I-Semicera's 6 Inch Semi-Insulating HPSI SiC Wafers ziyilelwe ukuhlangabezana neemfuno eziqatha zobuchwepheshe bale mihla besemiconductor. Ngokucoceka okukhethekileyo kunye nokungaguquguquki, la mawafa asebenza njengesiseko esithembekileyo sokuphuhlisa amacandelo aphezulu e-elektroniki.
Ezi ziqwenga ze-HPSI SiC ziyaziwa ngokugqithiswa kwazo kwe-thermal kunye nokugquma kombane, ezibaluleke kakhulu ekuphuculeni ukusebenza kwezixhobo zamandla kunye neesekethe eziphezulu ze-frequency. Iimpawu ze-semi-insulating zinceda ekunciphiseni ukuphazamiseka kombane kunye nokwandisa ukusebenza kakuhle kwesixhobo.
Inkqubo yokwenziwa kwekhwalithi ephezulu eqeshwe yiSemicera iqinisekisa ukuba i-wafer nganye inobunzima obufanayo kunye neziphene ezincinci. Oku kuchanekileyo kubalulekile kwizicelo eziphambili ezifana nezixhobo zerediyo, ii-inverters zamandla, kunye neenkqubo ze-LED, apho ukusebenza kunye nokuqina zizinto eziphambili.
Ngokusebenzisa iindlela zokuvelisa ezikumgangatho ophezulu, iSemicera ibonelela ngeewafers ezingahlangani kuphela kodwa zigqithise imigangatho yoshishino. Ubungakanani be-intshi ye-6 inikezela ukuguquguquka ekunyuseni imveliso, ukulungiselela zombini uphando kunye nezicelo zorhwebo kwicandelo le-semiconductor.
Ukukhetha iSemicera's 6 Inch Semi-Insulating HPSI SiC Wafers kuthetha ukutyala imali kwimveliso enikezela ngomgangatho kunye nokusebenza okungaguqukiyo. La mawafa ayinxalenye yokuzibophelela kweSemicera ekuqhubeleni phambili izakhono zetekhnoloji ye-semiconductor ngokusebenzisa imathiriyeli entsha kunye nobuchule bobugcisa.
