Granite yog ib lub pob zeb ntuj uas paub txog nws cov kav ntev, lub zog, thiab tsis kam hnav thiab tsim kua muag.Vim tias cov khoom no, nws yog ib qho khoom siv zoo tshaj plaws rau kev siv cov khoom siv hauv kev lag luam semiconductor, xws li cov khoom siv wafer.Hauv tsab xov xwm no, peb yuav tshawb txog ntau qhov zoo uas granite muaj nyob rau hauv cov ntsiab lus ntawm wafer ua khoom siv ntau lawm.
Ua ntej thiab foremost, granite muaj ib tug tsawg coefficient ntawm thermal expansion.Qhov no txhais tau hais tias nws tsis nthuav lossis cog lus loj heev hauv kev teb rau kev hloov pauv hauv qhov kub thiab txias.Qhov no yog ib qho khoom tseem ceeb tshwj xeeb rau cov khoom siv ua wafer, uas yuav tsum tau tswj xyuas kom meej meej kom tsis txhob ua rau cov khoom siv wafer ua tiav.Yog tias cov khoom siv tau tsim los ntawm cov khoom siv nrog ntau dua coefficient ntawm thermal expansion, ces txawm tias qhov kev hloov me me ntawm qhov kub thiab txias tuaj yeem ua rau cov cuab yeej nthuav dav lossis kev cog lus, ua rau qhov tsis raug ntawm kev ua cov wafers.
Lwm qhov zoo ntawm granite yog nws qib siab ntawm kev ruaj ntseg.Nws yog ib qho khoom siv tsis txaus ntseeg thiab tawv uas tsis yooj yim hnav lossis eroded dhau sijhawm.Qhov no txhais tau hais tias cov cuab yeej 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 tshwj xeeb ntawm qhov ruaj khov, uas txhais tau hais tias nws tuaj yeem tswj tau nws cov duab thiab loj nyob rau lub sijhawm txawm tias muaj kev hloov pauv hauv qhov kub thiab av noo.
Granite kuj tseem tiv taus tshuaj lom neeg corrosion, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv nyob rau hauv cov tshuaj hnyav hnyav hauv kev ua wafer.Ntau cov tshuaj siv hauv kev ua wafer tuaj yeem ua rau cov hlau thiab lwm yam khoom siv, ua rau kev puas tsuaj lossis txawm tias tsis ua haujlwm ntawm cov khoom siv.Granite, txawm li cas los xij, feem ntau impervious rau cov tshuaj no, tso cai rau nws ua haujlwm zoo thiab tswj nws cov qauv kev ncaj ncees nyob rau lub sijhawm.
Ntxiv rau cov yam ntxwv ua haujlwm no, granite muaj ntau qhov zoo dua thaum siv cov khoom siv wafer.Nws muaj qhov zoo nkauj txaus nyiam, nrog cov qauv tshwj xeeb uas yog ob qho tib si zoo nkauj thiab tshwj xeeb.Qhov no tuaj yeem yog qhov tseem ceeb rau kev txiav txim siab rau high-end semiconductor cov chaw tsim khoom uas qhov tshwm sim tseem ceeb.Ntxiv mus, granite yog cov khoom siv ntuj tsim uas muaj kev ruaj ntseg thiab ib puag ncig tus phooj ywg, ua rau nws yog ib qho kev xaiv zoo nkauj rau cov tuam txhab uas tseem ceeb rau kev ruaj ntseg.
Hauv kev xaus, qhov zoo ntawm kev siv granite hauv wafer ua khoom siv ntau lawm yog ntau thiab tseem ceeb.Los ntawm nws qhov qis coefficient ntawm thermal expansion mus rau nws cov qib siab ntawm kev ruaj ntseg thiab tsis kam mus rau tshuaj corrosion, granite muaj cov yam ntxwv tshwj xeeb uas ua rau nws yog cov khoom siv zoo tshaj plaws rau kev lag luam no.Yog li ntawd, nws yog qhov kev xaiv zoo tshaj plaws rau ntau lub tuam txhab semiconductor thoob ntiaj teb, thiab nws zoo li yuav nyob twj ywm li ntawd rau yav tom ntej.
