He aha te paninga silicon carbide?

Paninga karawiti silicon,E mōhiotia whānuitia ana ko te paninga SiC, e pā ana ki te tukanga o te paninga i tētahi paparanga o te silicon carbide ki runga i ngā mata mā roto i ngā tikanga pēnei i te Chemical Vapor Deposition (CVD), te Physical Vapor Deposition (PVD), te rehu wera rānei. Ka whakarei ake tēnei paninga uku silicon carbide i ngā āhuatanga mata o ngā momo papa mā te whakarato i te ātete kakahu tino pai, te pumau wera, me te tiaki i te waikura. E mōhiotia ana te SiC mō ōna āhuatanga ā-tinana me te matū tino pai, tae atu ki te ira rewa teitei (tata ki te 2700℃), te pakeke rawa (Mohs 9 tauine), te ātete waikura me te waikura tino pai, me te mahi whakawetiweti tino pai.

Ngā Painga Matua o te Paninga Silicon Carbide i roto i ngā Mahi Ahumahi

Nā ēnei āhuatanga, e whakamahia whānuitia ana te paninga silicon carbide i roto i ngā mara pēnei i te rererangi, ngā taputapu patu, me te tukatuka semiconductor. I roto i ngā taiao tino kino, inā koa i roto i te awhe 1800-2000℃, he tino pai te pumau o te paninga SiC ki te pāmahana me te ātete ki te tango, he mea tino pai mō ngā tono pāmahana teitei. Heoi, kāore i te silicon carbide anake te hanganga e hiahiatia ana mō ngā tono maha, nō reira ka whakamahia ngā tikanga paninga hei whakamahi i ōna āhuatanga ahurei me te kore e whakararu i te kaha o ngā wāhanga. I roto i te hanga semiconductor, ka whakaratohia e ngā huānga paninga silicon carbide he tiaki pono me te pumau mahi i roto i ngā taputapu e whakamahia ana i roto i ngā tukanga MOCVD.

Ngā Tikanga Noa mō te Whakarite Paninga Silicon Carbide

Ⅰ● Paninga Whakatakotoranga Kohu Matū (CVD) Silicon Carbide

I tēnei tikanga, ka hangaia ngā paninga SiC mā te whakanoho i ngā papa ki roto i tētahi rūma tauhohenga, ka mahi te methyltrichlorosilane (MTS) hei matū mua. I raro i ngā āhuatanga whakahaeretia—ko te tikanga he 950-1300°C me te pēhanga kino—ka pirau te MTS, ā, ka whakatakotoria te silicon carbide ki runga i te mata. Mā tēnei tukanga paninga CVD SiC ka whakarite he paninga matotoru, ōrite me te piri pai, he mea tino pai mō ngā tono tino tika i roto i ngā rāngai semiconductor me te rererangi.

Tuarua● Tikanga Whakawhitinga Tūmua (Whakakī me te Whakapūkara Polymer – PIP)

Ko tētahi atu huarahi whai hua mō te paninga rehu silicon carbide ko te tikanga huringa precursor, arā, ko te tuku i te tauira kua tukatukahia i mua ki roto i te otinga precursor uku. Whai muri i te whakakorekore i te tāke whakakī me te pēhanga i te paninga, ka whakamahanahia te tauira, ka hua ake he paninga silicon carbide i te wā e whakamatao ana. He pai ake tēnei tikanga mō ngā wāhanga e hiahia ana kia rite te matotoru o te paninga me te ātete ki te kakahu.

Ngā Āhuatanga Ā-tinana o te Paninga Silicon Carbide

He āhuatanga pai ngā paninga karawiti silicon e pai ai mō ngā tono ahumahi uaua. Kei roto i ēnei āhuatanga:

Te Arahi Wera: 120-270 W/m·K
Tauwehenga o te Whakawhanuitanga Wera: 4.3 × 10^^(-6)/K (i te 20~800℃)
Ātete Hiko: 10^⁵– 10^⁶Ω·cm
Pakari: Tauine Mohs 9

Ngā Whakamahinga o te Paninga Silicon Carbide

I roto i te hanga haurua-haurua, ka tiakina ngā taputapu nui e te paninga silicon carbide mō te MOCVD me ētahi atu tukanga pāmahana-tiketike, pērā i ngā tauhohenga me ngā kaiwhakaū, mā te tuku i te ātete pāmahana-tiketike me te pumau. I roto i te rererangi me te tiaki whenua, ka pania ngā paninga uku silicon carbide ki ngā wāhanga me tu atu ki ngā pānga tere-tiketike me ngā taiao waikura. Hei tāpiri, ka taea hoki te whakamahi i te peita silicon carbide, i ngā paninga rānei ki ngā taputapu hauora e hiahia ana kia roa te mau i raro i ngā tikanga whakahoromata.

He aha i whiriwhiri ai i te paninga Silicon Carbide?

Me te wheako kua whakamātauhia ki te whakaroa i te roa o te ora o ngā wāhanga, ka whakaratohia e ngā paninga silicon carbide te pakari me te pumau o te pāmahana, ka whai hua ai mō te whakamahinga roa. Mā te whiriwhiri i tētahi mata kua pania ki te silicon carbide, ka whai hua ngā ahumahi i te whakaiti i ngā utu tiaki, te whakapai ake i te pono o ngā taputapu, me te whakapai ake i te whai huatanga o te mahi.
