Akoranga Take: Te Whakapai Ake i te Hua me te Roanga Ora o te Kume Tioata CZ me ngā Paraihe Karāhe Parakore-Teitei

Kaiārahi Hangarau:Tākuta Marcus me te Rōpū Hangarau Papa Wera me ngā Rauemi Parakore-Teitei a te VET Pūrongo Hangarau:Rangahau Take Rauemi me te Arotau Tukanga a VET (Tau Pūrongo: VET-CS-2025-SAG04)

Whakarāpopototanga Whakahaere me te Tirohanga Whānui o te Kaupapa Ahumahi:Te Hanga Wafer Ārahi me te Photovoltaic Kaihoko:S-AG (Te Kaihanga Wafer Ārahi 300mm Semiconductor, Tiamana) Tukanga:Czochralski (CZ) 12-Inihi Monocrystalline Silicon Crystal Toia Otinga:Para Whakarewa Karāwhite Isostatic Teitei-Kōpiko (Pungarehu < 5 ppm) + Mīhini CNC Tika 5-Tuaka + Tauira Wera FEA Ngā Hua kua Inehia:Kua piki ake te hua kume karaihe mā te 14.2%, kua roa ake te ora o te para karāpeti mā te 25%, ā, kua heke te parahanga o te poke rewa i raro i ngā paerewa paerewa ahumahi.

I roto i te tipu o te silicon monocrystalline Czochralski (CZ), ko te ipu karāpiti te wāhanga matua e kawe ana i te kawenga me te kawe wera e tautoko ana i te ipu quartz me te silicon rewa (>1,450°C). Ko tōna parakore me te mahi ahotea wera e whakatau tika ana i te hua kukume tioata me ngā āhuatanga hiko. He maha ngā wā ka puta te whakarerekētanga o te ipu quartz, te horapa o te poke whakarewa, me te poke rewa silicon i ngā rauemi karāpiti tuku iho. E whakaatu ana tēnei rangahau take i te āhua o te whakarite a te tīma hangarau mara wera matua i VET i ngā ipu karāpiti isostatic parakore teitei mō S-AG (Tiamana), te whakatau i ngā wero poke me te ahotea wera i raro i ngā pāmahana tino tiketike kia eke ki te whai hua nui o te utu.

Me pēhea te whakaiti i te poke me ngā hapa i roto i te CZ Silicon e ngā oko paraihe parakore teitei

Whakatau Matua: Ko ngā oko whakarewa karāhe isostatic teitei-parakore me te nui o te pungarehu < 5 ppm ka ārai i te horapa o te huānga konganuku iti ki roto i te rewa silicon, ka whakaiti nui i ngā tere nekehanga tioata me te whakanui ake i te roanga o te ora o ngā kaikawe iti.

1. Ngā Āwangawanga mō te Taupānga me te Kaihoko

I a ia e whakamahi ana i ngā oumu kume silicon CZ kounga-haurua 12-inihi (300mm) i tana whare hanga i Tiamana, i pāngia te kiritaki S-AG e ngā hekenga nui o te roanga o te ora o ngā kaikawe iti o te ingot me te pikinga o ngā tere nekehanga taha. I whakaatuhia e ngā whakamātautau ko ngā paru pungarehu iti (B, Fe, Cu) i roto i ngā ipu karapiti tikanga i uru ki roto i ngā pakitara ipu karaihe i te wā e kumea tonu ana i ngā pāmahana neke atu i te 1,450°C. I horapa tika atu ēnei poke ki roto i te rewa silicon, ka whakararuraru i te hanganga karaihe, ā, ka ārai i ngā wafers ki te tutuki i ngā paerewa kounga SEMI C12 me ISO 9001.

2. Te Whakatinanatanga o te Otinga Hangarau me te Tukanga

I whakaratohia e te tīma hangarau VET ngā oko whakarewa karāhe isostatic kiato-teitei i tukuna ki te purenga hau halogen pāmahana-tiketike hohonu:

• Kōwhiringa Rauemi me te Whakamaarama Hōhonu:I purea te karāpeti isostatic witi-pai (rahi witi ≤ 8 μm) me te kiato-teitei (≥ 1.85 g/cm³) i roto i te oumu korehau i roto i te huringa hau halogen pāmahana teitei 72-hāora, ā, i heke iho te ihirangi pungarehu katoa ki te < 5 ppm.
• Whakamātautau Puranga GDMS:I whakamahia te High-resolution Glow Discharge Mass Spectrometry (GDMS) hei tirotiro i ngā poke konganuku matua i ia puranga, kia mōhio ai kua whakaitihia ngā huānga poke matua ki ngā taumata ppb (tirohia te ripanga raraunga i raro nei).

Huānga Parakore	Karāwhite Whakaputa Tikanga	VET Graphite Isostatic Teitei-Parakore	Paerewa S-AG (SEMI C12)
Pungarehu Katoa	≈ 150 ppm	< 3.8 ppm	< 5.0 ppm
Rino (Fe)	12.5 ppm	18 ppb	< 50 ppb
Parahi (Cu)	3.2 ppm	< 5 ppb	< 10 ppb
Pōroni (B)	1.8 ppm	12 ppb	< 20 ppb
Nikara (Ni)	4.1 ppm	15 ppb	< 30 ppb

Whai muri i te whakatinanatanga o te whakaputanga, i heke te parahanga o te rewa silicon mā te neke atu i te 85%, ā, i piki ake te roanga o te oranga o te kawe iti o te ingot mā te 32%.

