Dab tsi yog qhov sib txawv ntawm kev ua tau zoo ntawm cov khoom siv granite hauv cov khoom siv hluav taws xob semiconductor nyob rau lwm qhov chaw ib puag ncig?

Granite yog cov khoom siv uas nquag siv hauv cov khoom siv ntawm cov khoom siv hauv cov khoom siv semiconductor. Cov ntawv no, feem ntau nyob rau hauv daim ntawv ntawm chucks thiab muab lub zog ruaj khov rau kev tsiv thiab muab cov semiconductor wafers rau ntau theem ntawm cov txheej txheem tsim khoom. Cov kev ua tau zoo thiab kev ntseeg tau ntawm cov granite no yog cuam tshuam los ntawm ntau yam ntawm ntau yam, suav nrog ib puag ncig uas lawv tau siv.

Ib qho ntawm qhov tseem ceeb tshaj plaws uas cuam tshuam nrog cov khoom siv sliciconductor hauv cov cuab yeej kub. Granite muaj cov coefficient ntawm thermal nthuav, uas txhais tau hais tias nws tuaj yeem tiv thaiv ntau yam kub tsis muaj kev ntaus siab lossis tawg. Txawm li cas los xij, kev hloov pauv kub heev tuaj yeem ua rau muaj kev ntxhov siab nyob rau hauv cov khoom siv, ua rau kev tawg lossis delamination ntawm nto. Ib qho ntxiv, raug mob rau lub sijhawm kub rau lub sijhawm ntev tuaj yeem ua rau cov khoom siv kom muag muag, ua rau nws muaj kev phom sij thiab hnav.

Cov av noo yog qhov tseem ceeb ib puag ncig uas cuam tshuam rau kev ua tau zoo ntawm granite nyob rau hauv cov khoom siv semiconductor. Cov huab cua siab yuav ua rau noo noo kom pom mus rau hauv cov npoo av ntxig ntawm cov granite, ua rau delamination lossis tawg. Tsis tas li ntawd, noo noo tuaj yeem ua rau hluav taws xob luv, uas tuaj yeem ua rau cov hluav taws xob tsis zoo, cov khoom siv hluav taws xob ua kom zoo nkauj uas tau ua tiav ntawm cov npoo granite. Txhawm rau tiv thaiv cov teeb meem no, nws yog ib qho tseem ceeb kom ua kom qhuav ib puag ncig thaum lub sij hawm semiconductor cov txheej txheem raug.

Tshuaj lom neeg raug yog ib qho kev xav tseem ceeb thaum siv cov khoom siv granite hauv cov khoom siv semiconductor. Granite feem ntau tiv taus ntau yam tshuaj lom neeg, tab sis cov kuab tshuaj thiab cov kua qaub tuaj yeem ua rau puas tsuaj rau nws nto. Cov tshuaj lom neeg tu kom zoo li cov dej cawv ooprophlluoric lossis hydrofluoric acid tuaj yeem errode granite rougness thiab poob siab kawg. Txhawm rau zam cov teeb meem no, kev saib xyuas yuav tsum raug coj thaum xaiv cov neeg sawv cev tu thiab kom tiv thaiv kev puas tsuaj rau kev ua phem rau kev ua phem.

Lwm qhov chaw ib puag ncig uas cuam tshuam kev ua tau zoo ntawm granite yog kev co. Kev ua kom muaj cov micrracks nyob rau hauv cov av granite, ua rau kev cuam tshuam ntawm lub tiaj tiaj. Txhawm rau txo qis kev co, nws yog qhov tseem ceeb rau kev ua raws cov kauj ruam tsim nyog xws li txhim kho kev co tshuab thiab tsis txhob txav tsis tsim nyog ntawm cov khoom lag luam granite.

Hauv kev xaus, kev ua yeeb yam ntawm cov khoom siv hluav taws xob granite yog cuam tshuam nrog ntau yam ntawm ib puag ncig, av noo, tshuaj lom neeg siv tshuaj, thiab kev co. Los ntawm kev siv cov kev ntsuas tsim nyog kom txo qis cov laj thawj no, cov tuam txhab tuaj yeem ntseeg tau qhov kev ntseeg tau thiab ntev ntawm cov khoom siv slicionductor hauv cov khoom siv semiconductor. Nrog ceev faj rau ib puag ncig cov khoom siv thiab kev kho kom raug, cov cheebtsam zoo yuav txuas ntxiv mus ua ib lub luag haujlwm tseem ceeb hauv kev lag luam semiconduct.
