Hauv kev tsim khoom siab heev, cov tuam txhab Fortune 500 muaj cov kev cai nruj heev rau kev xaiv cov neeg muag khoom. Kev xaiv ntawm txhua yam khoom muaj feem cuam tshuam nrog cov khoom zoo thiab lub koob npe nrov ntawm lub tuam txhab. Nyob rau hauv xyoo tas los no, ntau tus neeg muag khoom Fortune 500 tau xaiv cov khoom siv granite ZHHIMG. Ib qho ntawm cov yam tseem ceeb tom qab qhov no yog tias nws tau ua tiav kev lag luam nrog cov coefficient thermal expansion ntawm 0.01μm / ° C.
Rau cov lag luam uas muaj kev ntsuas siab thiab kev lag luam zoo xws li kev tsim cov cuab yeej siv precision thiab kev ua cov khoom siv semiconductor, kev hloov pauv kub hauv qhov chaw tsim khoom yog qhov tsis zam. Cov khoom ua los ntawm cov khoom siv ib txwm muaj, vim lawv cov coefficient ntawm thermal expansion siab, yuav hloov pauv qhov ntev thaum qhov kub hloov pauv. Cov kev hloov pauv me me no tau nthuav dav tas li hauv kev ua haujlwm precision, ua rau kev poob qis ntawm qhov tseeb ntawm cov khoom siv thiab kev nce ntxiv ntawm cov khoom tsis zoo. Raws li kev tshawb fawb cuam tshuam, hauv qee cov txheej txheem tsim khoom semiconductor chip nrog cov kev xav tau siab heev, rau txhua qhov kev hloov pauv kub 1 ° C, kev nthuav dav thermal ntawm cov khoom siv hlau ib txwm muaj peev xwm ua rau qhov sib txawv ntawm lub voj voog chip dhau qhov ntau yam tso cai, nrog rau tus nqi pov tseg siab txog 20% txog 30%, cuam tshuam loj heev rau kev ua haujlwm zoo thiab cov txiaj ntsig kev lag luam ntawm cov tuam txhab.
Cov khoom siv granite ZHHIMG, nrog rau qhov coefficient thermal expansion qis heev ntawm 0.01μm/°C, tau tawg tag nrho los ntawm qhov teeb meem kev lag luam no. Cov granite ntuj tsim los ntawm cov txheej txheem geological ntev thaum nws tsim, ua rau muaj cov qauv ntom thiab sib xws. Raws li qhov no, ZHHIMG tau txhim kho kev ua tau zoo ntawm cov khoom granite los ntawm kev siv cov txheej txheem ua tiav thiab cov txheej txheem tswj xyuas zoo. Thaum qhov kub sab nraud hloov pauv, qhov loj ntawm cov khoom granite ZHHIMG tseem yuav luag tsis hloov pauv, muab kev txhawb nqa tas mus li thiab ruaj khov rau cov khoom siv. Piv txwv li, siv cov khoom siv tshuaj xyuas qhov muag pom tseeb. Tom qab siv cov khoom granite ZHHIMG, txawm tias thaum ua haujlwm tas li hauv ib puag ncig uas muaj qhov sib txawv ntawm qhov kub thiab txias loj ntawm hnub thiab hmo ntuj, qhov kev ntsuas qhov tseeb ntawm cov khoom siv tuaj yeem tswj tau hauv qhov ntau me me, ua kom ntseeg tau tias qhov tseeb thiab kev ntseeg tau ntawm cov txiaj ntsig tshuaj xyuas, thiab txhim kho qhov ua tau zoo thiab qhov tseeb ntawm kev tshuaj xyuas khoom zoo.
Ntxiv rau nws qhov kev ruaj khov thermal zoo heev, cov khoom siv granite ZHHIMG kuj muaj ntau yam zoo. Nws qhov hardness siab heev, ncav cuag 6-7 ntawm Mohs scale. Nws tuaj yeem tiv taus cov khoom siv kho tshuab siab, tsis yooj yim deformation lossis hnav, thiab yog li ntawd ntev lub neej kev pabcuam ntawm cov khoom siv. Lub caij no, lub zog nqus dej ntawm granite tuaj yeem nqus tau cov kev co uas tsim thaum lub sijhawm ua haujlwm ntawm cov khoom siv, txo qhov cuam tshuam ntawm kev co rau qhov ua tiav. Hauv cov khoom siv txiav semiconductor wafer, kev siv cov khoom siv granite ZHHIMG ua rau cov txheej txheem txiav ruaj khov dua, ua tiav qhov kev txiav raug siab dua, txo qhov nrawm ntawm wafer tawg, thiab txhim kho kev ua haujlwm ntau lawm.
Cov tuam txhab Fortune 500 muab qhov tseem ceeb rau kev sib raug zoo mus sij hawm ntev thiab ruaj khov. ZHHIMG tsis yog tsuas yog ua tau zoo hauv cov khoom zoo xwb tab sis kuj muaj cov kev pabcuam tiav. ZHHIMG tuaj yeem muab kev txhawb nqa rau cov neeg siv khoom txhua yam. Nws pab pawg kws tshaj lij tuaj yeem teb sai rau cov neeg siv khoom xav tau, daws ntau yam teeb meem uas cov neeg siv khoom ntsib thaum lub sijhawm siv, thiab tiv thaiv kev tsim khoom thiab kev ua haujlwm ntawm cov tuam txhab.