Te Arotau i ngā Hanganga Papa Wera me te Ātete ki ngā Ru Wera mā roto i ngā Paraihe Karāhe Isostatic

Whakatau Matua: Mā te kawe wera isotropic ōrite me te kaha ā-pūkaha teitei ka ārai i te whakarerekētanga o te para me te whakaputanga o ngā kapiti moroiti i te wā e auau ana te huringa wera.

1. Ngā Āwangawanga mō te Taupānga me te Kaihoko

I muri i ngā huringa wera maha, i maha ngā wā ka pāngia ngā oko karāpiti taketake o S-AG e te whānui wera ā-ira kore ōrite, te pakaru o te pakitara, te heke rānei o te raro. Nā tēnei i hua ake ai te ahotea kore ōrite me te whakangawari/hinga o te oko kiripaka o roto i te pāmahana teitei, ka mutu ai te mahi o te oumu. Ko te roanga o te mahi o te oko karāpiti i raro iho i te 180 huringa wera, ā, he nui ngā utu tiaki me te wā kore mahi.

2. Te Whakatinanatanga o te Otinga Hangarau me te Tukanga

Hei whakatau i te rerekētanga o te ahotea wera nui i te pāmahana teitei, i ārahi a Tākuta Marcus i te tīma hangarau VET mā roto i tētahi tukanga whakakapinga e toru ngā wāhanga:

[Wāhanga 1: Tātaritanga] • Te Whakatauira Wera o te FEA • Te Whakatikatika CTE (4.8×10−&sup6;/K)

[Wāhanga 2: Te Hanga] • Te Pēhi Matao Isostatic • Kaha Piko 45 MPa

[Wāhanga 3: Manatoko] • Whakamātautau 60-Rā i te Papa • 220+ Huringa Wera

• Aromatawai Hanganga me te Taurite Wera (Tautuhinga):I whakahaerehia e te tīma te whakatauira o te Tātari Huānga Mutunga (FEA) i runga i ngā pikinga wera o S-AG, ā, i hangaia anō te tahora o te ipu karāhe wehewehe e toru-ngā wahi. I whakatikatikaina te hanganga rauemi kia rite te Tauwehenga Whakawhanui Wera (CTE) i te 4.8×10−&sup6;/K, kia tutuki ai te hototahitanga teitei ki te raina quartz i te 1,450°C, me te whakakore i te kume miihini.
• Te Hanga Kaha-Teitei me te Mīhini Tika (Hanga):Nā te Cold Isostatic Pressing (CIP) i whakaputa ngā poraka karāpeti me te kaha piko 45 MPa. Nā te miihini CNC 5-tuaka tika (±0.01mm te manawanui) i whakarite kia tu atu ngā wāhanga i ngā pānga miihini me te ru wera ina utaina ki ngā rau kirokaramu o te utu silicon.
• Whakamātautau i te Pae me te Whakamana i te Roanga Ora (Manatoko):I whakahaerehia e S-AG tētahi whakamātautau tonu mō ngā rā 60 i Tiamana. Whai muri i ngā huringa wera neke atu i te 220 (~1,500 hāora i te wera nui), kāore i rerekē ngā āhua me te kore he pakaru iti, ā, i angitu te whakakore i ngā kati o te oumu i puta mai i te pakaru o te oko.

Te Whakamahinga o te Mana Whakahaere Taumahatanga Wera Tika i roto i te Tipu Silicon Monocrystalline CZ

Whakatau Matua: Mā te arotau i te ōritetanga ā-ira me te tohatoha kawe wera ka whakau i ngā atanga totoka-wai, ka whakaitihia te rerekētanga o te kukū hāora i te wā e tipu roa ana te tioata.

1. Ngā Āwangawanga mō te Taupānga me te Kaihoko

I te wā e tōia roa ana ngā poro silicon 12-inihi kua pania ki te hinu, kāore rānei he hapa, ka puta te pōrearea o te whakawhiti rewa nā te kore ōrite o te ahotea wera i te atanga totoka-wai. Ka hua ake tēnei i ngā rerekētanga o te kukū hāora axial me radial, ka whakaiti i ngā hua whakamahana i te wā e tapatapahia ana te wafer i muri mai.

2. Te Whakatinanatanga Hangarau me te Uara

• Whakatauira Papa Wera:I maherehia e te whakatauira FEA ngā ara kawe wera i waenga i te 1,450°C me te 1,550°C, me te arotau i ngā pikinga matotoru o te pakitara o te oko.
• Mana Whakahaere Manawanui Āhuatanga:I herea ngā ātete matotoru o te pakitara ki roto i te ±0.005mm, ā, i piki ake ai te ōritetanga wera mā te 18%.

Mā te whakahaere tika i te ahotea wera, i eke a S-AG ki te whakapainga 22% i roto i te ōritetanga o te kukū hāora tuaka o te ingot, he pikinga 8% i roto i te tere kume, me te whakahekenga nui i roto i ngā hapa nekehanga.
