Silicon crystal process filtration yog hais txog kev siv cov tshuab pom hauv cov txheej txheem silicon siv lead ua kom tshem tawm cov impurities thiab impurity hais, yog li txhim kho cov purity thiab zoo ntawm silicon crystals. Cov txheej txheem filtration feem ntau siv hauv cov txheej txheem silicon crystal muaj xws li hauv qab no:
1.Vacuum Filtration:Muab cov pob zeb silicon tso rau hauv lub tshuab nqus tsev thiab siv lub tshuab nqus tsev los lim tawm cov impurities los ntawm cov kua. Txoj kev no tuaj yeem tshem tawm feem ntau impurities thiab hais, tab sis tsis tuaj yeem tshem tawm cov khoom me me.
2. Mechanical Filtration:Los ntawm immersing silicon crystals rau hauv lim xov xwm, xws li cov ntawv lim, lim tshuaj, thiab lwm yam., impurities thiab hais yog lim los ntawm kev siv lub micropore loj ntawm cov lim xov xwm. Txoj kev no yog tsim rau lim impurities ntawm loj hais.
3. Centrifugal Lim:Los ntawm kev tig lub centrifuge, impurities thiab hais nyob rau hauv cov kua yog precipitated mus rau hauv qab ntawm lub centrifuge raj siv centrifugal quab yuam, yog li ua tiav pom. Txoj kev no tsim nyog rau kev tshem tawm cov khoom me me thiab cov khoom hauv kev ncua.
4. Siab lim:Siv lub siab kom dhau cov kua los ntawm qhov nruab nrab lim dej, yog li lim tawm impurities thiab hais. Txoj kev no tuaj yeem lim cov kua dej ntau sai thiab muaj qee qhov kev txwv ntawm qhov loj me.
Qhov tseem ceeb ntawm silicon siv lead ua filtration yog nyob rau hauv kev txhim kho cov purity thiab zoo ntawm silicon crystals, uas yog ib qho tseem ceeb rau kev tsim khoom zoo semiconductor li. Los ntawm kev lim dej kom zoo, cov ntsiab lus impurity hauv silicon muaju tuaj yeem txo qis, qhov tsis xws luag tuaj yeem txo, qhov sib xws ntawm kev loj hlob siv lead ua thiab kev ncaj ncees ntawm cov qauv siv lead ua tuaj yeem txhim kho, yog li txhim kho kev ua haujlwm thiab kev ntseeg siab ntawm cov khoom siv semiconductor.
Silicon crystal yog hais txog cov khoom siv uas nws cov qauv siv lead ua yog tsim los ntawm silicon atoms thiab yog ib qho tseem ceeb ntawm cov khoom siv semiconductor. Silicon crystals muaj cov khoom siv hluav taws xob zoo thiab thermal thiab tau siv dav hauv cov khoom siv optoelectronic, cov khoom siv semiconductor, hnub ci vaj huam sib luag, kev sib koom ua ke thiab lwm yam khoom.
