Granite yog ib lub pob zeb ntuj uas paub txog nws qhov ruaj khov, lub zog, thiab kev tiv taus kev hnav thiab rhuav. Vim yog cov yam ntxwv no, nws yog ib qho khoom siv zoo tshaj plaws rau kev siv hauv cov khoom siv tsim khoom rau kev lag luam semiconductor, xws li cov khoom siv ua wafer. Hauv tsab xov xwm no, peb yuav tshawb nrhiav ntau yam zoo uas granite muaj nyob rau hauv cov ntsiab lus ntawm kev tsim khoom siv ua wafer.
Ua ntej tshaj plaws, granite muaj cov coefficient qis heev ntawm kev nthuav dav thermal. Qhov no txhais tau tias nws tsis nthuav dav lossis cog lus tseem ceeb hauv kev teb rau kev hloov pauv ntawm qhov kub thiab txias. Qhov no yog ib qho khoom tseem ceeb tshwj xeeb rau cov khoom siv ua wafer, uas yuav tsum tswj hwm qhov kev kam rau siab kom tsis txhob ua puas rau cov wafers mos mos uas tau ua tiav. Yog tias cov khoom siv tau ua los ntawm cov khoom siv nrog cov coefficient siab dua ntawm kev nthuav dav thermal, txawm tias qhov kev hloov pauv me me hauv qhov kub thiab txias tuaj yeem ua rau cov khoom siv nthuav dav lossis cog lus, ua rau muaj qhov tsis raug hauv kev ua cov wafers.
Lwm qhov zoo ntawm granite yog nws qhov ruaj khov siab. Nws yog ib yam khoom siv uas tuab thiab tawv heev uas tsis yooj yim hnav lossis lwj dhau sijhawm. Qhov no txhais tau tias cov khoom siv ua los ntawm granite tuaj yeem siv tau ntau xyoo yam tsis tas yuav hloov lossis kho, txawm tias siv hnyav. Tsis tas li ntawd, granite muaj qhov ruaj khov siab heev, uas txhais tau tias nws tuaj yeem tswj nws cov duab thiab qhov loj me dhau sijhawm txawm tias muaj kev hloov pauv ntawm qhov kub thiab txias lossis av noo.
Granite kuj tseem tiv taus cov tshuaj lom neeg xeb heev, ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv hauv cov chaw muaj tshuaj lom neeg hnyav uas feem ntau siv rau hauv kev ua wafer. Ntau yam tshuaj siv hauv kev ua wafer tuaj yeem xeb rau cov hlau thiab lwm yam khoom siv, ua rau puas tsuaj lossis ua tsis tiav ntawm cov khoom siv. Txawm li cas los xij, Granite feem ntau tsis nkag mus rau cov tshuaj no, ua rau nws ua haujlwm tau zoo thiab tswj nws cov qauv kom ruaj khov raws sijhawm.
Ntxiv rau cov yam ntxwv ua haujlwm no, granite muaj ntau yam zoo dua thaum siv rau hauv cov khoom siv ua wafer. Nws muaj qhov zoo nkauj heev, nrog rau cov qauv noob sib txawv uas zoo nkauj thiab tshwj xeeb. Qhov no tuaj yeem yog qhov kev txiav txim siab tseem ceeb rau cov chaw tsim khoom semiconductor siab uas qhov zoo li tseem ceeb. Ntxiv mus, granite yog cov khoom siv ntuj uas ruaj khov thiab zoo rau ib puag ncig, ua rau nws yog qhov kev xaiv zoo rau cov tuam txhab uas muab qhov tseem ceeb rau kev ruaj khov.
Xaus lus, qhov zoo ntawm kev siv granite hauv kev tsim cov khoom siv wafer muaj ntau thiab tseem ceeb. Txij li nws cov coefficient qis ntawm thermal expansion mus rau nws cov theem siab ntawm kev ruaj khov thiab kev tiv thaiv rau cov tshuaj corrosion, granite muaj cov yam ntxwv tshwj xeeb uas ua rau nws yog cov khoom siv zoo tagnrho rau kev lag luam no. Yog li ntawd, nws yog qhov kev xaiv nyiam rau ntau lub tuam txhab semiconductor thoob ntiaj teb, thiab nws yuav nyob li ntawd rau yav tom ntej.
