Kev Piav Qhia Luv:

Cov Khoom Siv Loj Hlob Sapphire Ingot (Txoj Kev Czochralski) yog ib lub tshuab tshiab uas tsim los rau kev loj hlob ntawm cov pob zeb sapphire uas muaj qhov huv siab, tsis muaj qhov tsis zoo. Txoj kev Czochralski (CZ) ua rau muaj kev tswj hwm qhov ceev ntawm kev rub cov noob pob zeb (0.5–5 mm/h), kev sib hloov ceev (5–30 rpm), thiab qhov kub thiab txias hauv lub crucible iridium, ua rau muaj cov pob zeb axisymmetric txog li 12 nti (300 mm) hauv txoj kab uas hla. Cov khoom siv no txhawb nqa C/A-plane crystal orientation control, ua rau muaj kev loj hlob ntawm cov pob zeb optical-grade, electronic-grade, thiab doped sapphire (piv txwv li, Cr³⁺ ruby, Ti³⁺ star sapphire).

XKH muab cov kev daws teeb meem txij thaum pib mus txog thaum kawg, suav nrog kev kho cov khoom siv (kev tsim cov wafer 2–12-nti), kev ua kom zoo dua qub (qhov tsis zoo <100/cm²), thiab kev cob qhia txog kev txawj ntse, nrog rau kev tsim tawm txhua hli ntawm 5,000+ wafer rau cov ntawv thov xws li LED substrates, GaN epitaxy, thiab semiconductor packaging.
