Sapphire Ingot Growth Equipment Czochralski CZ Txoj Kev Ua 2inch-12inch Sapphire Wafers

Lus piav qhia luv luv:

Sapphire Ingot Growth Equipment (Czochralski Method) yog ib qho kev txiav-ntug uas tsim los rau kev ua siab dawb huv, tsis muaj teeb meem sapphire ib leeg-crystal loj hlob. Czochralski (CZ) txoj kev ua kom muaj kev tswj xyuas meej ntawm cov noob siv lead ua rub ceev (0.5-5 mm / h), kev sib hloov (5-30 rpm), thiab kub gradients nyob rau hauv iridium crucible, ua axisymmetric crystals txog li 12 ntiv tes (300 mm) hauv txoj kab uas hla. Cov cuab yeej no txhawb nqa C / A-plane siv lead ua kev taw qhia tswj, ua kom muaj kev loj hlob ntawm optical-qib, hluav taws xob-qib, thiab doped sapphire (xws li Cr³⁺ ruby, Ti³⁺ hnub qub sapphire).

XKH muab cov kev daws teeb meem kawg-rau-kawg, suav nrog cov khoom siv kho kom haum (2-12-nti wafer ntau lawm), txheej txheem kev ua kom zoo (qhov tsis xws luag <100/cm²), thiab kev cob qhia, nrog rau cov zis txhua hli ntawm 5,000+ wafers rau cov ntawv thov xws li LED substrates, GaN epitaxy, thiab ntim khoom semiconduct.

Txoj Cai Ua Haujlwm

Txoj kev CZ ua haujlwm los ntawm cov kauj ruam hauv qab no:
1. Melting Raw Materials: High-purity Al₂O₃ (purity>99.999%) yog melted nyob rau hauv ib tug iridium crucible ntawm 2050-2100 ° C.
2. Noob Crystal Introduction: Ib lub noob siv lead ua tau qis rau hauv cov yaj, ua raws li kev rub nrawm los ua ib lub caj dab (inch <1 mm) kom tshem tawm cov dislocations.
3. Lub xub pwg tsim thiab Loj Loj: Qhov rub nrawm yog txo mus rau 0.2–1 mm / h, maj mam nthuav cov siv lead ua txoj kab uas hla mus rau lub hom phiaj loj (xws li 4–12 ntiv tes).
4. Annealing thiab Cooling: Cov siv lead ua yog txias ntawm 0.1–0.5 ° C / min kom txo tau thermal stress-induced cracking.
5. Compatible Crystal Hom:
Electronic Qib: Semiconductor substrates (TTV <5 μm)
Optical Qib: UV laser qhov rais (transmittance> 90% @ 200 nm)
Doped Variants: Ruby (Cr³⁺ concentration 0.01–0.5 wt.%), xiav sapphire tubing
