Waa maxay sababta ay Crucibles Silicon Carbide Muhiim ugu yihiin Kobaca Crystal Semiconductor Sare?

1. Hordhac

48-kii saacadood ee la soo dhaafay, Waaxda Tamarta ee Mareykanka ayaa ku dhawaaqday maalgashi dhan $1.5 bilyan si kor loogu qaado wax soo saarka gudaha ee agabka semiconductor, oo ay ku jiraan crystals silicon aadka u saafiga ah—waxyaabaha muhiimka ah ee wax walba laga bilaabo gawaarida korantada ilaa chips AI. Udub dhexaad u ah habkan wax soo saarka ee tignoolajiyada sare ayaa ku jira muuqaal hoose oo la yaab leh laakiin qayb lama huraan ah: silikoon carbide cufan.

In kasta oo dadka intooda badani ay ku xidhaan carbide silikoon leh abrasives ama biriiga baabuurta, doorkeeda isku-darka agabka horumarsan ayaa aad uga sii takhasus badan-oo aad uga sii daran. Maqaalkani waxa uu dhexda u galayaa sida silikoon crucibles carbide awood wax soo saarka jiilka soo socda semiconductors, iyo sababta beddelka ah sida silicon nitride ama boron carbide si fudud ma sii wadi karaan jawiga baahida.

2. Caqabadda Crucible ee Kobaca Crystal Crystal

Koraaya hal-crystal siliconAasaaska qalabka elektiroonigga ah ee casriga ah-wuxuu u baahan yahay dhalaalidda polysilicon heerkul ka sarreeya 1,414°C (2,577°F) deegaan la xakameeyey, wasakhaysan. Wasakh kasta oo la soo bandhigo inta lagu jiro hawshan waxay burburin kartaa dhammaan dufcaddii wafer-ka, oo ku kacaysa kumannaan doolar.

Garaafyada caadiga ah, in kastoo kulaylku u adkaysto, waxay kaga falceliyaan dhalaalid silicon oo sii daaya wasakhda kaarboonka. Taasi waa meesha silikoon carbide crucible ka iftiimaan. Waxa laga sameeyay carbide silikoon nadiif ah oo nadiif ah, weelashani waxay bixiyaan iska caabin shoog kulayl gaar ah, falcelin yar oo leh silikoon dhalaalaysa, iyo hufnaanta qaabdhismeedka heerkul aad u daran.

3. Waa maxay sababta Silicon Carbide uu uga sarreeyo beddelka

Marka la isbarbar dhigo qalabka loogu talagalay weelasha heerkulka sare leh, injineeradu waxay inta badan miisaamaan fursadaha sida boron carbide vs silicon carbide ama xataa silikoon nitride. Boron carbide, in kasta oo aad u adag, waxay u nugul tahay oksaydhka ka sarreeya 500 ° C waxayna soo bandhigi kartaa boron dopants-aan la aqbali karin codsiyada saxda ah ee semiconductor.

Silikon nitride, in kasta oo aad ugu fiican isticmaalka heerkulka sare (sida gaashaanka kulaylka silikoon nitride caado ah ama silikoon nitride giraangireed), waxa ka maqan hab-dhaqanka kulaylka iyo xasilloonida muddada-dheer ee looga baahan yahay silikoon soo noqnoqda. Intaa waxaa dheer, helitaanka saafiga sare ee silikoon nitride budada suuqa ayaa ah mid xadidan oo qaali ah marka la barbar dhigo wax soo saarka silikoon carbide ee bislaaday.

Taas bedelkeeda, silikoon carbide crucible wuxuu ilaaliyaa qaabkiisa, nadiifnimadiisa, iyo waxqabadkiisa daraasiin wareegyo dhalaalid ah - taas oo ka dhigaysa heerka dahabiga ah ee Czochralski (CZ) iyo hababka kobaca kristal ee sabbaynaysa.

