Granite tau siv dav hauv kev lag luam semiconductor rau kev tsim cov khoom siv precision, suav nrog cov khoom siv ua wafer. Qhov no yog vim cov khoom siv zoo heev xws li kev ruaj khov siab, kev nthuav dav thermal qis, thiab kev co siab. Nws muab qhov chaw ruaj khov thiab tiaj tus, uas yog qhov tseem ceeb hauv kev tsim cov hluav taws xob me me ntawm wafers.
Thaum siv granite hauv cov khoom siv ua wafer, nws yog ib qho tseem ceeb uas yuav tsum ua tib zoo saib xyuas kom zoo kom ntseeg tau tias muaj txiaj ntsig zoo tshaj plaws thiab siv tau ntev. Nov yog qee cov lus qhia rau kev siv thiab tswj hwm granite kom raug.
1. Kev tuav thiab kev teeb tsa kom zoo
Granite yog ib yam khoom hnyav thiab tawg yooj yim heev uas yuav tsum tau tuav thiab teeb tsa kom zoo. Nws yog ib qho tseem ceeb kom paub tseeb tias qhov chaw tau sib npaug ua ntej teeb tsa. Txhua qhov tsis sib xws tuaj yeem ua rau puas tsuaj rau cov khoom siv, uas tuaj yeem cuam tshuam rau qhov zoo ntawm cov wafers tsim tawm. Granite yuav tsum tau ua tib zoo tuav thiab yuav tsum tau thauj thiab teeb tsa nrog kev pab los ntawm cov khoom siv tshwj xeeb.
2. Kev ntxuav tas li
Cov khoom siv ua wafer uas siv granite yuav tsum tau ntxuav tas li kom tiv thaiv kev sib sau ua ke ntawm cov khib nyiab thiab av qias neeg ntawm qhov chaw. Kev sib sau ua ke ntawm cov khib nyiab tuaj yeem ua rau khawb lossis ua rau muaj kab nrib pleb, uas tuaj yeem cuam tshuam rau qhov zoo ntawm cov wafer tsim tawm. Ib daim ntaub mos mos thiab cov tshuaj ntxuav tes mos mos tuaj yeem txaus rau kev ntxuav cov granite nto. Yuav tsum zam cov tshuaj ntxuav thiab tshuaj lom neeg hnyav vim tias lawv tuaj yeem ua rau puas tsuaj rau qhov chaw.
3. Kev saib xyuas tiv thaiv
Kev saib xyuas ua ntej yog qhov tseem ceeb kom ntseeg tau tias cov khoom siv ua wafer ua haujlwm tau zoo tshaj plaws. Cov khoom siv thiab qhov chaw granite yuav tsum tau kuaj xyuas tsis tu ncua, thiab txhua yam cim ntawm kev puas tsuaj yuav tsum tau daws tam sim ntawd. Qhov no tuaj yeem pab nrhiav pom cov teeb meem thaum ntxov thiab tiv thaiv lawv kom tsis txhob tshwm sim rau hauv cov teeb meem loj dua uas kim dua los kho.
4. Tsis txhob siv cua sov los ua kom lub cev kub
Granite rhiab heev rau qhov kub thiab txias hloov pauv, thiab yuav tsum tsis txhob muaj kev hloov pauv kub sai sai. Kev hloov pauv kub sai sai tuaj yeem ua rau granite nthuav dav thiab cog lus, ua rau tawg lossis warping ntawm qhov chaw. Kev tswj qhov kub thiab txias ruaj khov hauv chav ua haujlwm tuaj yeem pab tiv thaiv qhov no kom tsis txhob tshwm sim. Tsis tas li ntawd, nws yog ib qho tseem ceeb kom tsis txhob muab cov khoom kub tso rau ntawm qhov chaw granite kom tiv thaiv kev poob siab thermal.
Xaus lus, granite yog ib yam khoom siv feem ntau siv rau hauv cov khoom siv ua wafer vim nws cov khoom zoo tshaj plaws uas pab txhawb rau kev tsim cov wafers zoo. Txhawm rau kom ntseeg tau tias muaj kev ua haujlwm zoo tshaj plaws thiab lub neej ntev, kev tuav kom zoo, kev ntxuav tas li, kev saib xyuas tiv thaiv, thiab kev zam kev hloov pauv thermal yog qhov tseem ceeb. Cov kev coj ua no tuaj yeem pab ua kom cov khoom siv zoo heev, ua rau muaj kev tsim khoom zoo tshaj plaws thiab cov wafers zoo.
