SiC silicon carbideE pā ana te taputapu ki te taputapu i hangaia ki te silicon carbide hei rauemi mata.
E ai ki ngā āhuatanga ātete rerekē, ka wehea ki ngā taputapu hiko silicon carbide kawe mekarāhe silicon haurua-mātaoNgā taputapu RF.
Ngā āhua matua o te taputapu me ngā whakamahinga o te silicon carbide
Ko ngā painga matua o te SiC i runga iNgā rauemi Siko:
E toru ngā wā o te āputa roopu o te SiC i tō te Si, ā, ka taea e tēnei te whakaiti i te turuturu me te whakanui ake i te ātete pāmahana.
Ko te kaha o te mara pakaru o te SiC he 10 ngā wā te nui ake i te Si, ā, ka taea e ia te whakapai ake i te kiato o ia au, te auau whakahaere, te tu atu ki te kaha ngaohiko me te whakaiti i te ngaronga whakaweto-whakakā, he pai ake mō ngā tono ngaohiko teitei.
E rua ngā tere o te nekehanga kōkō irahiko o te SiC i tō te Si, nō reira ka taea te mahi i te auau teitei ake.
E toru ngā wā te nui ake o te kawe wera o te SiC i tō te Si, he pai ake te mahi tohatoha wera, ka taea te tautoko i te kiato mana teitei me te whakaiti i ngā whakaritenga tohatoha wera, ka māmā ake te taputapu.
Papa kawe
Papa kawe hiko: Mā te tango i ngā poke o roto i te karaihe, inā koa ngā poke papaku, kia tutuki ai te ātete teitei o roto o te karaihe.

Ko te taputapu hiko silicon carbide kawe hiko, mā te whakatipu i te paparanga epitaxial silicon carbide i runga i te papa kawe hiko, ka tukatukahia anō te pepa epitaxial silicon carbide, tae atu ki te hanga i ngā diode Schottky, MOSFET, IGBT, me ētahi atu, e whakamahia ana i roto i ngā waka hiko, te whakaputa hiko photovoltaic, te kawe tereina, te pokapū raraunga, te utu me ētahi atu hanganga. Ko ngā painga mahi penei:
Ngā āhuatanga pēhanga teitei kua whakarei ake. Ko te kaha o te papa hiko pakaru o te silicon carbide he neke atu i te 10 ngā wā i tō te silicon, ā, nā tēnei ka nui ake te ātete pēhanga teitei o ngā taputapu silicon carbide i tō ngā taputapu silicon ōrite.
He pai ake ngā āhuatanga pāmahana teitei. He nui ake te kawe wera o te silicon carbide i te silicon, e māmā ake ai te horapa wera o te taputapu, ā, e teitei ake ai te pāmahana whakahaere. Ka taea e te ātete pāmahana teitei te whakanui ake i te mātotoru mana, me te whakaiti i ngā whakaritenga mō te pūnaha whakamatao, kia māmā ake ai, kia iti ake ai te pūmau.
He iti ake te whakapaunga pūngao. ① He iti rawa te ātete-whakaū me te iti o te ngaronga-whakaū o te taputapu warowaihā hiko; (2) He iti ake te ia turuturu o ngā taputapu warowaihā hiko i ērā o ngā taputapu warowaihā hiko, ā, ka whakaitihia te ngaronga hiko; ③ Kāore he āhuatanga whakaweto iahiko i roto i te tukanga whakaweto o ngā taputapu warowaihā hiko, ā, he iti te ngaronga whakawhiti, e tino whakapai ake ana i te auau whakawhiti o ngā tono mahi.
Papa SiC haurua-whakamaroke: Ka whakamahia te tāpiringa N hei whakahaere tika i te ātete o ngā hua kawe mā te whakatikatika i te whanaungatanga e rite ana i waenga i te kukū tāpiringa hauota, te tere tipu me te ātete tioata.
Rauemi papa-haumaru-haurua teitei te parakore
Ka hangaia anō hoki ngā taputapu RF e hangai ana ki te waro silicon haurua-whakamaroke mā te whakatipu i te paparanga epitaxial gallium nitride ki runga i te paparanga silicon carbide haurua-whakamaroke hei whakarite i te pepa epitaxial silicon nitride, tae atu ki te HEMT me ētahi atu taputapu RF gallium nitride, e whakamahia whānuitia ana i roto i ngā whakawhitiwhiti kōrero 5G, ngā whakawhitiwhiti kōrero waka, ngā tono parepare, te tuku raraunga, me te rererangi.
Ko te tere o te nekenekehanga irahiko kua kōtuitia o ngā rauemi silicon carbide me te gallium nitride he 2.0 me te 2.5 ngā wā i te silicon, nō reira he nui ake te auau mahi o ngā taputapu silicon carbide me te gallium nitride i ērā o ngā taputapu silicon tuku iho. Heoi, ko te ngoikoretanga o te rauemi gallium nitride ko te ātete wera iti, ko te silicon carbide he ātete wera pai me te kawe wera, ka taea te whakakapi i te ātete wera iti o ngā taputapu gallium nitride, nō reira ka whakamahia e te umanga te silicon carbide haurua-whakamaroke hei papa, ā, ka whakatōkia te paparanga epitaxial gan ki runga i te papa silicon carbide hei hanga taputapu RF.
