Whakataki oKarāpire Hiraka
Ko te mātotoru o te silicon carbide (SIC) he 3.2g/cm3. He tino onge te silicon carbide tūturu, ā, ka hangaia mā te tikanga horihori. E ai ki ngā momo whakarōpūtanga rerekē o te hanganga tioata, ka taea te wehewehe i te silicon carbide ki ngā wāhanga e rua: α SiC me β SiC. Ko te semiconductor o te whakatupuranga tuatoru e tohuhia ana e te silicon carbide (SIC) he auau teitei, he pai te mahi, he kaha teitei, he ātete ki te pēhanga teitei, he ātete ki te pāmahana teitei me te ātete kaha ki te hihi. He pai mō ngā hiahia rautaki nui o te tiaki pūngao me te whakaiti i ngā tukunga, te hanga atamai me te haumarutanga mōhiohio. Hei tautoko i te auahatanga motuhake me te whanaketanga me te whakawhiti o te whakawhitiwhiti waea pūkoro o te whakatupuranga hou, ngā waka pūngao hou, ngā tereina tereina tereina, te Ipurangi pūngao me ētahi atu ahumahi. Ko ngā rauemi matua me ngā wāhanga hiko kua whakahoutia kua noho hei arotahi mō te hangarau semiconductor o te ao me te whakataetae ahumahi. I te tau 2020, kei roto te tauira ōhanga me te tauhokohoko o te ao i te wā whakahou, ā, he uaua ake, he kino ake te taiao o roto me waho o te ōhanga o Haina, engari kei te tipu haere te umanga semiconductor o te whakatupuranga tuatoru o te ao i te taha o te ia. Me mōhio kua uru te umanga silicon carbide ki tētahi wāhanga whanaketanga hou.

Ko te tono o te silicon carbide i roto i te umanga semiconductor ko te mekameka umanga semiconductor silicon carbide te nuinga o te paura silicon carbide parakore teitei, te papa tioata kotahi, te epitaxial, te taputapu hiko, te takai kōwae me te tono tauranga, me ētahi atu.
1. Ko te papa tioata kotahi te rauemi tautoko, te rauemi kawe me te papa tipu epitaxial o te semiconductor. I tēnei wā, ko ngā tikanga tipu o te tioata kotahi SiC ko te whakawhiti hau ā-tinana (PVT), te wāhanga wai (LPE), te whakatakotoranga kohu matū pāmahana teitei (htcvd) me ētahi atu. 2. Ko te pepa epitaxial silicon carbide epitaxial e pā ana ki te tipu o te kiriata tioata kotahi (paparanga epitaxial) me ētahi whakaritenga me te aronga rite ki te papa. I roto i te tono mahi, ko ngā taputapu semiconductor āputa whānui kei runga i te paparanga epitaxial, ā, ko ngā maramara silicon carbide ka whakamahia anake hei papa, tae atu ki ngā paparanga epitaxial Gan.
3. te parakore teiteiSiCHe rauemi mata te paura mō te whakatipu i te karaihe kotahi silicon carbide mā te tikanga PVT. Ka pā tika te parakore o te hua ki te kounga tipu me ngā āhuatanga hiko o te karaihe kotahi SiC.
4. He mea hanga te taputapu hiko ki te silicon carbide, he ātete pāmahana teitei, he auau teitei, he pai hoki te mahi. E ai ki te āhua mahi o te taputapu,SiCKo ngā taputapu mana ko ngā diode mana me ngā ngongo pana mana.
5. I roto i te tono haurua-ā-whakatupuranga tuatoru, ko ngā painga o te tono whakamutunga ko te taea e rātou te tāpiri i te haurua-ā-whakatupuranga GaN. Nā te pai o te huringa nui, ngā āhuatanga whakamahana iti me te mama o ngā taputapu SiC, kei te piki haere tonu te tono o te umanga o raro, ā, kei te whai i te au o te whakakapi i ngā taputapu SiO2. Kei te whanake tonu te āhua o te whanaketanga o te mākete silicon carbide i tēnei wā. Ko te silicon carbide te kaiārahi i te tono whanaketanga haurua-ā-whakatupuranga tuatoru. Kua tere ake te urunga mai o ngā hua haurua-ā-whakatupuranga tuatoru, kei te whānui haere tonu ngā mara tono, ā, kei te tere tipu te mākete me te whanaketanga o ngā hiko motuka, te whakawhitiwhiti kōrero 5g, te tuku hiko utu tere me te tono hōia.
