I-Wafer ye-SOI ye-Semicera (i-Silicon kwi-Insulator) yenzelwe ukuhambisa ukohlula kombane okuphezulu kunye nokusebenza kwe-thermal. Olu lwakhiwo lwe-wafer lusungulayo, lunomaleko wesilicon kumaleko wokugquma, luqinisekisa ukusebenza okuphuculweyo kwesixhobo kunye nokuncipha kokusetyenziswa kwamandla, oko kusenza ukuba silungele usetyenziso oluhlukeneyo lobuchwepheshe obuphezulu.
Ii-wafers zethu ze-SOI zibonelela ngeenzuzo ezikhethekileyo kwiisekethe ezidibeneyo ngokunciphisa amandla e-parasitic kunye nokuphucula isantya kunye nokusebenza kakuhle kwesixhobo. Oku kubalulekile kwii-electronics zanamhlanje, apho ukusebenza okuphezulu kunye nokusebenza kakuhle kwamandla kubaluleke kakhulu kubathengi nakwimizi-mveliso.
I-Semicera isebenzisa ubuchule obuphambili bokuvelisa ukuvelisa ii-wafers ze-SOI ezinomgangatho ongaguqukiyo kunye nokuthembeka. Ezi wafers zibonelela ngokugqwesileyo kokugquma kwe-thermal, zizenza zilungele ukusetyenziswa kwindawo apho ukutshatyalaliswa kobushushu kuyinkxalabo, njengakwizixhobo zombane ezixinana kakhulu kunye neenkqubo zolawulo lwamandla.
Ukusetyenziswa kwee-wafers ze-SOI kwi-semiconductor fabrication ivumela ukuphuhliswa kweechips ezincinci, ezikhawulezayo kunye nezithembekileyo. Ukuzibophelela kweSemicera kubunjineli obuchanekileyo kuqinisekisa ukuba ii-wafers zethu ze-SOI ziyahlangabezana nemigangatho ephezulu efunekayo kubuchwephesha obukwinqanaba eliphezulu kwiinkalo ezifana nezonxibelelwano, iimoto, kunye nombane wabathengi.
Ukukhetha i-SOI Wafer ye-Semicera ithetha ukutyala imali kwimveliso exhasa ukuqhubela phambili kobuchwepheshe be-elektroniki kunye ne-microelectronic. Ii-wafers zethu ziyilelwe ukubonelela ukusebenza okuphuculweyo kunye nokuqina, igalelo kwimpumelelo yeeprojekthi zakho zobuchwepheshe obuphezulu kunye nokuqinisekisa ukuba uhlala uphambili ekuveliseni izinto ezintsha.
