Lub hauv paus tshuab granite tau siv ntau dua hauv kev lag luam ua wafer, vim nws muaj ntau yam zoo dua li cov hauv paus tshuab ib txwm muaj xws li hlau thiab hlau cam khwb cia. Hauv tsab xov xwm no, peb yuav tham txog cov txiaj ntsig ntawm kev siv lub hauv paus tshuab granite rau cov khoom ua wafer.
Ua ntej, granite yog ib yam khoom ruaj khov thiab tawv heev, nrog rau kev tiv taus kev hloov pauv thiab kev co siab heev. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov hauv paus tshuab uas xav tau kev ua haujlwm siab thiab raug. Hauv kev ua wafer, txhua qhov kev hloov pauv me me lossis kev co tuaj yeem muaj kev cuam tshuam loj rau qhov zoo ntawm cov khoom. Los ntawm kev siv lub hauv paus tshuab granite, lub tshuab muaj peev xwm ua tiav qib kev ua haujlwm raug thiab raug, ua rau cov khoom zoo dua.
Qhov thib ob, granite muaj cov coefficient qis heev ntawm thermal expansion, uas txhais tau tias nws tsis nthuav dav lossis cog lus ntau nrog kev hloov pauv ntawm qhov kub thiab txias. Qhov no tseem ceeb heev hauv kev lag luam ua wafer, vim tias txhua qhov kev hloov pauv thermal tuaj yeem ua rau tsis sib haum ntawm cov tshuab thiab ua rau muaj teeb meem nrog kev ua wafer. Los ntawm kev siv lub hauv paus tshuab granite, nws ua kom cov tshuab tseem sib phim thiab qhov zoo ntawm kev ua wafer raug tswj hwm.
Qhov thib peb, granite muaj peev xwm damping siab heev, uas txhais tau tias nws tuaj yeem nqus tau kev co thiab tiv thaiv lawv kom tsis txhob cuam tshuam rau cov khoom siv hauv tshuab. Kev co tuaj yeem ua rau puas tsuaj rau cov khoom siv ua wafer, ua rau kev kho kim thiab lub sijhawm tsis ua haujlwm. Los ntawm kev siv lub hauv paus tshuab granite, nws txo qhov kev pheej hmoo ntawm kev puas tsuaj ntsig txog kev co thiab ua kom lub tshuab siv tau ntev.
Qhov thib plaub, granite yog cov khoom siv tsis muaj hlau nplaum, ua rau nws tsim nyog rau cov ntawv thov uas kev cuam tshuam hlau nplaum yuav ua rau muaj teeb meem, xws li hauv kev lag luam semiconductor. Qhov no ua kom ntseeg tau tias cov tshuab tsis cuam tshuam rau cov txheej txheem yooj yim uas koom nrog kev tsim cov khoom wafer.
Thaum kawg, granite yog ib yam khoom siv uas tuab thiab tawv heev, ua rau nws tiv taus kev hnav thiab rhuav piv rau lwm yam khoom siv xws li hlau thiab hlau cam khwb cia. Qhov no txhais tau tias lub hauv paus tshuab granite ruaj khov dua thiab xav tau kev saib xyuas tsawg dua, ua rau nws ua haujlwm tau ntev thiab txhim khu kev qha.
Xaus lus, qhov zoo ntawm kev siv granite tshuab puag rau cov khoom ua wafer tsis tuaj yeem hais dhau lawm. Nws qhov ruaj khov, qhov tseeb, tiv taus kev hloov pauv thermal, muaj peev xwm damping, cov khoom tsis yog hlau nplaum, thiab kev ua haujlwm ntev ua rau nws yog qhov kev xaiv zoo rau cov kev xav tau nyuaj ntawm kev ua wafer. Kev siv granite tshuab puag yuav tsis muaj qhov tsis ntseeg tau pab txhawb kev lag luam los ntawm kev txhim kho qhov zoo ntawm cov khoom wafer thiab txo cov nqi khiav lag luam.
