Wāhanga Haurua Marama Karāwhite Panipani SiChe wāhanga matua e whakamahia ana i roto i ngā tukanga hanga semiconductor, inā koa mō ngā taputapu epitaxial SiC. Ka whakamahia e mātou tā mātou hangarau patent hei hanga i te wāhanga halfmoon me te tino parakore, te ōritetanga o te paninga me te roa o te ora ratonga pai rawa atu, tae atu ki te ātete matū me ngā āhuatanga pumau wera teitei.
Rauemi turanga: karāpeti parakore teitei
Ngā whakaritenga parakore:te ihirangi waro ≥99.99%, te ihirangi pungarehu ≤5ppm, kia kore ai he poke e puta hei whakapoke i te paparanga epitaxial i ngā pāmahana tiketike.
Ngā painga mahi:
Te kawe wera teitei:Ka eke te kawe wera i te pāmahana rūma ki te 150W/(m・K), e tata ana ki te taumata o te parahi, ā, ka taea te whakawhiti wera tere.
Tauwehenga whakawhanui iti:5×10-6/℃ (25-1000℃), e ōrite ana ki te paparanga silicon carbide (4.2×10-6/℃), te whakaiti i te ngatata o te paninga i puta mai i te ahotea wera.
Te tika o te tukatuka:Ka tutukihia te ātete ā-ahu o te ±0.05mm mā te miihini CNC hei whakarite i te hiri o te rūma.
Ngā tono rerekē o te CVD SiC me te CVD TaC
| Paninga | Tukanga | Whakataurite | Te tono noa |
| CVD-SiC | Pāmahana: 1000-1200℃ Pēhanga: 10-100 Torr | Pakeke HV2500, matotoru 50-100um, ātete pai ki te waikura (pūmau i raro i te 1600℃) | Ngā oumu epitaxial whānui, e tika ana mō ngā hau tuku iho pērā i te hauwai me te silane |
| CVD-TaC | Pāmahana: 1600-1800℃ Pēhanga: 1-10 Torr | Te pakeke HV3000, te matotoru 20-50um, he tino ātete ki te waikura (ka taea te tu atu ki ngā hau waikura pēnei i te HCl, NH₃, me ētahi atu) | Ngā taiao tino waikura (pērā i te taputapu epitaxy me te whakairo GaN), ngā tukanga motuhake rānei e hiahia ana ki ngā pāmahana tino teitei o te 2600°C |
Arotakenga kounga
Te matotoru o te paninga: te ine matotoru taiaho (tika ±1um) te tātaritanga whakawhiti-wāhanga SEM rānei.
Kaha here: whakamātautau rakuraku (kawenga nui > 50N) whakamātautau ultrasonic rānei (tere oro > 5000m/s).
Ātete waikura: te tere ngaronga papatipu (<0.1 mg/cm²・h) i whakamatautauria i roto i te hau HCl (5 vol%, 1600℃).
He kaihanga ngaio a VET Energy e arotahi ana ki te R&D me te hanga rauemi matatau teitei pēnei i te graphite, te silicon carbide, te quartz, me te maimoatanga rauemi pēnei i te paninga SiC, te paninga TaC, te paninga waro karāhe, te paninga waro pyrolytic, me ētahi atu. E whakamahia whānuitia ana ēnei hua i roto i te photovoltaic, te semiconductor, te pūngao hou, te metallurgy, me ētahi atu.
