Granite yog lub pob zeb ntuj uas tau dhau los ua ib feem tseem ceeb ntawm cov khoom siv wafer vim nws cov khoom tshwj xeeb.Hauv tsab xov xwm no, peb yuav tham txog cov yam ntxwv tseem ceeb ntawm granite thiab nws siv li cas hauv cov khoom siv wafer.
Granite yog dab tsi?
Granite yog ib hom pob zeb uas tsis muaj zog uas muaj cov qauv crystalline thiab muaj ntau yam minerals, xws li quartz, feldspar, thiab mica.Nws yog ib qho ntawm cov pob zeb uas nyuaj tshaj plaws thiab tiv taus hnav thiab tsim kua muag, ua rau nws zoo meej rau kev siv hauv kev lag luam ib puag ncig.Lub zog thiab kav ntev ntawm granite ua rau nws yog ib qho khoom siv zoo tshaj plaws rau lub hauv paus tshuab thiab cov khoom siv.
Siv Granite hauv Wafer Cov Khoom Siv Ua Haujlwm
Muaj ntau txoj hauv kev uas granite siv rau hauv wafer ua khoom siv.Qee qhov kev siv ntau tshaj plaws suav nrog:
Wafer Chucks
Wafer chucks yog siv los tuav silicon wafers nyob rau hauv qhov chaw thaum lub sij hawm sib txawv ntawm wafer ua.Granite yog cov khoom siv zoo tshaj plaws rau wafer chucks vim tias nws muaj qhov coefficient tsawg ntawm thermal expansion, uas txhais tau tias nws tsis cuam tshuam los ntawm kev hloov kub.Qhov kev ruaj ntseg no yog qhov tseem ceeb rau kev tswj xyuas qhov tseeb xav tau thaum lub sijhawm ua haujlwm wafer.
Cov Qauv Txheej Txheem
Granite kuj tseem siv los ua cov khoom siv, xws li tshuab hauv paus, ncej, thiab kab.Cov khoom no yuav tsum tau ua kom ntev thiab nruj kom tiv taus qhov kev vibrations thiab kev ntxhov siab uas tshwm sim thaum lub sij hawm ua wafer.Granite muab qhov yuav tsum tau muaj kev ruaj ntseg, xyuas kom cov cuab yeej tswj nws qhov tseeb thiab raug.
Polishing Pads
Polishing pads yog siv los txhuam thiab du nto ntawm silicon wafers.Granite yog siv los ua cov ntaub qhwv no vim nws muaj qhov sib txawv ntawm qhov zoo nkauj uas muab cov txiaj ntsig zoo ib yam.Lub pob zeb kuj tseem tiv taus hnav thiab tsim kua muag, txhais tau tias cov ntaub qhwv tuaj yeem siv tau ntau zaus tsis hnav sai.
Cov txiaj ntsig ntawm Kev Siv Granite hauv Wafer Cov Khoom Siv Ua Haujlwm
Muaj ntau yam txiaj ntsig ntawm kev siv granite hauv wafer ua khoom siv.Qee qhov txiaj ntsig no suav nrog:
Kev ruaj ntseg
Granite muaj qis coefficient ntawm thermal expansion, uas txhais tau hais tias nws tsis cuam tshuam los ntawm kev hloov kub.Qhov kev ruaj ntseg no ua kom ntseeg tau tias cov cuab yeej ua haujlwm wafer tseem muaj tseeb thiab raug, txawm tias qhov kub thiab txias tshwm sim.
Durability
Granite yog cov khoom siv tawv thiab ruaj khov uas tuaj yeem tiv taus hnav thiab tsim kua muag.Nws muab qhov yuav tsum tau muaj kev ruaj ntseg rau lub hauv paus tshuab thiab cov khoom siv, ua kom cov khoom siv ntev ntev thiab txhim khu kev qha.
Precision
Kev ntxhib los mos ntawm granite kom ntseeg tau tias cov cuab yeej tswj hwm nws qhov tseeb thiab raug.Qhov no yog ib qho tseem ceeb thaum lub sij hawm wafer ua theem uas txawm me me deviations tuaj yeem ua rau tsis lees paub lub wafer.
Xaus
Hauv kev xaus, kev siv granite hauv wafer ua khoom siv yog ib qho tseem ceeb ntawm cov txheej txheem tsim khoom semiconductor.Nws cov khoom tshwj xeeb ntawm kev ruaj ntseg, durability, thiab precision ua rau nws zoo tagnrho cov khoom siv rau hauv lub hauv paus tshuab, cov khoom, thiab polishing pads.Kev siv cov granite hauv cov khoom siv wafer tau txhim kho qhov zoo, qhov tseeb, thiab kev ntseeg siab ntawm kev lag luam semiconductor, kom ntseeg tau tias cov khoom siv hluav taws xob tshiab thiab thev naus laus zis tau tsim nrog cov qauv zoo tshaj plaws.
