Granite Cheebtsam yog dav siv nyob rau hauv kev tsim cov txheej txheem ntawm LCD panels.Cov khoom no muaj ntau yam khoom uas ua rau lawv zoo tagnrho rau siv hauv cov tshuab uas tsim cov LCD panels.Lawv paub txog lawv cov kev ruaj ntseg siab, zoo heev thermal conductivity, thiab tsis tshua muaj thermal expansion.Qhov kev sib xyaw ua ke ntawm cov yam ntxwv no ua rau lawv cov khoom zoo meej rau ntau yam kev siv xws li metrology, wafer fabrication, thiab lithography.
Ib qho ntawm cov thawj daim ntawv thov rau granite Cheebtsam yog nyob rau hauv zus tau tej cov metrology cov cuab yeej.Cov cuab yeej no yog siv los ntsuas qhov tuab ntawm cov panels, qhov roughness ntawm qhov chaw, thiab lawv qhov loj.Granite muaj kev ruaj ntseg zoo, thiab qhov no yog qhov tseem ceeb rau cov cuab yeej ntsuas ntsuas raws li lawv xav tau kom ruaj khov los tsim cov kev ntsuas raug.Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog nyob rau hauv LCD vaj huam sib luag ntau lawm raws li txawm me me variations nyob rau hauv lub thickness los yog loj tuaj yeem cuam tshuam qhov kev ua tau zoo ntawm cov khoom kawg.Yog li ntawd, granite Cheebtsam yog siv nyob rau hauv zus tau tej cov metrology cov cuab yeej los xyuas kom meej lub siab tshaj plaws precision thiab raug.
Lwm qhov chaw thov rau cov khoom siv granite yog nyob rau hauv kev tsim cov tshuab uas siv los tsim cov silicon wafers.Cov tshuab no yog qhov tseem ceeb hauv kev tsim cov LCD vaj huam sib luag, thiab lawv yuav tsum muaj qhov tseeb thiab ruaj khov.Granite muaj zoo heev rigidity thiab stability, uas ua rau nws cov khoom zoo tagnrho xaiv rau tej tshuab.Tsis tas li ntawd, cov khoom siv granite yog cov tiv taus kev co, uas yog lwm qhov tseem ceeb hauv kev tsim cov silicon wafers.
Hauv cov txheej txheem lithography, cov khoom siv granite yog siv los ua lub hauv paus rau cov rooj kho qhov muag uas yog qhov tseem ceeb hauv cov txheej txheem no.Cov rooj kho qhov muag yuav tsum muaj kev ruaj khov heev, thiab cov khoom siv granite muab cov cuab yeej no, uas yuav pab tau kom muaj qhov tseeb ntawm cov txheej txheem ntau lawm.Ntxiv mus, granite Cheebtsam kuj siv nyob rau hauv zus tau tej cov stepper tshuab.Cov tshuab no yog siv los nthuav tawm cov yeeb yaj kiab photoresist ntawm silicon wafers siv lub teeb ultraviolet.Granite qhov qis thermal expansion ua rau nws yog ib qho khoom siv zoo tshaj plaws los tswj qhov tseeb ntawm cov tshuab no.
Thaum kawg, cov khoom siv granite yog siv rau hauv kev tsim cov tshuab tshuaj xyuas, uas yog tsim nyog los kuaj xyuas qhov tsis xws luag ntawm silicon wafers.Cov tshuab no siv lub teeb ci siab siv los kuaj xyuas qhov tsis raug ntawm qhov saum toj kawg nkaus ntawm wafer.Cov khoom siv granite pab kom muaj kev ruaj ntseg ntawm lub tshuab tshuaj xyuas thiab tiv thaiv kev ua yuam kev hauv cov txheej txheem tshuaj xyuas.
Hauv kev xaus, daim ntawv thov thaj chaw ntawm granite Cheebtsam rau cov khoom siv hauv kev tsim cov txheej txheem ntawm LCD panels muaj ntau thiab ntau haiv neeg.Cov khoom siv cov yam ntxwv tshwj xeeb ua rau nws zoo tagnrho rau siv hauv metrology, wafer fabrication, lithography, thiab tshuaj xyuas cov cav tov.Kev siv cov khoom siv granite hauv cov tshuab no ua kom ntseeg tau tias cov txheej txheem tsim khoom yog qhov tseeb thiab ua haujlwm tau zoo, ua rau kev tsim cov khoom zoo ntawm LCD panels.Yog li ntawd, cov tuam txhab lag luam yuav tsum txuas ntxiv siv cov khoom siv granite hauv lawv cov khoom siv los tswj cov qib siab tshaj plaws hauv lawv cov khoom.
