Granite yog ib qho kev xaiv nrov rau lub txaj ntawm cov khoom siv semiconductor vim nws cov thermal stability zoo heev thiab txhua yam muaj zog.Lub thermal expansion coefficient (TEC) ntawm granite yog ib qho tseem ceeb ntawm lub cev khoom uas txiav txim siab nws qhov tsim nyog rau kev siv hauv cov ntawv thov no.
Lub thermal expansion coefficient ntawm granite yog kwv yees li ntawm 4.5 - 6.5 x 10^-6 / K.Qhov no txhais tau hais tias rau txhua qhov kub ntawm qhov kub thiab txias, lub txaj granite yuav nthuav dav los ntawm tus nqi no.Thaum qhov no yuav zoo li hloov me me, nws tuaj yeem ua rau muaj teeb meem loj hauv cov khoom siv semiconductor yog tias tsis suav nrog.
Cov khoom siv semiconductor yog qhov nkag siab zoo rau kev hloov pauv kub, thiab qee qhov kev hloov pauv me ntsis hauv qhov kub thiab txias tuaj yeem cuam tshuam rau lawv txoj haujlwm.Yog li, nws yog ib qho tseem ceeb uas TEC ntawm cov khoom siv hauv cov khoom siv no yog qhov tsawg thiab kwv yees tau.Granite tsis tshua muaj TEC tso cai rau kom ruaj khov thiab sib xws thaum tshav kub kub dissipation los ntawm lub cuab yeej, xyuas kom meej tias qhov kub thiab txias nyob rau hauv qhov xav tau ntau yam.Qhov no yog qhov tseem ceeb vim tias cov cua kub ntau dhau tuaj yeem ua rau cov khoom siv semiconductor puas thiab ua rau nws lub neej luv.
Lwm yam uas ua rau granite yog ib qho khoom txaus nyiam rau lub txaj ntawm cov khoom siv semiconductor yog nws lub zog txhua yam.Lub peev xwm ntawm lub txaj granite kom tiv taus ntau qhov kev ntxhov siab thiab nyob ruaj khov yog qhov tseem ceeb vim tias cov khoom siv semiconductor feem ntau raug rau lub cev vibrations thiab shocks.Qhov sib txawv ntawm kev nthuav dav thiab kev cog lus ntawm cov ntaub ntawv vim qhov kub thiab txias tuaj yeem ua rau muaj kev ntxhov siab hauv lub cuab yeej, thiab granite lub peev xwm los tswj nws cov duab raws li cov xwm txheej no txo qhov kev pheej hmoo ntawm kev puas tsuaj thiab tsis ua haujlwm.
Hauv kev xaus, thermal expansion coefficient ntawm granite txaj plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov khoom siv semiconductor.Los ntawm kev xaiv cov khoom siv nrog TEC qis, zoo li granite, cov tuam txhab tsim cov khoom siv chips tuaj yeem ua kom ruaj khov thermal ua haujlwm thiab txhim khu kev qha ntawm cov khoom siv no.Qhov no yog vim li cas granite tau dav siv los ua cov khoom siv hauv txaj hauv kev lag luam semiconductor, thiab nws qhov tseem ceeb tsis tuaj yeem hais dhau los thaum nws los ua kom ntseeg tau qhov zoo thiab kev ua haujlwm ntev ntawm cov khoom siv no.
