Madaxa Injineernimada:Dr. Marcus iyo Kooxda Injineerinka Qalabka ee VET Crystal Thermal Field & High-Purity Materials Warbixinta Farsamada:Daraasad Kiis ah oo ku saabsan Qalabka Semiconductor-ka VET iyo Hagaajinta Habka (Lambarka Warbixinta: VET-CS-2025-SAG04)

Soo Koobidda Fulinta & Guudmarka Mashruuca Warshadaha:Soo saarista Wafer-ka Semiconductor & Photovoltaic Macaamiisha:S-AG (Soo saaraha Wafer-ka Semiconductor-ka ee ugu horreeya 300mm, Jarmalka) Geedi socodka:Czochralski (CZ) 12-Inch oo ah Monocrystalline Silicon Crystal oo jiidaya Xalka:Cufnaan Sare Nadiif Sare Isostatic Graphite Crucible (Dambas < 5 ppm) + 5-Axis Saxnaanta CNC Machining + Qaabaynta Heerkulka FEA Natiijooyinka la Tiriyey:Wax soo saarka jiidista kiristaalka ayaa kordhay 14.2%, cimriga adeegga graphite crucible ayaa la kordhiyay 25%, iyo wasakhda dhalaalaysa ee wasakhda ayaa hoos u dhacday ka hooseeya heerka aasaasiga ah ee warshadaha.

Kobaca silikoonka monocrystalline ee Czochralski (CZ), graphite crucible wuxuu u adeegaa qaybta culeyska iyo gudbinta kulaylka ee ugu weyn ee taageerta silikoonka quartz crucible iyo milmay (>1,450°C). Nadiifnimadeeda iyo waxqabadkeeda cadaadiska kulaylka ayaa si toos ah u go'aamiya wax soo saarka jiidista kiristaalka iyo sifooyinka korontada. Alaabada garaafka caadiga ah badanaa waxay keenaan isbeddelka quartz crucible, faafinta wasakhda birta, iyo wasakhda dhalaalka silikoon. Daraasaddan kiiskan waxay faahfaahin ka bixinaysaa sida kooxda injineerinka goobta kuleylka ee sare ee VET ay u habeeyeen graphite graphite isostatic saafiga sare ee S-AG (Jarmalka), iyagoo xallinaya wasakhda wasakhda iyo caqabadaha cadaadiska kulaylka heerkulka aadka u sarreeya si loo gaaro hufnaan kharash oo weyn.

Sidee Saxnaanta Sare ee Garaafiga u Yareeyaan Wasakhowga iyo Cilladaha ku jira CZ Silicon

Gunaanad Muhiim ah: Dahaarka graphite isostatic-ka oo saafi ah oo leh dambas ka yar 5 ppm ayaa si wax ku ool ah u xannibaya faafitaanka walxaha birta ee ku jira dhalaalka silikoon, taasoo si weyn u yareynaysa heerarka kala-baxa kiristaalka iyo kordhinta cimriga sideyaasha tirada yar.

1. Qodobbada Xanuunka Codsiga & Macaamiisha

Intii ay ku shaqeyneysay foornooyinka CZ silicon ee heerka semiconductor-ka ah ee 12-inch (300mm) ee Jarmalka, macaamiisha S-AG waxay la kulmeen hoos u dhac daran oo ku yimid cimriga sideyaasha tirada yar iyo heerarka kala-baxa geeska oo sarreeya. Tijaabada ayaa muujisay in wasakhda dambaska raadadka ah (B, Fe, Cu) ee ku jirta graphite crucibles-ka caadiga ah ay galeen derbiyada quartz crucible inta lagu jiro jiidista joogtada ah heerkulka ka sarreeya 1,450°C. Wasakhdahan ayaa si toos ah ugu faafay dhalaalka silicon, taasoo carqaladeysay hufnaanta qaab-dhismeedka kiristaalka waxayna ka hortagtay in waferku ay gaaraan heerarka tayada SEMI C12 iyo ISO 9001.

