswa nekristale, kunye noburhabaxa bomphezulu.

I-Wafer Diameter: Khetha ubungakanani bewafer obufanelekileyo ngokusekwe kwisicelo sakho. Ubukhulu obuqhelekileyo bubandakanya i-intshi ezi-2, i-intshi ezi-3, i-intshi ezi-4, kunye ne-intshi ezi-6. Ubukhulu bedayamitha, kokukhona unokusifumana isivuno esisicaba.

Ukutyeba: Qwalasela ubukhulu obufunwayo beewafa zeSiC okanye iisubstrates. Iinketho zokutyeba eziqhelekileyo zisusela kwiimicrometer ezimbalwa ukuya kumakhulu aliqela eemicrometer.

Ukuqhelaniswa: Misela ikristallographic orientation ehambelana neemfuno zesicelo sakho. Uqhelaniso oluqhelekileyo lubandakanya (0001) kwi-4H-SiC kunye (0001) okanye (0001̅) ye-6H-SiC.

Ukugqitywa komphezulu: Vavanya ukugqitywa komphezulu wee-wafers ze-SiC okanye ii-substrates. Umphezulu kufuneka ugudiswe, ukhazimliswe, kwaye ungabi nemikrwelo okanye ungcoliseko.

Udumo loMboneleli: Khetha umboneleli othembekileyo onamava abanzi ekuveliseni iiwafers zeSiC ezikumgangatho ophezulu kunye nee substrates. Qwalasela izinto ezifana nesakhono sokwenza, ulawulo lomgangatho, kunye nophononongo lwabathengi.

Iindleko: Qwalasela iindleko, kubandakanywa ixabiso lewafer nganye okanye i-substrate kunye naziphi na iindleko ezongezelelweyo zokulungisa.

Kubalulekile ukuvavanya ngononophelo le miba kwaye udibane neengcali zoshishino okanye ababoneleli ukuqinisekisa ukuba ii-wafers ze-SiC ezikhethiweyo kunye ne-substrates ziyahlangabezana neemfuno zakho zesicelo.
