Granite yog ib lub pob zeb uas tshwm sim ntuj tsim uas tau siv ntev heev hauv cov khoom siv ua wafer. Nws paub txog nws cov khoom zoo heev ntawm kev nthuav dav thermal tsawg, kev ruaj khov siab thiab kev ruaj khov zoo. Txawm li cas los xij, zoo li txhua yam khoom siv, granite muaj nws cov teeb meem uas tuaj yeem cuam tshuam rau qhov zoo ntawm cov khoom siv ua wafer.
Ib qho ntawm cov teeb meem loj ntawm granite yog nws txoj kev nyiam tawg lossis tawg. Qhov no yog vim muaj cov kab nrib pleb me me uas tuaj yeem tshwm sim thaum lub sijhawm tsim pob zeb. Yog tias cov kab nrib pleb me me no tsis tau txheeb xyuas thiab kho kom zoo, lawv tuaj yeem nthuav dav thiab ua rau cov khoom siv tsis ua haujlwm. Txhawm rau tiv thaiv qhov no kom tsis txhob tshwm sim, cov chaw tsim khoom siv ua haujlwm yuav tsum siv cov granite zoo uas tau kho thiab sim kom ntseeg tau tias nws tsis muaj kab nrib pleb me me.
Lwm qhov tsis zoo ntawm granite yog nws qhov kev cuam tshuam rau xeb. Yog tias cov khoom siv granite kov cov chaw muaj xeb, nws tuaj yeem pib lwj mus raws sijhawm. Qhov no tuaj yeem ua rau cov khoom siv puas tsuaj lossis tsis ua haujlwm zoo. Txhawm rau tiv thaiv qhov no, cov chaw tsim khoom yuav tsum xyuas kom meej tias cov granite siv hauv lawv cov khoom siv tau kho thiab coated kom zoo kom tiv thaiv kev xeb los ntawm kev tshwm sim.
Granite kuj tseem yuav warping dhau sijhawm vim nws cov khoom thermal uas muaj nyob hauv. Qhov no yog vim granite muaj cov coefficient qis heev ntawm thermal expansion, uas txhais tau tias nws tsis nthuav dav lossis cog lus ntau thaum raug kev hloov pauv ntawm 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 khoom siv dhau sijhawm. Nws yog ib qho tseem ceeb uas tus neeg tsim khoom siv coj cov khoom thermal ntawm granite mus rau hauv tus account thaum tsim lawv cov khoom siv kom tiv thaiv qhov teeb meem no los ntawm kev tshwm sim.
Thaum kawg, granite qhov ntxeem tau tuaj yeem ua rau muaj teeb meem nrog kev ua qias tuaj. Yog tias granite tsis raug kaw kom zoo, nws tuaj yeem nqus cov khoom ua qias tuaj uas tuaj yeem cuam tshuam rau qhov zoo ntawm lub wafer. Qhov no tuaj yeem ua rau lub sijhawm tsis ua haujlwm kim thiab poob ntau lawm. Txhawm rau tiv thaiv qhov no, cov chaw tsim khoom yuav tsum kaw lub granite kom zoo kom tiv thaiv cov khoom ua qias tuaj.
Xaus lus, granite yog ib yam khoom zoo heev rau kev siv rau hauv cov khoom siv ua wafer. Txawm li cas los xij, nws yog ib qho tseem ceeb kom paub txog nws qhov tsis zoo thiab ua raws li cov kev ceev faj tsim nyog los tiv thaiv lawv kom tsis txhob tshwm sim. Nrog kev saib xyuas thiab kev txij nkawm kom zoo, cov khoom siv granite tuaj yeem ua haujlwm tau ntau xyoo, muab cov wafers zoo rau kev lag luam semiconductor.
