Granite yog cov khoom siv feem ntau hauv kev tsim cov khoom siv hauv cov khoom siv semiconductor.Cov khoom no, feem ntau nyob rau hauv daim ntawv ntawm chucks thiab pedestals, muab lub platform ruaj khov rau kev txav thiab tso cov khoom siv hluav taws xob semiconductor wafers nyob rau ntau theem ntawm kev tsim khoom.Kev ua tau zoo thiab kev ntseeg siab ntawm cov khoom siv granite no cuam tshuam los ntawm ntau yam, suav nrog ib puag ncig uas lawv siv.
Ib qho tseem ceeb tshaj plaws ntawm ib puag ncig uas cuam tshuam rau cov khoom siv granite hauv cov khoom siv semiconductor yog qhov kub thiab txias.Granite muaj cov coefficient tsawg ntawm thermal expansion, uas txhais tau hais tias nws tuaj yeem tiv taus ntau yam kub yam tsis muaj warping lossis tawg.Txawm li cas los xij, qhov kub thiab txias hloov pauv tuaj yeem ua rau muaj kev ntxhov siab hauv cov khoom, ua rau tawg lossis delamination ntawm qhov chaw.Tsis tas li ntawd, raug rau qhov kub thiab txias rau lub sijhawm ntev tuaj yeem ua rau cov khoom muag muag, ua rau nws raug deformation thiab hnav.
Cov av noo yog lwm qhov tseem ceeb ntawm ib puag ncig uas cuam tshuam rau kev ua haujlwm ntawm cov khoom siv granite hauv cov khoom siv semiconductor.Cov av noo siab tuaj yeem ua rau cov av noo nkag mus rau hauv qhov ntxeem tau ntawm granite, ua rau delamination lossis tawg.Tsis tas li ntawd, cov dej noo tuaj yeem ua rau cov hluav taws xob luv luv, uas tuaj yeem ua rau cov khoom siv hluav taws xob tsis zoo uas tau ua tiav ntawm granite nto.Txhawm rau tiv thaiv cov teeb meem no, nws yog ib qho tseem ceeb kom tswj tau qhov chaw qhuav thaum lub sij hawm tsim cov txheej txheem semiconductor.
Kev raug tshuaj lom neeg kuj tseem ceeb heev thaum siv cov khoom siv granite hauv cov khoom siv semiconductor.Granite feem ntau tiv taus cov tshuaj feem ntau, tab sis qee cov kuab tshuaj thiab cov kua qaub tuaj yeem ua rau puas tsuaj rau nws qhov chaw.Cov neeg ua haujlwm tu ib txwm xws li isopropyl cawv lossis hydrofluoric acid tuaj yeem etch lossis corrode granite nto, ua rau nto roughness thiab txo flatness.Txhawm rau zam cov teeb meem no, yuav tsum tau saib xyuas thaum xaiv cov tshuaj ntxuav thiab cov txheej txheem los tiv thaiv kev puas tsuaj tshuaj.
Lwm qhov chaw ib puag ncig uas cuam tshuam rau kev ua haujlwm ntawm cov khoom siv granite yog kev co.Kev vibrations tuaj yeem ua rau microcracks hauv granite nto, ua rau degradation ntawm qhov chaw tiaj tus.Txhawm rau txo qis kev vibration, nws yog ib qho tseem ceeb uas yuav tsum tau ua cov kauj ruam tsim nyog xws li txhim kho kev co kev sib cais thiab tsis txhob txav mus los ntawm cov khoom siv granite.
Hauv kev xaus, kev ua tau zoo ntawm cov khoom siv granite hauv cov khoom siv semiconductor cuam tshuam los ntawm ntau yam ib puag ncig xws li kub, av noo, tshuaj lom neeg, thiab kev co.Los ntawm kev siv cov kev ntsuas tsim nyog los txo qis qhov cuam tshuam rau cov xwm txheej no, cov tuam ntxhab tuaj yeem ua kom ntseeg tau thiab siv tau ntev ntawm cov khoom siv granite hauv cov khoom siv semiconductor.Ua tib zoo saib xyuas cov xwm txheej ib puag ncig thiab kev saib xyuas kom raug, cov khoom siv granite yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev lag luam semiconductor.
