Granite Cheebtsam tau siv dav hauv cov txheej txheem tsim khoom semiconductor vim lawv cov yam ntxwv zoo heev xws li kev ua tiav saum npoo, siab tawv, thiab kev co zoo heev.Granite Cheebtsam yog qhov tseem ceeb rau cov khoom siv semiconductor fabrication, suav nrog cov tshuab lithography, polishing tshuab, thiab cov tshuab ntsuas ntsuas raws li lawv muab qhov tseeb qhov chaw thiab kev ruaj ntseg thaum lub sijhawm tsim khoom.Txawm hais tias txhua qhov zoo ntawm kev siv cov khoom siv granite, lawv kuj muaj qhov tsis xws luag.Nyob rau hauv tsab xov xwm no, peb yuav tham txog qhov tsis xws luag ntawm granite Cheebtsam rau semiconductor manufacturing txheej txheem khoom.
Ua ntej, granite Cheebtsam muaj lub siab thermal expansion coefficient.Nws txhais tau hais tias lawv nthuav dav heev nyob rau hauv thermal stress, uas yuav ua rau muaj teeb meem thaum lub sij hawm tsim khoom.Cov txheej txheem tsim khoom semiconductor yuav tsum muaj qhov tseeb thiab qhov tseeb qhov tseeb uas tuaj yeem cuam tshuam vim kev ntxhov siab thermal.Piv txwv li, silicon wafer deformation vim thermal expansion yuav ua rau muaj teeb meem kev sib raug zoo thaum lub sij hawm lithography, uas tuaj yeem cuam tshuam qhov zoo ntawm cov khoom siv semiconductor.
Qhov thib ob, cov khoom siv granite muaj qhov tsis xws luag uas tuaj yeem ua rau lub tshuab nqus tsev vacuum hauv cov txheej txheem tsim khoom semiconductor.Lub xub ntiag ntawm huab cua lossis lwm yam roj hauv lub cev tuaj yeem ua rau muaj kab mob ntawm lub wafer nto, ua rau muaj qhov tsis xws luag tuaj yeem cuam tshuam rau cov khoom siv semiconductor kev ua haujlwm.Cov pa roj tsis zoo xws li argon thiab helium tuaj yeem nkag mus rau hauv cov khoom ntxhib granite thiab tsim cov npuas roj uas tuaj yeem cuam tshuam nrog lub tshuab nqus tsev txoj kev ncaj ncees.
Thib peb, granite Cheebtsam muaj microfractures uas tuaj yeem cuam tshuam nrog cov txheej txheem tsim khoom.Granite yog cov khoom siv tawv tawv uas tuaj yeem tsim microfractures nyob rau lub sijhawm, tshwj xeeb tshaj yog thaum raug kev ntxhov siab tas li.Lub xub ntiag ntawm microfractures tuaj yeem ua rau qhov tsis txaus ntseeg, ua rau muaj teeb meem tseem ceeb thaum lub sijhawm tsim khoom, xws li lithography alignment lossis wafer polishing.
Plaub, granite Cheebtsam muaj qhov yooj yooj yim.Cov txheej txheem tsim khoom semiconductor xav tau cov cuab yeej hloov tau yooj yim uas tuaj yeem ua raws li cov txheej txheem sib txawv.Txawm li cas los xij, cov khoom siv granite yog nruj thiab tsis tuaj yeem hloov mus rau cov txheej txheem sib txawv.Yog li ntawd, ib qho kev hloov pauv hauv cov txheej txheem tsim khoom yuav tsum tau tshem tawm lossis hloov cov khoom siv granite, ua rau poob qis thiab cuam tshuam rau kev tsim khoom.
Thib tsib, cov khoom siv granite xav tau tshwj xeeb tuav thiab kev thauj mus los vim lawv qhov hnyav thiab tsis muaj zog.Granite yog cov khoom hnyav thiab hnyav uas yuav tsum tau siv cov cuab yeej tshwj xeeb xws li cranes thiab lifters.Tsis tas li ntawd, cov khoom siv granite xav tau kev ntim khoom zoo thiab kev thauj mus los los tiv thaiv kev puas tsuaj thaum lub sijhawm xa khoom, ua rau cov nqi ntxiv thiab sijhawm.
Hauv kev xaus, cov khoom siv granite muaj qee qhov tsis zoo uas tuaj yeem cuam tshuam rau cov txheej txheem tsim khoom semiconductor 'zoo thiab tsim khoom.Cov kev tsis zoo no tuaj yeem txo qis los ntawm kev ua tib zoo tuav thiab saib xyuas cov khoom siv granite, suav nrog kev tshuaj xyuas ib ntus rau microfractures thiab porosity defects, kev tu kom zoo los tiv thaiv kev sib kis, thiab ceev faj thaum thauj.Txawm hais tias muaj qhov tsis xws luag, cov khoom siv granite tseem yog ib feem tseem ceeb ntawm cov txheej txheem tsim khoom semiconductor vim lawv qhov ua tiav zoo tshaj plaws, siab tawv, thiab kev co zoo heev.
