Granite yog ib lub pob zeb tshwm sim uas tau siv rau lub sijhawm ntev hauv cov khoom siv wafer.Nws yog lub npe hu rau nws cov khoom zoo heev uas muaj thermal expansion, siab rigidity thiab zoo stability.Txawm li cas los xij, zoo li txhua yam ntaub ntawv, granite muaj nws tus kheej cov teeb meem uas tuaj yeem cuam tshuam qhov zoo ntawm cov khoom siv wafer.
Ib qho ntawm cov teeb meem loj ntawm granite yog nws txoj kev nyiam tawg lossis tawg.Qhov no yog vim muaj cov microcracks uas tuaj yeem tshwm sim thaum lub sijhawm tsim cov pob zeb.Yog tias cov microcracks no tsis raug txheeb xyuas thiab kho kom raug, lawv tuaj yeem nthuav tawm thiab ua rau cov khoom tsis ua haujlwm.Txhawm rau tiv thaiv qhov no los ntawm qhov tshwm sim, cov cuab yeej ua lag luam yuav tsum siv cov granite zoo uas tau kho thiab kuaj xyuas kom ntseeg tau tias tsis muaj microcracks.
Lwm qhov tsis xws ntawm granite yog nws qhov cuam tshuam rau corrosion.Yog tias cov khoom siv granite los rau hauv kev sib cuag nrog corrosive ib puag ncig, nws tuaj yeem pib degrade dhau sijhawm.Qhov no tuaj yeem ua rau cov khoom puas tsuaj lossis ua haujlwm tsis zoo.Txhawm rau tiv thaiv qhov no, cov tuam txhab tsim khoom yuav tsum xyuas kom meej tias cov granite siv hauv lawv cov cuab yeej raug kho thiab coated kom tsis txhob muaj kev xeb tshwm sim.
Granite kuj tseem ua rau warping dhau sijhawm vim nws cov khoom siv thermal.Qhov no yog vim granite muaj cov coefficient tsawg heev ntawm thermal expansion, txhais tau hais tias nws tsis nthuav lossis cog lus ntau thaum raug hloov pauv hauv qhov kub thiab txias.Txawm li cas los xij, txawm tias me me ntawm kev nthuav dav lossis kev cog lus tuaj yeem ua rau warping hauv cov cuab yeej siv lub sijhawm.Nws yog ib qho tseem ceeb uas cov chaw tsim khoom siv cov khoom siv thermal ntawm granite rau hauv tus account thaum tsim lawv cov khoom siv los tiv thaiv qhov tsis xws luag.
Thaum kawg, granite qhov ntxeem tau tuaj yeem ua rau muaj teeb meem nrog kev sib kis.Yog tias cov granite tsis raug kaw kom zoo, nws tuaj yeem nqus cov pa paug uas tuaj yeem cuam tshuam qhov zoo ntawm wafer.Qhov no tuaj yeem ua rau poob qis thiab poob ntau lawm.Txhawm rau tiv thaiv qhov no, cov neeg tsim khoom yuav tsum tau muab cov granite kom zoo kom tsis txhob muaj cov kab mob sib kis los ntawm kev nqus.
Hauv kev xaus, granite yog ib qho khoom siv zoo heev rau kev siv cov khoom siv wafer.Txawm li cas los xij, nws yog ib qho tseem ceeb kom paub txog nws qhov tsis xws luag thiab ua tib zoo ceev faj kom tsis txhob tshwm sim.Nrog kev tu thiab tu kom zoo, cov khoom siv granite tuaj yeem ua haujlwm tau ntau xyoo, muab cov wafers zoo rau kev lag luam semiconductor.
