Quartz wafer side doon

Taageerada doonta Semixlab quartz waa qalab qaadis heersare ah oo loogu talagalay semiconductor, photovoltaic, LED iyo saxnaanta warshadaha elektiroonigga ah. Waxay ka samaysan tahay walxo quartz synthetic oo nadiif ah oo sarreeya. Sida isticmaalka asaasiga ah ee hababka heerkulka sare, taageerada doonyaha quartz waxay noqdeen kuwa ugu fiican ee wafers, wafers silicon, substrates galaas iyo qaybaha kale ee saxda ah ee faafinta, annealing, oxidation, CVD ( kaydinta uumiga kiimikada) iyo hababka kale sababtoo ah xasillooni heerkuleed oo heer sare ah, qallafsanaan kiimikaad iyo caawinta macaamiisha waxtarka leh ee habka nolosha.

Xaaladaha codsiga ama qalabka: 

Qaybinta Semiconductor, annealing, oksaydhation, iyo CVD (Qaybsiga Uumiga Kiimikada).

Qaabaynta alaabtayada waxaa inta badan loo isticmaalaa LED, wareegga isku dhafan ee IC, jiilka saddexaad ee semiconductor, photovoltaic iyo warshadaha kale. Semixlab waxay leedahay R&D xooggan, wax soo saar iyo tijaabin isku dhafan iyo awoodo xaqiijin. Isla mar ahaantaana, waxaan si joogto ah u hagaajineynaa tignoolajiyadayada iyo qalabkayaga maalgelinta tobanaan milyan sanadkii.

Adeegyada loo habeeyay

Si loo daboolo baahiyo kala duwan, waxaan bixinaa adeegyo is-beddelid dabacsan waxaanan taageernaa hagaajinnada cabbirka soo socda:

Qeexitaannada cabbirka: La qabso qaybo kala duwan sida 8 inch iyo 12 inch, ama habayn qaab-dhismeedka gaarka ah iyadoo loo eegayo sawirrada macaamiisha.

Daaweynta dusha sare: ciid-qarxinta ikhtiyaarka ah, dahaarka (sida daahan silikoon carbide) iyo hababka kale si kor loogu qaado ku habboonaanta xaaladaha gaarka ah.

Isku-dhafka dheeraadka ah: Waxaa lagu dhejin karaa tiirarka quartz, baffles iyo qaybo kale si loo sameeyo nidaam qaadis dhammaystiran.

Nidaamka hubinta tayada

Tijaabada alaabta ceeriin: Ciid quartz saafi ah oo la soo dejiyay, oo ay falanqeysay ICP-MS (wax eegitaanka balaasmaha mass spectrometry si firfircoon ugu lammaan).

Xakamaynta habka: Mashiinka saxda ah ee CNC + tijaabinta iswada, dulqaadka cabbirka muhiimka ah ≤± 0.05mm.

Baakadaha nadiifka ah: Nooca 100 baakooyinka deegaanka aadka u nadiifka ah si looga fogaado wasakheynta gaadiidka.

Xaaladaha codsiga caadiga ah

Wax-soo-saarka Semiconductor: waxaa loo isticmaalaa kicinta heerkulka sare, oxidation iyo habka dhigista filimada khafiifka ah ee foornooyinka fidsan iyo foornooyinka toosan.

Warshadaha sawir-qaadista: Qaadashada iyo gudbinta unugyada PERC iyo TOPCon ee PECVD, faafinta fosfooraska iyo hababka kale.

Epitaxy LED: Meelaynta saxda ah iyo heerkulka sare ee epitaxial kobaca sapphire substrates ee qalabka MOCVD.

Goobta cilmi-baarista: Qalabaynta walxaha iyo tijaabinta shaybaarka foornooyinka heerkulka sareeyo iyo bay'adaha faakuumka.

1. Iska caabin heerkul sare oo heer sare ah

Taageerada doonta quartz waxay u adkeysan kartaa jawiga heerkulka sare ee ka sarreeya 1200 ℃ muddo dheer, oo leh iskudar balaadhinta kulaylka oo aad u hooseeya (qiyaastii 5.5 × 10⁻⁷ / ℃). Waxay weli sii wadi kartaa xasilloonida qaabdhismeedka iyada oo la raacayo qaboojinta degdega ah iyo xaaladaha kuleylka, iska ilaalinta dildilaaca ama qallafsanaanta kadeedka kulaylka, iyo hubinta habka dib u soo celinta.

2. Nadiifinta aadka u sareysa iyo firfircoonida kiimikada

Laga sameeyay 99.99% ama in ka badan oo ciid quartz nadiif ah, roob la'aan, wasakh la'aan, si wax ku ool ah uga hortagto ions birta ama wasakhda wasakhaysan ee dusha sare ee waferka heerkulka sare, gaar ahaan ku habboon hababka horumarsan ee leh shuruudaha nadaafadda adag (sida wax soo saarka chip ee ka hooseeya 7nm).

3. Qaab dhismeedka saxda ah

Dusha sare ee taageerada doontu waxa lagu qurxiyey sax sare ( qallafsanaanta Ra≤0.2μm), oo ku qalabaysan qaab-dhismeedka boosaska la aqoonsan yahay, kaas oo si adag u qaadi kara substrates cabbirro kala duwan ah (sida 8/12-inch wafers), hubinta kuleylinta isku midka ah iyo wareegga gaaska, iyo hagaajinta isku midka ah nidaamka.

4. Nolol adeeg oo aad u dheer

Marka la barbardhigo garaafyada dhaqameed ama sidayaal dhoobada ah, walxaha quartz waxay leeyihiin iska caabin adag oo daxalka ah, heerka luminta hooseeya ee jawiga acidic / alkaline, iyo isticmaalka joogtada ah ee isticmaalka wuxuu gaari karaa bilaha 12-24, si weyn u yareynaya kharashka macaamiisha.
