Wafer ua khoom siv yog ib feem tseem ceeb ntawm cov txheej txheem tsim khoom semiconductor.Cov tshuab no yog tsim los ntawm ntau yam khoom, nrog rau cov khoom siv granite.Granite yog ib qho khoom siv zoo tshaj plaws rau cov khoom siv no vim nws txoj kev ruaj ntseg zoo thiab ua haujlwm ntev.Txawm li cas los xij, zoo li lwm yam khoom siv, cov khoom siv granite yog qhov ua rau muaj qhov tsis xws luag uas yuav cuam tshuam rau kev ua haujlwm thiab kev ua haujlwm ntawm cov khoom siv wafer.Hauv tsab xov xwm no, peb yuav tham txog qee qhov tsis xws luag ntawm granite Cheebtsam hauv wafer ua khoom siv.
1. Kev tawg:
Ib qho ntawm feem ntau tsis xws luag hauv granite Cheebtsam yog tawg.Cov kab nrib pleb no tuaj yeem tshwm sim los ntawm ntau yam, suav nrog kev hloov pauv ntawm qhov kub thiab txias, kev ntxhov siab ntawm kev siv tshuab, kev tuav tsis raug, thiab kev saib xyuas tsis txaus.Kev tawg tuaj yeem ua rau tsis zoo ntawm cov qauv ntawm cov khoom siv granite, ua rau lawv muaj kev cuam tshuam ntau dua rau kev ua tsis tiav.Ntxiv mus, cov kab nrib pleb tuaj yeem ua qhov chaw muaj peev xwm rau kev ntxhov siab, ua rau muaj kev puas tsuaj ntxiv.
2. Txiav:
Lwm qhov tsis xws luag uas yuav tshwm sim hauv cov khoom siv granite yog chipping.Chiping tuaj yeem tshwm sim los ntawm ntau yam xwm txheej xws li kev sib tsoo, kev tuav tsis raug, lossis hnav thiab tsim kua muag.Chiped granite Cheebtsam tej zaum yuav muaj ib tug ntxhib nto thiab cov npoo tsis sib xws uas tuaj yeem ua rau cov wafers puas thaum lub sijhawm tsim khoom.Tsis tas li ntawd, chipping tuaj yeem cuam tshuam qhov tseeb qhov tseeb ntawm cov khoom, ua rau cov khoom siv tsis raug thiab kev tsim khoom poob.
3. Hnav thiab tsim kua muag:
Kev siv tsis tu ncua thiab tsis tu ncua ntawm cov khoom siv abrasive tuaj yeem ua rau hnav thiab tsim kua muag ntawm cov khoom siv granite.Nyob rau tib lub sijhawm, hnav thiab tsim kua muag yuav ua rau txo qis hauv kev ua haujlwm thiab kev ua haujlwm ntawm cov khoom siv wafer.Tsis tas li ntawd, nws yuav ua rau muaj kev nce nqi hauv kev saib xyuas thiab cov nqi hloov pauv.
4. Kev tsis sib haum xeeb:
Granite Cheebtsam, xws li wafer ua cov rooj thiab chucks, yuav tsum tau ua raws li qhov tseeb kom tswj tau qhov yuav tsum tau muaj tseeb thiab sib xws hauv cov txheej txheem tsim khoom.Txawm li cas los xij, misalignment tuaj yeem tshwm sim vim muaj ntau yam laj thawj, xws li kev teeb tsa tsis raug, cuam tshuam rau kev vibrations, lossis cov khoom puas tsuaj.Misalignment tuaj yeem ua rau qhov tsis raug ntawm kev tsim cov wafers, uas tuaj yeem ua rau cov khoom tsis raug.
5. Corrosion:
Granite yog cov khoom siv tsis muaj zog uas tiv taus ntau yam tshuaj thiab cov kuab tshuaj.Txawm li cas los xij, kev cuam tshuam ntev rau cov tshuaj lom neeg, xws li acids lossis alkalis, tuaj yeem ua rau corrosion ntawm granite Cheebtsam.Corrosion tuaj yeem ua rau nto pitting, discoloration, los yog poob ntawm qhov tseeb.
Xaus:
Granite Cheebtsam yog qhov tseem ceeb rau kev ruaj ntseg thiab kev ntseeg siab ntawm cov khoom siv wafer.Txawm li cas los xij, qhov tsis xws luag xws li tawg, chipping, hnav thiab tsim kua muag, misalignment, thiab corrosion tuaj yeem cuam tshuam kev ua haujlwm thiab kev ua haujlwm ntawm cov khoom no.Kev saib xyuas kom zoo, tuav kom txaus, thiab kev tshuaj xyuas tsis tu ncua tuaj yeem pab tiv thaiv thiab txo qhov cuam tshuam ntawm cov teeb meem no.Los ntawm kev daws cov teeb meem no kom zoo, peb tuaj yeem ua kom muaj kev ua haujlwm txuas ntxiv ntawm cov khoom tseem ceeb no thiab tswj xyuas qhov zoo thiab qhov tseeb ntawm cov khoom siv wafer.
