Lub txaj granite yog ib qho ntawm cov ntaub ntawv siv ntau tshaj plaws hauv kev tsim cov khoom siv semiconductor siab. Nws yog pob zeb uas tsim los ntawm kev qeeb thiab khov ntawm magma tob hauv lub ntiaj teb lub plhaub. Ib qho tseem ceeb ntawm granite yog tias nws yog cov khoom siv tawv, ntom, thiab ruaj khov, uas ua rau nws zoo meej rau kev siv hauv kev tsim cov hauv paus tshuab thiab txaj.
Cov khoom tseem ceeb ntawm lub txaj granite muaj xws li feldspar, quartz, thiab mica. Feldspar yog ib pawg ntawm cov pob zeb uas feem ntau pom muaj nyob rau hauv granite. Nws yog cov pob zeb uas muaj ntau tshaj plaws hauv granite, thiab nws qhov muaj nyob rau hauv lub pob zeb ua rau nws muaj cov qauv ntxhib. Quartz yog lwm cov pob zeb uas pom muaj ntau hauv granite. Nws yog cov pob zeb tawv thiab tawg yooj yim uas tuaj yeem tiv taus qhov kub siab, ua rau nws zoo meej rau kev siv rau hauv cov ntawv thov siab. Mica, ntawm qhov tod tes, yog cov pob zeb mos uas tsim cov nplais nyias thiab yoog tau. Nws qhov muaj nyob rau hauv granite pab kom muaj kev ruaj khov thiab tiv thaiv kev tawg.
Kev siv cov txaj granite hauv cov khoom siv semiconductor muaj ntau yam zoo. Ua ntej, nws muab qhov chaw ruaj khov thiab tiaj tus rau cov semiconductor wafer so. Qhov no, ua rau muaj cov txheej txheem tsim khoom meej dua vim tias txhua qhov kev hloov pauv me me lossis kev hloov pauv ntawm qhov chaw ntawm lub txaj tuaj yeem ua rau muaj qhov yuam kev lossis kev ua haujlwm tsis zoo hauv cov khoom siv semiconductor. Qhov nyuaj ntawm lub txaj granite kuj txhais tau tias nws yuav tsis tshua muaj kev puas tsuaj lossis deformed dhau sijhawm, ua kom ntseeg tau tias cov khoom siv ruaj khov.
Lwm qhov zoo ntawm kev siv lub txaj granite hauv cov khoom siv semiconductor yog tias nws muaj cov coefficient thermal expansion qis. Qhov no txhais tau tias nws tuaj yeem tiv taus qhov kev hloov pauv ntawm qhov kub thiab txias yam tsis cuam tshuam rau kev ua haujlwm ntawm cov khoom siv semiconductor. Yog li ntawd, cov chaw tsim khoom semiconductor tuaj yeem ua cov txheej txheem uas xav tau qhov kub thiab txias siab yam tsis txhawj txog kev nthuav dav thermal lossis kev cog lus. Ntxiv mus, nws tiv thaiv kev loj hlob ntawm cov thermal gradients, uas tuaj yeem ua rau kev ua haujlwm ntawm cov khoom siv puas tsuaj.
Xaus lus
Xaus lus, kev siv cov txaj granite hauv cov khoom siv semiconductor tau hloov pauv kev lag luam, ua rau muaj kev tsim cov khoom siv ua haujlwm zoo dua thiab meej dua. Cov khoom tseem ceeb ntawm cov txaj granite, suav nrog feldspar, quartz, thiab mica, ua kom lub txaj ruaj khov, ruaj khov, thiab muaj cov coefficient thermal expansion qis. Qhov no ua rau nws zoo tagnrho rau kev tsim cov tshuab uas xav tau kev ua haujlwm siab, xws li cov uas siv hauv kev tsim cov khoom siv semiconductor. Kev siv cov txaj granite yuav txuas ntxiv ua ib qho tseem ceeb rau ntau xyoo tom ntej, vim tias cov chaw tsim khoom siv zog los tsim cov khoom siv semiconductor zoo dua.
