Master High-Purity Crystal Growth oo leh Silicon Carbide Crucibles

1. Hordhac

Shalay uun, shirkadda weyn ee semiconductor TSMC ayaa ku dhawaaqday $4 bilyan oo balaarin ah xarunteeda Arizona si wax looga qabto gabaabsiga caalamiga ah. Maalgelintan baaxadda leh waxay iftiiminaysaa saxnaanta xad dhaafka ah ee looga baahan yahay wax soo saarka silikoon crystal - halkaasoo silikon carbide crucibles waxay ciyaaraan door lama huraan ah. Weelashan khaaska ah waxay sameeyaan wadnaha foornooyinka koritaanka crystal, taasoo awood u siinaysa waferrada silikoon ee aadka u saafiga ah ee awooda talefankeena casriga ah, EVs, iyo kaabayaasha AI.

2. Hadafka Crucible's: Koritaanka kiristaalo qumman

Habka Czochralski, silikoon polycrystalline wuxuu ku dhalaali karaa 1,414 ° C gudaha saqafka. Karistan abuur ah ayaa dhexda qubeyska la shubay oo si tartiib ah uga baxay, samaynaysa hal-crystal ingot ah oo saafi ah. Tani waxay dalbanaysaa weel aan wasakhayn doonin silikoonka ama ku fashilmi doonin baaskiil kulaylka naxariista leh. Waa meesha silsiladda carbide crucibles dhalaalaya.

Sirtooda ayaa ku jirta silicon Guryaha gaarka ah ee carbide: kulaylka kuleylku saddex jibaaran yahay kan birta aan la taaban karin, qallafsanaanta cajiibka ah (labaad oo kaliya dheeman), iyo balaarinta kulaylka eber ku dhow. Weelasha ka samaysan silikoon carbide (RBSiC) ee dib loo soo celiyay waxay ilaalinayaan sharafta qaabdhismeedka iyada oo loo marayo boqollaal wareegyo, oo ka duwan beddelka quartz ee ka jaban ee si degdeg ah hoos u dhigaya.

3. Waa maxay sababta Silicon Carbide u maamusho Foornooyinka Semiconductor

Marka la dooranayo agabka qallafsan, injineeradu waxay is barbar dhigaan tilmaamayaasha waxqabadka muhiimka ah. Aan baaro sida silicon carbide waxay ka soo horjeedaa beddelka caadiga ah:

• Boron carbide vs silicon carbide: Iyadoo boron carbide ay bixiso nuugista neutron-ka sare, silikoon carbide waxay bixisaa iska caabin shoog kulaylka wanaagsan iyo wax ku oolnimada koritaanka crystal.
• Silicon nitride crucibles: In kasta oo silikoon nitride ceramic ay bixiso adkeysi jaban oo aad u wanaagsan, silikoon carbide crucibles waxay ilaalinayaan kuleylka kuleylka sare (120 W/mK vs 30 W/mK) - oo muhiim u ah qaybinta heerkulbeegga isku midka ah.

Silicon carbide Crucibles waxay gaadhaan heerar faddarayn ka hooseeya 1 ppm. Nadiifintaani waxay ka hortagtaa cilladaha doping-ka ee wafers, taasoo si toos ah u saameyneysa wax-soo-saarka chips. Horumarkii dhawaa ee dahaarka kaydinta uumiga kiimikaad (CVD) ayaa sii wanaajinaya cimrigooda deegaanka silikoon dhalaalaysa.

4. Taageerida Jidka: Qaybaha Silicon Carbide ee Kobaca Crystal

Marka laga reebo crucibles, foornooyinka semiconductor waxay ku jiraan walxo badan oo carbide silicon:

• Tuubooyinka silikoon carbide iyo tuubooyinka mullite silikoon carbide waxay u adeegaan sidii gacmo-gashi heerkulbeeg ah iyo makiinada foornada
• Mashiinnada gubida Silicon carbide waxay xaqiijiyaan duritaanka gaaska saxda ah
• Taarikada nitride-ka silikoon iyo gaashaanka kulaylka silikoon nitride caado ah ayaa ilaaliya qaybaha xasaasiga ah
• RBSiC silikoon carbide tile blocks waxay sameeyaan foornada foornada

Qaybahani waxay abuuraan jawi deggan, wasakh-la'aan ah oo looga baahan yahay koritaanka 300mm crystal ingots - heerka warshadaha hadda.

5. Wixii ka dambeeya Semiconductors: Codsiyada Silicon Carbide lama filaan ah

Waxa xiisaha lihi leh, waxyaabaha la midka ah ee qiimaha foornooyinka ayaa ka dhigaya ceramics silicon carbide ceramics oo caan ku ah jikada:

• Suxuunta dubista dhoobada ee Silicon carbide iyo suxuunta qasacadaysan ayaa si siman u qaybiya kulaylka
• Taarikada cashada ee silikon carbide waxay u adkeysaneysaa shoogga kulaylka foornada ilaa miiska
• Foomamka gaarka ah sida suxuunta dhoobada dhoobada ee silikoon carbide iyo ramekins ayaa helaya taageerada cunto karinta

Noocyada raaxada sida Staub xitaa suuqa khadadka saxanka dubista carbide. Iyadoo alaabtan cunto karinta ay isticmaalaan farsamooyinka wax soo saarka ee kala duwan, waxay wadaagaan faa'iidooyinka alaabta asaasiga ah ee laga faa'iidaysto goobaha warshadaha.

6. Soohdimaha Mustaqbalka iyo Cusbooneysiinta Agabka

Sida chipmakers ay riixaan wafers 450mm ka weyn, soosaarayaasha crucible waxay kaga jawaabaan hal-abuurnimo:

• Tuubooyinka dhoobada silikoon carbide ee daloola ee fidinta gaasta horumarsan
• Silikon carbide dheeman shiida saxannada loogu talagalay makiinada saxda ah
• Kobaca suuqa budada nitride silikoon nadiif ah oo sarreeya qaybaha isku-dhafan

Cilmi-baarista joogtada ah ee silikoon carbide piezoelectric saxannada dhoobada ayaa laga yaabaa inay awood u siiso la socodka nidaamka isku dhafan ee jilbaha xiga.

7. Gunaanad

Laga soo bilaabo awoodsiinta casriga ah ee jeebkaaga ku jira ilaa digsiga foornadaada, dhoobada silikoon carbide ceramics waxay muujinaysaa wax-qabad cajiib ah. Wax soo saarka semiconductor gaar ahaan, silikoon carbide crucibles ayaa weli ah kuwo aan lagu beddeli karin si ay u koraan kiristaalo qumman ee taageeraya adduunkeena dhijitaalka ah. Maaddaama ay jajabku joomatariga yaraadaan oo cabbirada waferku ay kordhaan, weelashan aan la malaynayn waxay sii wadi doonaan inay ciyaaraan doorka jilitaanka ee horumarka tignoolajiyada.
