Cov cuab yeej thev naus laus zis ntawm cov av granite hauv cov khoom siv semiconductor?

Nrog kev loj hlob ntawm thev naus laus zis, kev siv cov khoom siv granite hauv cov cuab yeej ua semiconductor tau ua ntau dua thiab nrov dua. Granite yog qhov kev xaiv nrov rau siv nyob rau hauv kev ua siv thev naus laus zis ntawm cov cuab yeej cuab tam uas yog nws cov txiaj ntsig ntau. Granite yog ib qho nyuaj tshaj plaws thiab cov ntaub ntawv ruaj khov tshaj plaws uas muaj cov uas ua rau nws zoo rau kev siv hauv cov semiconductor tsim kev lag luam. Nws yog ib tug zoo tshaj plaws thermal thiab muaj qhov tsawg heev coefficient ntawm thermal expansion uas ua rau nws zoo meej rau kev siv hauv cov ntawv thov kub siab.

Cov thev naus laus zis ntawm cov pob zeb granite hauv cov khoom siv semiconductor koom nrog ntau cov txheej txheem thiab cov txheej txheem. Cov kauj ruam tseem ceeb yog polishing, etching, thiab tu cov granite nto. Hom kev ua lag luam siv yuav tsum muaj nyob ntawm daim ntawv thov thiab hom granite raug siv.

Polishing yog ib qho tseem ceeb ntawm kev ua cov khoom lag luam granite hauv cov khoom siv semiconductor. Polishing rau saum npoo ntawm granite mus rau qib siab ntawm smoothness pab kom ntseeg tau tias cov wafer tsis puas thaum lub sijhawm ua. Qhov no txo ​​qis kev pheej hmoo ntawm kev paug los ntawm cov lus lossis khawb rau saum npoo ntawm wafer. Polishing tuaj yeem ua tiav los ntawm ntau cov hau kev xws li kev siv zog txhua yam, tshuaj lom neeg polishing, thiab electrochemical Polishing, thiab lwm yam.

Etching yog lwm qhov tseem ceeb ntawm kev ua cov khoom lag luam granite hauv cov khoom siv semiconductor. Etching yog siv los tsim cov qauv xav tau ntawm cov npoo av ntawm cov granite. Cov qauv siv nyob rau hauv kev tsim khoom thiab kev ua ntawm semiconductor wafers. Muaj ob peb txoj hauv kev los ua cov etchma etching, suav nrog kev siv ntshav etching, ntub tshuaj etching, thiab qhuav tshuaj tsuag etching, thiab lwm tus. Hom txheej txheem etching siv yuav nyob ntawm cov khoom siv thiab cov qauv xav tau.

Ntxuav lub granite nto kuj tseem ceeb heev. Txheej txheem ntxuav yog qhov tsim nyog los tshem tawm cov kev paug los ntawm saum npoo av, xws li cov lus impurities uas tuaj yeem cuam tshuam nrog cov txheej txheem sib raug zoo. Kev ntxuav tu tau tuaj yeem ua tiav siv ntau txoj hauv kev xws li kev ntxuav ultrasonic, tshuaj ntxuav tshuaj, lossis ntshav ntxuav.

Hauv kev xaus, kev ua haujlwm ntawm cov tshuab granite hauv cov cuab yeej ua haujlwm semiconduct plays lub luag haujlwm tseem ceeb hauv cov txheej txheem kev tsim khoom. Kev siv cov av granite pab txhim kho kom zoo thiab muaj kev ntseeg siab ntawm cov khoom kawg. Cov thev naus laus zis koom nrog polishing, etching, thiab tu cov granite nto. Muaj ntau txoj hauv kev rau txhua kauj ruam, thiab hom kev siv tshuab ua siv yuav nyob ntawm cov khoom siv thiab cov yam xav tau. Los ntawm kev siv cov thev naus laus zis ua tau zoo, cov txheej txheem tsim khoom lag luam tuaj yeem ua tau zoo dua, txhim khu kev qha, thiab raug nqi.
