Hauv ntiaj teb kev tsim khoom semiconductor, cov khoom siv ua wafer siv los tsim cov integrated circuits, microprocessors, memory chips, thiab lwm yam khoom siv hluav taws xob. Cov khoom siv no xav tau lub hauv paus ruaj khov thiab ruaj khov kom ntseeg tau tias kev ua tiav raug thiab meej.
Lub hauv paus tshuab granite yog ib qho ntawm cov hom hauv paus tshuab nrov siv hauv cov khoom siv ua wafer. Raws li lub npe qhia, nws yog ua los ntawm granite, ib lub pob zeb igneous uas tshwm sim ntuj uas paub txog nws lub zog siab thiab kev tawv.
Lub hauv paus tshuab granite muaj ntau qhov zoo thaum piv rau lwm hom tshuab hauv paus xws li hlau cam khwb cia, hlau, lossis txhuas. Ib qho ntawm cov txiaj ntsig tseem ceeb yog nws cov khoom zoo heev. Kev damping txhais tau tias lub peev xwm ntawm cov khoom siv los nqus cov kev co thiab txo cov suab nrov. Granite muaj qhov zaus resonant qis, uas txhais tau tias nws tuaj yeem damping kev co zoo dua li lwm cov ntaub ntawv. Yog li ntawd, cov khoom siv ua wafer tuaj yeem ua haujlwm ntawm qhov ceev dua, thiab cov chips tsim tawm yog qhov tseeb dua thiab tsawg dua qhov yuam kev.
Lwm qhov zoo ntawm lub tshuab granite yog nws qhov ruaj khov. Granite muaj cov coefficient qis ntawm thermal expansion, uas txhais tau tias nws tsis nthuav dav lossis cog lus nrog kev hloov pauv kub. Cov cuab yeej no ua kom ntseeg tau tias cov khoom siv ua wafer tswj hwm nws qhov tseeb txawm tias raug kev hloov pauv ib puag ncig.
Granite kuj tseem tiv taus kev hnav thiab tsim kua muag thiab tsis yooj yim xeb. Cov yam ntxwv no ua rau nws zoo tagnrho rau kev siv hauv cov chaw ua haujlwm hnyav, qhov twg cov khoom siv ua wafer raug rau cov tshuaj lom neeg thiab cov khoom siv abrasive. Granite kuj yooj yim ntxuav thiab tswj, ua rau nws yog qhov kev xaiv nrov rau cov khoom siv ua wafer.
Xaus lus, lub hauv paus tshuab granite yog ib qho tseem ceeb ntawm txhua yam khoom siv ua wafer. Nws cov khoom zoo heev, kev ruaj khov ntawm qhov ntev, thiab kev tiv thaiv kev hnav thiab tsim kua muag ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tsim cov khoom siv hluav taws xob zoo. Nrog rau kev thov txuas ntxiv rau cov thev naus laus zis siab heev, qhov tseem ceeb ntawm lub hauv paus tshuab granite tsuas yog yuav loj hlob yav tom ntej.