2. Xalka Injineernimada & Hirgelinta Geedi socodka

Kooxda injineernimada VET waxay bixiyeen gaas graphite isostatic ah oo cufnaan sare leh oo loo mariyey nadiifinta gaaska halogen-ka heerkulka sare leh:

• Xulashada Agabka iyo Nadiifinta Qotoda dheer:Badar khafiif ah (cabirka hadhuudhka ≤ 8 μm) iyo cufnaanta sare (≥ 1.85 g/cm³) isostatic graphite ayaa lagu nadiifiyay foorno faaruq ah muddo 72 saacadood ah wareegga gaaska halogen-ka heerkulka sare leh, taasoo keentay in wadarta guud ee dambaska uu hoos ugu dhaco < 5 ppm.
• Tijaabada Dufcadda GDMS:Spectrometry-ga Buuxinta Buuxinta Buuxinta ee Heerka Sare (GDMS) ayaa loo isticmaalay in lagu baaro wasakhda birta muhiimka ah ee dufcad-dufcad, iyadoo la hubinayo in walxaha wasakhda ah ee asaasiga ah loo dhimay heerarka ppb (fiiri jadwalka xogta ee hoose).

Walax Nadaafad ah	Graphite-ka Caadiga ah ee la soo saaray	VET Nadiif Sare oo Isostatic Graphite ah	Heerka S-AG (SEMI C12)
Dambas Dhammaad ah	≈ 150 ppm	< 3.8 ppm	< 5.0 ppm
Bir (Fe)	12.5 ppm	18 ppb	< 50 ppb
Naxaas (Cu)	3.2 ppm	< 5 ppb	< 10 ppb

Hagaajinta Qaab-dhismeedka Goobta Kulaylka iyo Iska caabbinta Shoogga Kulaylka iyada oo loo marayo Isostatic Graphite Crucibles

Gunaanad Muhiim ah: Hab-dhaqanka kulaylka ee isku midka ah ee isotropic oo ay weheliso xoog farsamo oo sare ayaa si wax ku ool ah uga hortagaya isbeddelka korantada iyo soo saarista jajabyada yar yar inta lagu jiro wareegga kulaylka ee soo noqnoqda.

1. Qodobbada Xanuunka Codsiga & Macaamiisha

S-AG's crucibles-kii asalka ahaa ee la soo saaray ee graphite-ka ayaa si joogto ah ula kulmay ballaarinta kuleylka radial-ka ee aan isku mid ahayn, dildilaaca yar ee derbiga, ama hoos u dhaca ka dib tobanaan wareeg oo kuleyl ah. Tani waxay keentay cadaadis aan sinnayn iyo jilcinta/burburka heerkulka sare ee quartz crucible-ka gudaha, taasoo kicisay xidhitaanka foornada. Celceliska cimriga graphite crucible wuxuu ahaa wax ka yar 180 wareeg oo kuleyl ah, taasoo keentay kharashyo dayactir iyo waqti-dhiman oo weyn.

2. Xalka Injineernimada & Hirgelinta Geedi socodka

Si loo xalliyo isbeddelka cadaadiska kulaylka heerkulka sare, Dr. Marcus wuxuu hoggaamiyay kooxda injineernimada VET iyada oo loo marayo geeddi-socod beddelka saddex-geesoodka ah oo heer-kulka ah:

[Marxaladda 1aad: Baadhista] • Qaabaynta Heerkulka ee FEA • Hagaajinta CTE (4.8×10−&sup6;/K)

[Marxaladda 2: Wax-soo-saarka] • Riixista Qabow ee Isostatic • Xoogga Laab-jeexa ee 45 MPa

[Wejiga 3: Xaqiijinta] • Tijaabo 60-Maalmood ah oo Goobta ah • 220+ Wareegyo Kulayl ah

