Cov coefficient thermal expansion ntawm granite txaj yog dab tsi? Qhov no tseem ceeb npaum li cas rau cov khoom siv semiconductor?

Granite yog ib qho kev xaiv nrov rau lub txaj ntawm cov khoom siv semiconductor vim nws qhov kev ruaj khov thermal zoo heev thiab lub zog kho tshuab. Tus coefficient thermal expansion (TEC) ntawm granite yog ib qho khoom siv tseem ceeb uas txiav txim siab nws qhov kev tsim nyog rau kev siv hauv cov ntawv thov no.

Tus coefficient ntawm thermal expansion ntawm granite yog kwv yees li ntawm 4.5 - 6.5 x 10^-6/K. Qhov no txhais tau tias rau txhua qhov degree Celsius nce hauv qhov kub, lub txaj granite yuav nthuav dav los ntawm qhov ntau no. Txawm hais tias qhov no yuav zoo li yog qhov kev hloov pauv me me, nws tuaj yeem ua rau muaj teeb meem loj hauv cov khoom siv semiconductor yog tias tsis tau suav nrog kom raug.

Cov khoom siv semiconductor muaj kev cuam tshuam loj heev rau qhov kub thiab txias hloov pauv, thiab txhua qhov kev hloov pauv me me ntawm qhov kub thiab txias tuaj yeem cuam tshuam rau lawv cov kev ua tau zoo. Yog li ntawd, nws yog qhov tseem ceeb uas TEC ntawm cov ntaub ntawv siv hauv cov khoom siv no qis thiab kwv yees tau. Granite's TEC qis tso cai rau kev kub hnyiab ruaj khov thiab sib xws los ntawm lub cuab yeej, kom ntseeg tau tias qhov kub thiab txias tseem nyob hauv qhov ntau yam xav tau. Qhov no yog qhov tseem ceeb vim tias kub dhau tuaj yeem ua rau cov khoom siv semiconductor puas tsuaj thiab ua rau nws lub neej luv dua.

Lwm yam uas ua rau granite yog ib yam khoom zoo rau lub txaj ntawm cov khoom siv semiconductor yog nws lub zog kho tshuab. Lub peev xwm ntawm lub txaj granite los tiv taus ntau qhov kev ntxhov siab thiab nyob ruaj khov yog qhov tseem ceeb vim tias cov khoom siv semiconductor feem ntau raug kev co thiab kev poob siab. Kev nthuav dav thiab kev sib txuas ntawm cov ntaub ntawv vim qhov kub thiab txias hloov pauv kuj tuaj yeem ua rau muaj kev ntxhov siab hauv lub cuab yeej, thiab granite lub peev xwm los tswj nws cov duab hauv qab cov xwm txheej no txo ​​qhov kev pheej hmoo ntawm kev puas tsuaj thiab kev ua tsis tiav.

Xaus lus, qhov coefficient ntawm thermal expansion ntawm granite txaj ua 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 chaw tsim khoom ntawm cov khoom siv ua chip tuaj yeem ua kom muaj kev ua haujlwm thermal ruaj khov thiab kev ua haujlwm txhim khu kev qha ntawm cov khoom siv no. Qhov no yog vim li cas granite siv dav ua cov khoom siv txaj hauv kev lag luam semiconductor, thiab nws qhov tseem ceeb tsis tuaj yeem overstated thaum nws los txog rau kev ua kom zoo thiab lub neej ntev ntawm cov khoom siv no.