4. Wixii ka dambeeya Crucible: Raadka Wershadaha Ballaaran ee Silicon Carbide

Waxa xiisaha lihi leh, isla agabka maaddooyinka ka dhigaya silikoon carbide ku habboon qoloflayaasha ayaa sidoo kale awood u leh isticmaalkeeda guud ahaan meelo kala duwan. Tusaale ahaan, rbsic silikoon carbide tile blocks line kilns waxtarka sare leh, halka silikoon carbide gubanaya nozzles u adkeyso jawi gubasho daxalka ah ee warshadaha galaaska iyo biraha.

Tuubooyinka dhoobada Silicon carbide-gaar ahaan silikoon carbide thermocouple tuubooyinka ilaalinta iyo tuubooyinka dhoobada silikoon carbide ee heerkul sare—waa heer shaybaadhka iyo foornooyinka warshadaha. Xataa alaabta macaamiisha ah, waxaad ka heli doontaa suxuunta dubista dhoobada silikoon carbide, saxannada cashada ee silikoon carbide ceramik, iyo silikoon carbide ceramic maddiibado adeegaya oo lagu qiimeeyay cimrigooda iyo kuleylkooda.

Dhanka kale, qaybo ka mid ah saxanadaha silikoon carbide discs, silikoon carbide ceramic discs, iyo saxanadaha wax lagu shiidi karo silikoon carbide dheeman ee loogu talagalay dhoobada ayaa soo bandhigaya awooddeeda xajinta. Iyo tuubooyinka, qasabadaha silikoon carbide ceramic tuubooyinka iyo qasabadaha saxanka dhoobada ee silikoon carbide waxay ka faa'iidaystaan ​​iska caabbinta xidhashada ee bilaa dareere, valves nolosha dheer.

5. Mustaqbalka Crucibles Nadiifinta Sare

Maaddaama ay kor u kacday baahida loo qabo semiconductors-bandgap-ballaaran sida silikoon carbide lafteeda (oo loo isticmaalo EV-rogayaasha iyo kaabayaasha 5G), baahida loo qabo nadiif- nadiif ah oo dib loo isticmaali karo ayaa sii kordhaysa. Soo-saareyaashu hadda waxay horumarinayaan qolofyo silikoon carbide ah oo dahaaran oo leh astaamo wasakh hoose ah, riixaya xudduudaha waxa suurtogalka ah ee koritaanka crystal.

Shaybaarada cilmi-baarista qaarkood waxay tijaabinayaan naqshado isku-dhafan-isku-dhafka silikoon carbide crucibles iyo silikoon nitride dhoobada dhoobada-laakin kuwani waxay ahaanayaan tijaabo. Imika, silikoon carbide crucible ayaa weli ah mid aan lagu bedeli karin wax-soo-saarka sare ee wax soo saarka semiconductor-ka.

6. Gunaanad

Laga soo bilaabo awood-siinta chips-ka casrigaaga ilaa awood-siinta teknoolojiyadda tamarta nadiifka ah ee soo socota, silikoon carbide crucible-ka hooseeya ayaa door weyn ka ciyaaraya hal-abuurka casriga ah. Isku darka gaarka ah ee kulaylka, kiimikaad, iyo sifada makaanikada ayaa ka dhigaysa mid aan faa'iido lahayn-laakiin lama huraan ah-mid ka mid ah hababka wax soo saarka ee ugu baahida badan Dunida. Sida silsiladaha sahayda semiconductor-ka caalamiga ah ay u koraan, filo in qaybtan dhoobada ah ee aan la qiyaasi karin ay si adag ugu sii jirto xarunta hawsha.

Mareegahayaga oo la aasaasay Oktoobar 17, 2012, waa shirkad tignoolajiyadeed sare leh oo ay ka go'an tahay cilmi-baarista iyo horumarinta, wax soo saarka, farsamaynta, iibinta iyo adeegyada farsamada ee alaabta qaraabada dhoobada ah sida Sababta. Alaabadayada waxaa ku jira laakiin aan ku xaddidnayn Alaabooyinka dhoobada ah ee Boron Carbide, Alaabta dhoobada ee Boron Nitride, Alaabta dhoobada ee Silicon Nitride, Alaabta dhoobada ee Silicon Nitride, Alaabta dhoobada ee Zirconium Dioxide, iwm.
