IiSemicera'sI-Silicon Carbide Epitaxyyenzelwe ukuhlangabezana neemfuno ezingqongqo zezicelo zangoku zesemiconductor. Ngokusebenzisa iindlela eziphucukileyo zokukhula kwe-epitaxial, siqinisekisa ukuba umaleko ngamnye we-silicon carbide ubonisa umgangatho obalaseleyo wekristale, ukufana, kunye nokuxinana kwesiphene. Ezi mpawu zibalulekile ekuphuhliseni amandla ombane asebenza kakhulu, apho ukusebenza kakuhle kunye nolawulo lobushushu kubaluleke kakhulu.
II-Silicon Carbide EpitaxyInkqubo kwi-Semicera ilungiselelwe ukuvelisa iileya ze-epitaxial ezinobunzima obuchanekileyo kunye nolawulo lwe-doping, ukuqinisekisa ukusebenza okufanayo kuluhlu lwezixhobo. Eli nqanaba lokuchaneka liyimfuneko kwizicelo kwizithuthi zombane, iinkqubo zamandla avuselelekayo, kunye nonxibelelwano oluphezulu, apho ukuthembeka nokusebenza kakuhle kubaluleke kakhulu.
Ngaphezu koko, iSemicera'sI-Silicon Carbide Epitaxyibonelela nge-conductivity eyongeziweyo ye-thermal kunye ne-voltage ephezulu yokuqhekeka, iyenza ibe lolona khetho lukhethwayo kwizixhobo ezisebenza phantsi kweemeko ezinzima. Ezi mpawu zinegalelo kubomi obude besixhobo kunye nokuphucula ukusebenza kakuhle kwenkqubo iyonke, ngakumbi kumandla aphezulu kunye neemeko zobushushu obuphezulu.
I-Semicera ikwabonelela ngeenketho zokwenza ngokwezifisoI-Silicon Carbide Epitaxy, ukuvumela izisombululo ezilungiselelweyo ezihlangabezana neemfuno ezithile zesixhobo. Kungakhathaliseki ukuba uphando okanye imveliso enkulu, iileya zethu ze-epitaxial zenzelwe ukuxhasa isizukulwana esilandelayo se-semiconductor innovations, eyenza uphuhliso lwezixhobo zombane ezinamandla ngakumbi, ezisebenzayo, nezithembekileyo.
Ngokudibanisa itekhnoloji yokusika kunye neenkqubo ezingqongqo zokulawula umgangatho, iSemicera iqinisekisa ukuba yethuI-Silicon Carbide Epitaxyiimveliso azihlangani kuphela kodwa zigqithise imigangatho yoshishino. Oku kuzibophelela ekugqweseni kwenza iileya zethu ze-epitaxial zibe sisiseko esifanelekileyo sezicelo eziphambili ze-semiconductor, zivula indlela yempumelelo kumbane we-elektroniki kunye ne-optoelectronics.
