SICOI (Silicon Carbide oo ku jira Insulator) Wafers SiC Film ON Silicon

Sharaxaad Gaaban:

Wafer-ka Silicon Carbide-ka ee Insulator-ka (SICOI) waa substrate-ka jiilka xiga ee semiconductor-ka kaas oo isku daraya sifooyinka sare ee jireed iyo elektaroonik ee silicon carbide (SiC) oo leh astaamaha go'doominta korantada ee heerka sare ee lakabka dahaarka leh, sida silicon dioxide (SiO₂) ama silicon nitride (Si₃N₄). Wafer-ka SICOI ee caadiga ah wuxuu ka kooban yahay lakab khafiif ah oo SiC ah, filim dahaar dhexdhexaad ah, iyo substrate saldhig taageero ah, kaas oo noqon kara silicon ama SiC.
