Kev lag luam semiconductor yog ib feem tseem ceeb ntawm thev naus laus zis niaj hnub no. Nws tsim cov khoom siv hluav taws xob xws li microchips thiab transistors uas muab zog rau ntau yam khoom siv hluav taws xob. Cov txheej txheem tsim cov khoom no xav tau qib siab ntawm kev ua haujlwm kom ntseeg tau tias muaj kev ua tau zoo thiab kev ntseeg siab.
Ib qho tseem ceeb ntawm cov khoom siv tsim khoom semiconductor yog lub hauv paus. Lub hauv paus ua lub hauv paus uas lub tshuab tau tsim, thiab nws muab kev ruaj khov thiab kev txhawb nqa rau ntau yam khoom uas ua rau cov khoom siv. Tau ntau xyoo, granite tau yog cov khoom siv xaiv rau cov khoom siv semiconductor vim nws cov khoom zoo dua.
Granite yog ib hom pob zeb uas tsim los ntawm kev sib xyaw ua ke ntawm cov zaub mov xws li feldspar, quartz, thiab mica. Nws paub txog nws qhov ruaj khov, ruaj khov, thiab co-efficient qis ntawm thermal expansion. Cov yam ntxwv no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau lub hauv paus khoom siv semiconductor.
Qhov kev ua haujlwm raug ntawm lub hauv paus granite yog qhov tseem ceeb rau qhov kev ua haujlwm raug ntawm cov khoom siv semiconductor. Lub hauv paus yuav tsum tau ua kom raug raws li qhov kev kam rau siab kom ntseeg tau tias ntau yam khoom sib dhos zoo. Qhov kev ua haujlwm raug ntawm cov txheej txheem ua haujlwm cuam tshuam rau qhov tseeb ntawm cov khoom siv, uas ua rau muaj kev cuam tshuam rau qhov zoo thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob uas tau tsim tawm.
Granite yog ib yam khoom siv tawv heev, ua rau nws nyuaj rau tshuab. Cov txheej txheem machining xav tau cov khoom siv tshwj xeeb thiab cov kws tshaj lij uas muaj kev txawj ntse heev. Txawm li cas los xij, qhov kev siv zog no tsim nyog vim tias qhov tseeb ntawm cov khoom siv yog sib npaug ncaj qha rau qhov tseeb ntawm cov txheej txheem machining.
Lwm qhov zoo ntawm kev siv lub hauv paus granite rau cov khoom siv semiconductor yog nws lub peev xwm los muab kev ruaj khov thermal zoo heev. Qhov kev ua haujlwm siab thiab kev kam rau siab ntawm cov khoom siv semiconductor txhais tau tias txawm tias qhov kev hloov pauv me me hauv qhov kub thiab txias tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub tshuab. Qhov coefficient qis ntawm thermal expansion ntawm granite txhais tau tias nws tsis tshua muaj peev xwm nthuav dav lossis cog lus vim qhov kub thiab txias hloov pauv, uas pab tswj qhov tseeb ntawm lub tshuab.
Hauv kev xaus lus, kev siv lub hauv paus granite rau cov khoom siv semiconductor yog qhov tseem ceeb rau qhov tseeb, qhov tseeb, thiab kev ntseeg siab ntawm cov khoom siv. Qhov tseeb ntawm lub hauv paus cuam tshuam ncaj qha rau qhov zoo ntawm cov khoom siv hluav taws xob uas tau tsim tawm. Qhov ruaj khov thiab ruaj khov ntawm lub hauv paus granite pab tswj qhov tseeb ntawm cov khoom siv thiab txo qhov cuam tshuam ntawm kev hloov pauv kub. Raws li thev naus laus zis txuas ntxiv mus, qhov tseem ceeb ntawm qhov tseeb hauv kev tsim khoom semiconductor tsuas yog txuas ntxiv nce ntxiv, uas txhais tau tias qhov tseem ceeb ntawm lub hauv paus granite-machined precision yuav tsuas yog qhov tseem ceeb dua.
