Ko te MOCVD (Metal-Organic Chemical Vapor Deposition) he tikanga e whakamahia whānuitia ana mō te whakatakotoranga kiriata angiangi kounga teitei, ā, he mahi nui tana i roto i ngā ahumahi hanga semiconductor me te hikohiko. Hei wāhanga matua i roto i te tukanga MOCVD, ka whakamahia ngā whakamahana kua pania ki te SiC hei tautoko i ngā tauhohenga hau pāmahana teitei me te tipu o te wafer. I roto i tēnei taiao, ko te tono o ngā paninga silicon carbide (SiC) ka whakanui ake i te ātete o te whakamahana ki ngā pāmahana teitei, te waikura, me te waikura matū, he mea nui hei pupuri i te mahi pumau i te wā roa o te mahi.
Ko tētahi o ngā painga matua oNgā whakamahana kua pania ki te MOCVD SiCKo tōna kaha ki te kawe wera me te pāmahana teitei te mea nui, e āhei ai rātou ki te mahi pono i raro i ngā āhuatanga tino kino. He tino teitei te ira rewa o te silicon carbide, e āhei ai te noho pumau o te hanganga i ngā pāmahana teitei, me te ārai i te whakarerekētanga, te pakaru rānei ka puta mai i ngā huānga whakamahana tikanga. Hei tāpiri, ko te pumau matū teitei o ngā paninga SiC ka āhei te ātete whai hua ki te whānuitanga o ngā taiao waikura, e whakarite ana i te roa o te ora ratonga me te whakaiti i ngā whakaritenga tiaki.
I roto i ngā pūnaha MOCVD, ko te huihuinga whakamahana te mea tika hei whakatau i te pumau o te pāmahana i roto i te rūma tauhohenga me te ōritetanga o te whakatakotoranga. He mahi nui tā ngā whakamahana kua pania ki te SiC i roto i tēnei mahi nui. Ko te nuinga o ēnei whakamahana he mea hanga ki te karāhe parakore teitei, ki ngā papa waro motuhake rānei, me te paparanga SiC matotoru me te ōrite e whakatakotoria ana ki te mata mā te whakatakotoranga kohu matū, e whakapai ake ana i te kaha miihini me te mahi rauemi.
Haunga te ātete ki te pāmahana teitei, ka tukuna hoki e ngā paninga SiC he painga mārama ki te whakahaere matūriki. I te wā e tipu ana te MOCVD, ahakoa he iti noa te parahanga matūriki ka pā kino ki te kounga o te paparanga epitaxial. Ka pehia e te mata SiC matotoru te pirau o te papa me te mimiti o te rauemi, ka whakaiti i te whakaputanga matūriki me te whakatutuki i ngā whakaritenga horoi me te hua o te hanga semiconductor matū. He mea nui tēnei āhuatanga i roto i ngā tono epitaxial matatau e uru ana ki te GaN me te SiC.
I raro i te whakamahinga pāmahana teitei mō te wā roa, ko te pumau o te huringa wera tētahi atu tohu mahi matua mō ngā whakamahana. He iti te tauwehenga whānui wera o ngā paninga SiC, ā, he kaha te ātete ki te ru wera, e whakaiti ana i te tūponotanga o te ngatata, te wehewehe rānei i ngā huringa whakamahana me te whakamatao. Ka āwhina tēnei pumau ki te pupuri i te ātete hiko me te whai huatanga o te whakamahana, e whakaiti ana i te nekenekehanga o te tukanga, me te whakarato i tētahi matapihi tukanga e taea ai te whakahaere mō te whakaputa papatipu.
Mai i te tirohanga tiaki, he roa ake te ora o ngā whakamahana kua pania ki te SiC MOCVD ki te whakataurite ki ngā otinga uku kāore i pania, ki ngā otinga uku rerekē rānei. Nā te ātete pai ki te waikura ka taea e rātou te tu atu ki ngā hau matū me ngā hua tauhohenga, ka whakaiti i te auau horoi me ngā wā whakakapinga, ka whakaiti i te wā kore mahi o ngā taputapu, ā, ka whai wāhi ki te pikinga ake o te hua whakaputa katoa.
I te haere tonu o ngā hangarau haurua-ā-irahiko matū ki te anga whakamua ki ngā mātotoru mana teitei ake me ngā rahi wafer nui ake, ka piki ake te tono mō te ōritetanga o te pāmahana whakamahana me te pono mō te wā roa. Me ngā tukanga paninga kua pakeke me ngā āhuatanga rauemi pumau,Ngā whakamahana kua pania ki te MOCVD SiCkua whānuitia te whakamahi i ngā wāhanga matua o ngā taputapu epitaxial teitei, e whakarato ana i te tautoko pakari mō ngā tukanga tipu epitaxial matatau.
