Te Wetewete i te Huringa Silikoni Ā-Haumaru: Te Kaha o Haina i roto i ngā Tāpiri Boron Kiriata 6N Parakore-Teitei
I te tihi o te hanga tino tika, ka tīmata ia peke mahi i roto i te silicon semiconductor me te mana whakahaere tino tika i te taumata atomika. Ko te kī ki te whakatutuki i tēnei mana whakahaere kei roto i ngā tāpiri boron tioata tino-teitei. Hei rauemi taketake e kore e taea te whakakapi mō te umanga hiko hou o te ao, ko te boron tioata 6N (te parakore ≥99.9999%), me ōna āhuatanga kore e taea te whakakapi, kua riro hei "kaihoahoa kore e kitea" e hanga ana i ngā maramara hou me ngā taputapu hiko.
He aha i rite ai te 6N ki te tioata?pōronite "pūnaha ora" o te silicon semiconductor?
"Pātene" Momo-P Tika: Ina whakaurua tika ngā ngota boron 6N ki roto i te whatunga silicon semiconductor, ka hangaia he "kōhao" nui e hoatu ana ki te wafer silicon tōna kawe hiko momo-P. Koinei te turanga mō te hanga diode, transistors pānga-marae (FET), tae atu ki ngā ara iahiko whakauru matatini.
Te tūāpapa o te mahi: Ko te whai huatanga, te pumau, me te tere whakawhiti o ngā taputapu haurua-ira e tino whakawhirinaki ana ki te ōritetanga me te parakore o te tāpiringa. Ko ngā poke iti katoa (pēnei i te waro, te hāora, me ngā huānga whakarewa) ka mahi hei mahanga kawe, ka hua ake te pikinga o te ia turuturu me te rahunga o te taputapu. Ko te tioata boron 6N e whakahaere ana i ngā taumata poke ki te taumata wāhanga-mō-ia-piriona (ppb), e whakarite ana i te parakore me te pono o te mahi hiko silicon haurua-ira.
He kaitiaki mō ngā tukanga pāmahana teitei: Mēnā kei runga ake i te 2300°C te ira rewa, he tino pumau te boron tioata. I roto i ngā tukanga uaua pēnei i te tipu tioata kotahi silicon (tikanga Czochralski) te whakamahana rānei i te horapa/whakaurunga katote pāmahana teitei, ka mau tonu te pumau o te boron tioata 6N me te kore e whakauru mai i ngā mea memeha ohorere, ngā hua pirau rānei, kia pai ai te whakahaere me te whakahokinga o te tukanga.
Kua whakamātauhia i roto i ngā tono hou o te ao: He kōwhiringa pono mō ngā kiritaki Kōrea me Hapanihi
Take 1 (Kaihanga anga silicon semiconductor Kōrea-ki-te-Tonga): I whakamahia te paura boron 6N a UrbanMines (99.9999% te parakore, te rahi matūriki 2-3mm) hei tāpiri matua i roto i te oumu karaihe kotahi Czochralski hei whakatipu i ngā ingota silicon semiconductor momo-P kounga teitei me te awhe ātete motuhake mō te hanga maramara arorau matatau.
Take 2 (kaihanga taputapu/wafer epitaxial silicon Hapanihi): I tohua a UrbanMines ki te hoko i te 6N dopant boron parakore (99.9999% te parakore, te rahi matūriki -4+40 mata). Ka whakamahia tēnei dopant i roto i ngā tukanga tipu epitaxial, i ngā tukanga horapa pāmahana-tiketike rānei hei whakahaere tika i te tohatoha kukū boron i roto i te paparanga epitaxial silicon semiconductor, i te rohe hononga rānei, kia tutuki ai ngā whakaritenga pakari o ngā taputapu hiko ngaohiko-tiketike (pēnei i ngā IGBT).
Te Tukunga o Haina: Ngā Painga Rautaki o te 6N Crystalline Boron
I te aro atu ki te pikinga o te tono nui mai i ngā rohe matua o te ao mō ngā rauemi haurua-ā-ira pērā i a Kōrea ki te Tonga, Hapani, me te Hononga o Amerika, kua whakatūria e tā mātou kamupene he painga nui ki te whakaputa me te tuku i roto i te mara o ngā rauemi boron parakore teitei:
1. Ngā whanaketanga hangarau me ngā ōhanga tauine: Mā te rangahau me te whanaketanga tonu, kua mōhiotia e tā mātou kamupene te tukanga whakaputa tauine nui mō te boron β-rhombohedral parakore-teitei (te āhua tino pumau). Mā tēnei ka taea e mātou te tuku i te whānuitanga katoa o ngā taumata parakore, mai i te 99% ki te 6N (99.9999%) me te teitei ake. Mā tā mātou kaha whakaputa pumau ka taea e mātou te whakatutuki i ngā ota nui mai i ngā kiritaki nui o te ao (e whakaatuhia ana e tā mātou tono ia marama mō te 50kg o te boron amorphous mō ngā tono rā).
2. Pūnaha whakahaere kounga tino pakari: I runga i ngā paerewa o te ao mō ngā haurua-haurua, kua whakatūria e mātou he pūnaha whakahaere me te whakahaere tino ma mō te tukanga katoa, e kapi ana i te tātari rauemi mata, te hanga tauhohenga, te purenga me te whakamahine (pēnei i te rewa ā-rohe me te whakakore korehau), te kuru me te whakatauranga, me te takai. Mā tēnei ka whakarite kia tino pai te ōritetanga o ia puranga o ngā tioata boron 6N.
3. Ngā Āheinga Whakaritenga Hōhonu: E mārama ana tā mātou kamupene ki ngā whakaritenga tika o ngā tukanga haurua-ā-ira mō te āhua boron (ngā kirikiri, ngā paura) me te rahi o te matūriki (hei tauira, D50 ≤ 10μm, -200 mata, 1-10mm, 2-4μm, me ētahi atu). E ai ki te tuhinga, "ka taea hoki te hanga ritenga mēnā ka tutukihia ngā whakaritenga rahi matūriki motuhake." Ko tēnei urupare ngāwari te mea nui ki te toa i ngā kiritaki teitei i Kōrea ki te Tonga, i Hapani, me ētahi atu whenua.
4. Ngā Painga Mahi Tahi me te Utu o te Mekameka Ahumahi: Mā te whakamahi i tētahi pūnaha ahumahi ā-rohe whānui me ngā rauemi rauemi mata, kāore e whakarite noa i te kounga teitei te boron tioata 6N engari e whakamanamana ana hoki ki te manawanui pai rawa atu o te mekameka tuku me te whakataetae utu whānui, e whakarato ana i te tautoko rauemi matua pumau, pono, me te whai hua mō te umanga hanga semiconductor o te ao.
