Txheej txheem cej luam ntawm Sapphire Square Blank Substrate

Lub sapphire square blank substrate, raws li tau piav nyob rau hauv daim duab, yog ib tug high-purity ib leeg-crystal aluminium oxide (Al₂O₃) tivthaiv tsim rau siv nyob rau hauv advanced kho qhov muag engineering, semiconductor ntaus ntawv manufacturing, thiab precision khoom kuaj. Renowned rau nws cov khoom tshwj xeeb ntawm lub cev thiab tshuaj lom neeg, sapphire tau dhau los ua ib qho ntawm cov khoom siv tseem ceeb tshaj plaws hauv kev lag luam uas xav tau kev ua haujlwm siab, ruaj khov, thiab kev ua haujlwm kho qhov muag. Ua los ntawm cov txheej txheem siv lead ua sophisticated, xws li Kyropoulos (KY), Heat Exchange Method (HEM), lossis Czochralski (CZ) cov txheej txheem, cov square blanks yog tsim los ua kom tau raws li cov qauv zoo tshaj plaws.

Cov yam ntxwv tseem ceeb ntawm Sapphire Square Blank Substrate

Sapphire yog ib qho uniaxial, anisotropic siv lead ua nrog cov qauv hexagonal lattice, muab kev sib xyaw ua ke ntawm cov khoom siv dag zog, thermal stability, thiab tshuaj tiv thaiv. Nrog rau Mohs hardness ntsuam xyuas ntawm 9, sapphire yog thib ob tsuas yog pob zeb diamond nyob rau hauv cov nqe lus ntawm khawb tsis kam, kom ntseeg tau tshwj xeeb ntev ntev txawm nyob rau hauv abrasive industrial tej yam kev mob. Nws cov ntsiab lus melting siab tshaj 2000 ° C, tso cai rau kev ua tau zoo nyob rau hauv qhov chaw kub kub, thaum nws qhov tsis tshua muaj dielectric poob ua rau nws nyiam cov khoom siv rau RF thiab cov ntawv siv hluav taws xob ntau zaus.

Nyob rau hauv qhov chaw kho qhov muag, sapphire nthuav tawm dav dav kis tau los ntawm kev sib sib zog nqus ultraviolet (~ 200nm) los ntawm pom mus rau nruab nrab-infrared (~ 5000nm), nrog rau qhov zoo tshaj plaws optical homogeneity thiab qis birefringence thaum ua kom zoo. Cov khoom no ua rau sapphire square blanks indispensable nyob rau hauv optics-intensive teb xws li laser tshuab, photonics, spectroscopy, thiab imaging.

Kev tsim khoom thiab kev ua haujlwm

Txhua lub sapphire square blank substrate tau dhau los ua cov txheej txheem tsim khoom nruj, pib nrog high-purity raw alumina hmoov raug tswj hwm kev loj hlob ntawm cov khoom siv kub kub. Tom qab cov khoom siv lead ua loj hlob tuaj, nws yog qhov taw qhia meej (feem ntau C-plane (0001), A-plane (11-20), lossis R-plane (1-102)) kom haum rau cov ntawv thov tshwj xeeb. Cov siv lead ua yog ces hlais rau hauv cov square blanks nrog pob zeb diamond-coated saws, ua raws li precision lapping kom ua tiav thickness uniformity. Rau kev siv kho qhov muag thiab semiconductor, qhov chaw tuaj yeem polished rau atomic-theem smoothness, ntsib stringent flatness, parallelism, thiab deg roughness specifications.