• Qiimaynta Qaab-dhismeedka & Iswaafajinta Kulaylka (Baadhista):Kooxdu waxay ku samaysay qaabaynta Falanqaynta Qaybta Finite (FEA) ee ku salaysan heerarka kulaylka ee S-AG waxayna dib u habayn ku samaysay qaabka saddex-qaybood ee kala qaybsan ee garaafka. Qaabaynta agabka waxaa loo habeeyay si loo waafajiyo Coefficient of Thermal Expansion (CTE) 4.8×10−/K, iyadoo la gaadhay iswaafajin sare oo leh dahaarka quartz ee 1,450°C iyo baabi'inta xiisadda qanjaruufo farsamo.
• Samaynta Xoogga Sare & Makiinadaha Saxnaanta (Soo-saarista):Cadaadiska Qabow ee Isku-dhafka ah (CIP) wuxuu soo saaray baloogyo garaafit ah oo leh xoog dabacsan oo 45 MPa ah. Mashiinka CNC ee 5-axis ee saxda ah (±0.01mm dulqaad) wuxuu hubiyey in qaybaha ay u adkeysan karaan saameynta farsamada iyo shoogga kulaylka marka lagu shubo boqolaal kiilogaraam oo ah lacag silikoon ah.
• Tijaabada Goobta iyo Xaqiijinta Cimriga (Xaqiijinta):S-AG waxay tijaabo joogto ah oo 60 maalmood ah ku samaysay Jarmalka. Ka dib 220+ wareegyo kuleyl ah (~1,500 saacadood kulayl aad u daran), cabbirradu waxay ahaayeen kuwo aan isbeddelin iyada oo aan lahayn dildilaacyo yaryar, taasoo si guul leh u baabi'isay xidhitaanka foornada oo ay sababtay cilladda dabka.

Isticmaalka Xakamaynta Cadaadiska Kulaylka ee Saxda ah ee Kobaca Silikoonka Monocrystalline ee CZ

Gunaanad Muhiim ah: Hagaajinta isku-dheelitirka joomatari iyo qaybinta gudbinta kulaylka waxay xasilisaa isku-xidhka adag iyo dareeraha, iyadoo yaraynaysa isbeddellada fiirsashada oksijiinta inta lagu jiro koritaanka kiristaalka ee dheeraadka ah.

1. Qodobbada Xanuunka Codsiga & Macaamiisha

Inta lagu jiro jiiditaan dheer oo ah ingots silicon ah oo 12-inji ah oo si xoog leh loo dahaadhay ama aan cillad lahayn, isku-dheelitir la'aanta cadaadiska kulaylka ee isku-xirka adag iyo dareeraha ayaa sababa jahwareerka dhalaalka ee qulqulka. Tani waxay horseedaa isbeddellada fiirsashada oksijiinta ee axial iyo radial, taasoo hoos u dhigaysa wax-soo-saarka dabacsanaanta inta lagu jiro jarista wafer ee xigta.

2. Hirgelinta Farsamada iyo Qiimaha

• Jilidda Goobta Kulaylka:Jilitaanka FEA wuxuu khariidadeeyay waddooyinka gudbinta kulaylka inta u dhaxaysa 1,450°C iyo 1,550°C, isagoo wanaajiyay heerarka dhumucda derbiga ee la shiilay.
• Xakamaynta Dulqaadka Isku-dhafka:Dulqaadka dhumucda derbiga ayaa lagu xaddiday ±0.005mm gudahood, taasoo kordhisay isku dheelitirka kulaylka 18%.

Iyada oo loo marayo xakamaynta cadaadiska kulaylka saxda ah, S-AG waxay gaartay horumar 22% ah oo ku yimid isku-darka fiirsashada oksijiinta ee ingot axial, koror 8% ah oo ku yimid xawaaraha jiidista, iyo hoos u dhac la taaban karo oo ku yimid cilladaha kala-baxa.
