Silicon Carbide Crucibles Power Next-Gen Semiconductor Crystal Growth

1. Hordhac

Kaliya 24 saacadood ka hor, hormuudka soo saaraha soolarka ee First Solar wuxuu ku dhawaaqay ballaarinta $ 1.1 bilyan ee awoodda wax-soo-saarka khafiifka ah ee Mareykanka, taasoo dib u soo celinaysa xiisaha caalamiga ah ee agabka horumarsan ee semiconductor iyo soosaarka sawir-qaadista. Wadnaha warshadan heerka sare ah waxaa ku jira geesi la yaab leh oo aan la heesin: carbide silicon waa la burburin karaa.

Halka macaamiishu intooda badani ay ku xidhaan carbide silikoon iyo alaabta jikada sida silikoon carbide dhoobada dubista suxuunta ama saxannada cashada, qaabkeeda heerka-warshadaha ayaa lagama maarmaan u ah farsamada casriga ah. Gaar ahaan, silikoon carbide crucibles ayaa awood u siinaya horumarro xagga soo saarista kiristaalo silikoon ultra-saafi ah - oo lagamamaarmaan u ah unugyada soolarka ee jiilka soo socda iyo cutubyada awoodda baabuurta korontada.

2. Waa maxay sababta Silicon-Carbide Crucibles ay u xukumaan kobaca Crystal Heerkul Sare

Marka la eego xoojinta jihada ama hababka Czochralski (CZ) ee loo isticmaalo silikoonka monocrystalline, heerkulku wuxuu dhaafaa 1,500 ° C. Darafyadan, xasiloonida walxaha, caabbinta shoogga kulaylka, iyo firfircoonaanta kiimikaad ayaa ah kuwo aan gorgortan lahayn. Kaaraynta Kalluunka heer sare ah halka ceramics kale ku guuldareystaan.

Si ka duwan silikoon nitride crucibles-kuwaas oo xoog badan laakiin u nugul inay burburaan oo ka sarreeya 1,400°C-Silicon carbide crucibles ilaalinta sharafta qaabdhismeedka ilaa 1,650°C ee jawiga aan shaqaynayn. Tani waxay ka dhigaysaa inay ku habboon yihiin soo-gaadhista muddada dheer ee silikoon dhalaalaysa iyada oo aan wasakhayn dhalaalka.

• Balaadhinta kulaylka hoose ee Silicon carbide waxay yaraynaysaa dildilaaca inta lagu jiro wareegyada kuleylka degdega ah ama qaboojinta.
• Heerkeeda kulaylka sare waxay hubisaa xitaa qaybinta kulaylka, oo muhiim u ah korriinka kareemka isku midka ah.
• Weelasha ka sameysan falcelinta silikon carbide (RBSiC) waxay bixiyaan awood farsamo oo heer sare ah iyo daahirnimo, oo inta badan lagu calaamadiyo sida rbsic silicon carbide tile block derivatives ee buugaagta warshadaha.

3. Codsiga Niche: Semiconductor-Grade Silicon Production

Kiiska isticmaalka ugu baahida badan ee silikoon carbide crucibles waa soo saarista n-nooca monocrystalline silikon ee wax ku oolnimada sare leh ee sawir-qaadista iyo semiconductors-ku-saleysan silikoon. Halkan, xitaa raad raac nijaasta ka waa la burburin karaa waxay burburin kartaa hanti dhan oo qiimaheedu yahay tobanaan kun oo doolar.

Soo-saareyaashu hadda waxay caddeeyaan nadiif-sare, silikoon carbide crucibles sinteed leh qaab-dhismeedka hadhuudhka la kontoroolo si looga hortago in walxaha carbide silikoon ay u dhalaaliyaan dhalaalka. Qalabyadani waxay inta badan la midoobaan tuubooyinka dhoobada silikoon carbide iyo tuubooyinka ilaalinta kulaylka si ay u abuuraan nidaam heerkul sare ah oo si buuxda u socon kara.

Waxa xiisaha lihi leh, in kasta oo boron carbide vs silicon carbide doodaha ay ka jiraan hubka iyo abrasives, silikoon carbide ayaa weli ah mid aan caqabad ku ahayn codsiyada aan la taaban karin sababtoo ah dheelitirnaanta qiimaha, wax soo saarka, iyo waxqabadka.

4. Ka baxsan Crucibles: Nidaamka deegaanka ee Silicon Carbide ee wax soo saarka horumarsan

Saynis isku mid ah oo awood u siinaya silikoon carbide crucibles ayaa sidoo kale awood u leh qaybaha kale ee waxqabadka sare leh. Mashiinnada gubida silikoon carbide, dahaarka leben carbide silicon, iyo tiirar dhoobada silikoon carbide ah ayaa si joogto ah loo isticmaalo in foornooyinka la mid ah kuwa guriga kuwa crucibles.

Dhanka kale, qaybaha silikoon nitride-sida gaashaanka kulaylka silikoon nitride ama silikoon nitride giraanta-badanaa waxay u adeegaan doorar dhameystiran aagagga heerkulka hoose ee isla nidaamyada. Si kastaba ha ahaatee, xidhiidhka tooska ah ee silikoon dhalaalaysa, silikoon carbide waa mid aan la bedeli karin.

Xataa qaybaha u muuqda in aan xidhiidh la lahayn, wax-ku-beddelka walxaha ayaa iftiimaya: tuubbooyinka dhoobada silikoon carbide waxay gacanta ku hayaan gaaska daxalka ah ee maraqyada semiconductor-ka, halka saxanadaha carbide ee silikoon iyo qalabka wax lagu shiidi karo ay dhaldhalaan korriinka ka dib. Haddana kuwan midkoodna macno ma yeelanayaan la'aanteed curiyaha bilaabaya hawsha.

5. Fikradaha khaldan iyo Xaqiiqooyinka Suuqa

Jahawareerka caadiga ah wuxuu ka yimaadaa alaabooyinka macaamiisha ah ee lagu calaamadiyay 'silicon carbide ceramic dinnerware' ama 'silikon carbide dubista saxan dhoobo ah'. Kuwani caadi ahaan waa alaab-dhagax-dhagax leh oo leh silikoon carbide oo lagu daray iska caabbinta shoogga kulaylka-ma aha kuwa aadka u saafiga ah, dhoobada cufan ee loo isticmaalo weelasha warshadaha.

Crucibles silikoon carbide warshadeed run ah waa qaybo la farsameeyay, inta badan caadadii ay sameeyeen aasaaso gaar ah. Ma wadaagaan hab-soo-saar wax-soo-saar leh silikoon carbide ceramik saladh ama saxannada kirismaska, in kasta oo magac la mid ah.

Sidoo kale, iyadoo suuqa budada silikoon nitride-ka nadiifka ah uu u korayo hawada hawada iyo xadhkaha goosashada, kama aysan barakicin silikoon carbide ee codsiyada qallafsan-mana la filayo, marka la eego xaddidaadyada kuleylka aasaasiga ah.

6. Gunaanad

Sida dunidu ugu tartamayso tamar nadiif ah iyo koronto, silikoon carbide crucible-ka hooseeya ayaa weli ah linchpin silsiladda sahayda ee semiconductor sare iyo tignoolajiyada qorraxda. Isku darka u gaarka ah ee adkeysiga kulaylka, xasiloonida kiimikada, iyo xoogga farsamada waxay hubisaa inay ku sii jiri doonto mid muhiim u ah niche, wax soo saarka qiimaha sare leh sanadaha soo socda - aad uga fog jikada ama miiska cashada.

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 Silicon. 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.
