Txheej txheem cej luam ntawm Sapphire Square Blank Substrate

Lub sapphire square blank substrate, raws li tau piav qhia hauv daim duab, yog ib qho khoom siv lead ua los ntawm txhuas oxide (Al₂O₃) uas muaj qhov huv si thiab tsim los siv rau hauv kev tsim kho qhov muag siab heev, kev tsim khoom siv semiconductor, thiab kev sim cov khoom siv precision. Lub npe nrov rau nws cov khoom siv lub cev thiab tshuaj lom neeg zoo heev, sapphire tau dhau los ua ib qho ntawm cov khoom siv tseem ceeb tshaj plaws hauv kev lag luam uas xav tau kev ruaj khov, kev ruaj khov, thiab kev ua haujlwm optical. Tsim los ntawm cov txheej txheem kev loj hlob ntawm cov siv lead ua, xws li Kyropoulos (KY), Heat Exchange Method (HEM), lossis Czochralski (CZ) cov txheej txheem, cov square blanks no tau tsim ua tib zoo kom ua tau raws li cov qauv zoo tshaj plaws.

Cov yam ntxwv tseem ceeb ntawm Sapphire Square Blank Substrate

Sapphire yog ib lub pob zeb siv lead ua anisotropic uas muaj cov qauv hexagonal lattice, uas muaj kev sib xyaw ua ke ntawm lub zog kho tshuab, kev ruaj khov thermal, thiab kev tiv taus tshuaj lom neeg. Nrog rau qhov ntsuas Mohs hardness ntawm 9, sapphire yog qhov thib ob tsuas yog pob zeb diamond hauv kev tiv taus khawb, ua kom muaj lub neej ntev txawm tias nyob hauv cov xwm txheej kev lag luam abrasive. Nws lub ntsiab lus yaj tshaj 2000 ° C, ua rau muaj kev ua tau zoo hauv qhov chaw kub siab, thaum nws qhov kev poob dielectric qis ua rau nws yog cov khoom siv substrate nyiam rau RF thiab cov ntawv thov hluav taws xob zaus siab.

Hauv thaj chaw kho qhov muag, sapphire qhia txog ntau yam kev sib kis los ntawm ultraviolet tob (~ 200nm) mus txog rau nruab nrab-infrared (~ 5000nm), nrog rau kev sib xws zoo heev thiab birefringence qis thaum taw qhia kom raug. Cov khoom no ua rau sapphire square blanks tsis tseem ceeb hauv cov teb optics-intensive xws li laser systems, photonics, spectroscopy, thiab imaging.

Kev Tsim Khoom thiab Kev Ua Khoom

Txhua lub sapphire square blank substrate raug tsim cov txheej txheem nruj heev, pib nrog cov hmoov alumina nyoos purity siab uas raug tswj hwm kev loj hlob ntawm cov siv lead ua hauv cov cub tawg kub siab. Tom qab cov siv lead ua loj hlob, nws raug taw qhia meej (feem ntau yog C-dav hlau (0001), A-dav hlau (11-20), lossis R-dav hlau (1-102)) kom haum rau cov kev xav tau tshwj xeeb ntawm daim ntawv thov. Tom qab ntawd cov siv lead ua raug txiav ua cov square blanks nrog cov hniav pob zeb diamond-coated, ua raws li kev txiav kom raug kom ua tiav qhov tuab sib xws. Rau cov ntawv thov optical thiab semiconductor, cov nplaim tuaj yeem polished rau atomic-level smoothness, ua tau raws li qhov tiaj tiaj, sib luag, thiab cov lus qhia txog qhov roughness ntawm qhov chaw.
