Granite yog ib yam khoom siv uas siv ntau hauv ntau yam lag luam vim nws ruaj khov, muaj zog, thiab muaj peev xwm tiv taus kev hnav thiab tsim kua muag. Ib qho ntawm cov ntawv thov ntawm granite yog nyob rau hauv cov txheej txheem tsim khoom semiconductor uas nws siv ua lub hauv paus rau kev tsim cov microchips, integrated circuits, thiab lwm yam khoom siv hluav taws xob.
Ib qho ntawm cov khoom tseem ceeb ntawm kev tsim khoom semiconductor yog photolithography, uas cuam tshuam nrog kev siv lub teeb los hloov cov qauv mus rau ntawm silicon wafer. Cov phaj granite siv rau hauv cov txheej txheem no ua lub hauv paus uas cov zaj duab xis nyias siv los hloov cov qauv yog coated. Granite yog nyiam hauv photolithography vim nws qhov tiaj tiaj, uas ua kom ntseeg tau tias cov zaj duab xis nyias siv rau ntawm nws qhov chaw yog du thiab sib xws. Kev siv du thiab sib xws ntawm cov zaj duab xis nyias yog qhov tseem ceeb hauv kev ua kom ntseeg tau tias cov qauv tsim ntawm wafer yog qhov tseeb thiab meej.
Granite kuj tseem siv rau hauv kev tsim cov rooj ua haujlwm thiab cov khoom siv hauv chav huv. Thaum lub sijhawm tsim cov semiconductors, kev huv yog qhov tseem ceeb tshaj plaws, thiab txhua yam khoom me me lossis hmoov av tuaj yeem ua rau puas tsuaj rau cov khoom. Yog li ntawd, cov ntaub ntawv siv hauv chav huv yuav tsum tsis txhob poob, tsis muaj tshuaj lom, thiab yooj yim ntxuav. Granite ua tau raws li cov kev cai no, ua rau nws yog cov khoom siv zoo meej rau kev tsim cov rooj ua haujlwm thiab lwm yam khoom siv hauv chav huv.
Lwm qhov kev siv granite hauv kev tsim khoom semiconductor yog hauv kev tsim cov tshuab nqus tsev. Lub tshuab nqus tsev yog qhov tseem ceeb hauv cov txheej txheem tsim khoom vim nws siv los tsim ib puag ncig qis-siab uas ua kom ntseeg tau tias cov khoom semiconductor tsim tawm zoo. Lub zog siab thiab cov coefficient qis ntawm thermal expansion ntawm granite ua rau nws yog cov khoom siv txhim khu kev qha rau kev tsim cov chav nqus tsev.
Xaus lus, granite yog ib yam khoom muaj nqis hauv kev tsim khoom semiconductor vim nws cov khoom tshwj xeeb xws li kev ruaj khov, lub zog, thiab kev ruaj khov thermal. Qhov tiaj tiaj thiab kev huv ntawm granite ua rau nws haum rau photolithography, chav ua haujlwm huv, thiab lub tshuab nqus tsev. Kev siv granite hauv kev lag luam semiconductor yog ib qho pov thawj rau nws qhov kev hloov pauv thiab kev hloov pauv mus rau ntau yam kev siv, ua pov thawj tias nws tsis yog tsuas yog cov khoom siv kho kom zoo nkauj xwb tab sis kuj yog ib qho tseem ceeb hauv ntau yam txheej txheem kev lag luam.
