Kev piav qhia
Silicon wafers yog cov khoom tseem ceeb hauv kev tsim cov khoom siv hluav taws xob, los ntawm microprocessors mus rau hnub ci hlwb. Thiab kev tsim cov silicon wafers cia siab rau ib qho tseem ceeb - silicon hlau hmoov.
Silicon hlau hmoov yog high-purity, finely av khoom ua los ntawm silicon hlau ingots. Nws muaj qhov sib txawv me me thiab cov duab, ua rau nws muaj qhov zoo tshaj plaws hauv kev tsim cov silicon wafers. Ua ntej peb delve rau hauv lub luag hauj lwm ntawm silicon hlau hmoov nyob rau hauv wafer ntau lawm, cia peb xub to taub dab tsi silicon wafers yog dab tsi thiab lawv yuav ua li cas.
Silicon wafers yog nyias puag ncig discs ua los ntawm silicon crystals uas ua raws li substrate rau hluav taws xob circuitry. Cov wafers yog tsim los ntawm cov txheej txheem Czochralski. Nyob rau hauv cov txheej txheem no, lub noob siv lead ua ntawm high-purity silicon yog dipped rau hauv molten silicon, uas maj mam txias thiab solidifies nyob ib ncig ntawm lub noob siv lead ua, tsim ib tug cylindrical silicon ingot. Tom qab ntawd lub ingot yog txiav mus rau hauv nyias slices, hu ua wafers, siv lub pob zeb diamond saw.

Silicon hlau hmoov ua lub luag haujlwm tseem ceeb hauv thawj kauj ruam ntawm cov txheej txheem Czochralski - kev npaj cov noob siv lead ua. Cov noob siv lead ua yuav tsum tau coated nrog ib txheej ntawm silicon nitride, uas ua raws li kev tiv thaiv kom tsis txhob molten silicon los ntawm lo rau cov siv lead ua. Silicon nitride yog tsim los ntawm reacting silicon hlau hmoov nrog ammonia roj ntawm qhov kub thiab txias. Lub resulting silicon nitride hmoov yog ces tov nrog ib tug neeg sawv cev, xws li ib tug resin, tsim ib tug slurry, uas yog siv rau cov noob siv lead ua nto thiab tso cai rau qhuav. Thaum qhuav, cov noob siv lead ua tau npaj siv rau hauv cov txheej txheem Czochralski.
Ntxiv rau ntawm kab, silicon hlau hmoov kuj tseem siv los npaj cov polycrystalline silicon rods siv nyob rau hauv txoj kev loj hlob ribbon rau hnub ci cell ntau lawm. Nyob rau hauv cov txheej txheem no, silicon hlau hmoov yog melted thiab tso cai rau solidify nyob rau hauv nyias ribbons. Tom qab ntawd cov ribbons raug txiav rau hauv me me thiab tsim rau hauv polycrystalline rods, uas yog siv los ua raw khoom rau hnub ci vaj huam sib luag.
Hauv kev xaus, silicon hlau hmoov yog ib qho tseem ceeb hauv kev tsim cov silicon wafers thiab solar panels. Nws yog siv rau hauv kev npaj cov noob siv lead ua rau cov txheej txheem Czochralski thiab polycrystalline silicon rods rau txoj kev loj hlob ribbon. Nws cov khoom tshwj xeeb, suav nrog kev ua siab dawb huv thiab tsis sib xws ntawm qhov loj me thiab cov duab, ua rau nws yog ib qho khoom siv tseem ceeb hauv kev tsim cov khoom siv hluav taws xob thiab cov thev naus laus zis tshiab.
