Dab tsi yog qhov kev siv tshuab ntawm granite qhov hauv cov khoom siv semiconductor?

Nrog kev loj hlob ntawm kev siv tshuab, kev siv cov khoom siv granite hauv cov khoom siv semiconductor tau dhau los ua neeg nyiam.Granite yog ib qho kev xaiv nrov rau kev siv cov tshuab ua cov khoom siv semiconductor vim nws cov txiaj ntsig ntau.Granite yog ib qho ntawm cov khoom siv tawv thiab ruaj khov tshaj plaws uas ua rau nws zoo tagnrho rau kev siv hauv kev lag luam semiconductor.Nws yog ib qho zoo heev thermal conductor thiab muaj ib tug tsawg coefficient ntawm thermal expansion uas ua rau nws zoo meej rau siv nyob rau hauv high kub daim ntaub ntawv.

Kev siv thev naus laus zis ntawm granite qhov chaw hauv cov khoom siv semiconductor suav nrog ntau yam txheej txheem thiab txheej txheem.Cov kauj ruam tseem ceeb yog polishing, etching, thiab tu cov granite nto.Hom kev siv tshuab siv yuav nyob ntawm daim ntawv thov thiab hom granite siv.

Polishing yog ib qho tseem ceeb ntawm kev ua cov khoom granite hauv cov khoom siv semiconductor.Polishing nto ntawm granite mus rau qib siab ntawm smoothness pab kom paub tseeb tias lub wafer tsis puas thaum ua.Qhov no yuav txo tau txoj kev kis kab mob los ntawm cov khoom los yog khawb ntawm qhov chaw ntawm wafer.Polishing tuaj yeem ua tiav los ntawm ntau txoj hauv kev xws li tshuab polishing, tshuaj polishing, thiab electrochemical polishing, thiab lwm yam.

Etching yog lwm qhov tseem ceeb ntawm kev ua cov khoom granite hauv cov khoom siv semiconductor.Etching yog siv los tsim cov qauv xav tau ntawm qhov chaw ntawm granite.Cov qauv yog siv nyob rau hauv kev tsim thiab ua ntawm semiconductor wafers.Muaj ntau ntau txoj hauv kev los ua etching, suav nrog plasma etching, ntub tshuaj etching, thiab qhuav tshuaj etching, thiab lwm yam.Hom etching txheej txheem siv yuav nyob ntawm seb cov khoom siv thiab cov qauv xav tau.

Kev ntxuav ntawm granite nto kuj tseem ceeb heev.Cov txheej txheem ntxuav yog tsim nyog los tshem tawm cov kab mob ntawm qhov chaw, xws li cov khoom thiab lwm yam impurities uas yuav cuam tshuam rau cov txheej txheem tsim khoom semiconductor.Kev ntxuav tuaj yeem ua tiav siv ntau txoj hauv kev xws li ntxuav ultrasonic, tshuaj ntxuav, lossis ntxuav ntshav, thiab lwm yam.

Hauv kev xaus, kev siv thev naus laus zis ntawm granite qhov chaw hauv cov khoom siv semiconductor plays lub luag haujlwm tseem ceeb hauv cov txheej txheem tsim khoom semiconductor.Kev siv cov khoom siv granite pab txhim kho qhov zoo thiab kev ntseeg siab ntawm cov khoom kawg.Kev siv thev naus laus zis suav nrog polishing, etching, thiab tu cov granite nto.Muaj ntau txoj hauv kev muaj rau txhua kauj ruam, thiab hom kev siv tshuab siv yuav nyob ntawm cov khoom siv thiab cov qauv xav tau.Los ntawm kev siv cov thev naus laus zis thev naus laus zis, cov txheej txheem tsim khoom semiconductor tuaj yeem ua kom muaj txiaj ntsig zoo dua, txhim khu kev qha, thiab muaj txiaj ntsig zoo.
