Kev ua wafer tau dhau los ua ib feem tseem ceeb ntawm ntau yam kev lag luam, suav nrog hluav taws xob, semiconductors, thiab hnub ci zog.Cov txheej txheem cuam tshuam nrog polishing, etching, thiab tu qhov chaw ntawm lub wafer los npaj nws rau kev ua haujlwm.Wafer ua khoom siv yog cov tshuab siv hauv cov txheej txheem no.
Ib qho tseem ceeb ntawm cov khoom siv ua wafer yog cov khoom siv granite.Granite yog cov khoom nyiam rau kev tsim cov khoom no vim nws cov kav ntev, ruaj khov, thiab tsis muaj qhov ntxeem tau.Granite Cheebtsam yog siv rau hauv cov khoom siv xws li lapping tshuab, polishing tshuab, thiab wafer tshuaj xyuas tshuab.
Ntawm no yog yuav ua li cas siv wafer ua khoom siv granite Cheebtsam:
1. Kev ntxuav
Ua ntej siv cov khoom siv granite, lawv yuav tsum tau ntxuav kom huv si.Granite yog cov khoom siv tsis muaj qhov ntxeem tau, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau wafer ua khoom siv.Txawm li cas los xij, nws tseem tuaj yeem sau cov av thiab cov kab mob sib kis uas tuaj yeem cuam tshuam rau cov txheej txheem wafer.
Siv cov dej huv thiab cov ntaub mos muag, so cov av, roj, lossis cov khib nyiab los ntawm cov khoom siv granite.Koj tuaj yeem siv cov tshuaj xab npum me me rau cov tawv nqaij tawv.
2. Kev sib dhos
Qee cov khoom siv yuav tsum tau siv ntau yam khoom siv granite rau cov txheej txheem wafer.Piv txwv li, lub tshuab lapping muaj ntau yam granite, suav nrog cov txee, rooj ua haujlwm, thiab lub taub hau lapping.
Thaum sib sau cov khoom siv granite, xyuas kom txhua qhov chaw huv si thiab tsis muaj cov khib nyiab kom tsis txhob muaj kab mob ntawm cov wafers.
3. Kev tu
Granite Cheebtsam yuav tsum tau saib xyuas tsawg heev vim lawv tiv taus hnav thiab tsim kua muag.Txawm li cas los xij, nws yog ib qho kev xyaum zoo los tshuaj xyuas cov khoom tsis tu ncua kom ntseeg tau tias lawv ua haujlwm raug.
Tshawb xyuas cov kab nrib pleb, chips, lossis khawb hauv granite nto, vim tias lawv tuaj yeem cuam tshuam cov txheej txheem wafer.Cov kev puas tsuaj zoo li no tuaj yeem kho nrog epoxy, tab sis nws raug nquahu kom hloov cov khoom siv yog tias qhov kev puas tsuaj loj heev.
4. Calibration
Yuav kom ua tiav qhov siab precision hauv kev ua wafer, cov cuab yeej yuav tsum muaj cov khoom siv granite kom zoo.Calibration xyuas kom meej tias lub tshuab txav kom raug thiab tsis tu ncua mus rau txoj haujlwm xav tau.
Qhov no yog ua tiav los ntawm aligning cov granite Cheebtsam ntawm cov cuab yeej rau cov specifications yuav tsum tau.Nws yog ib qho tseem ceeb uas yuav tsum tsis txhob saib xyuas, vim tias qhov tsis raug calibration tuaj yeem ua rau wafer puas lossis ua tsis zoo.
Xaus
Wafer ua cov cuab yeej yog qhov tseem ceeb rau ntau yam kev lag luam, thiab cov khoom siv granite ua lub luag haujlwm tseem ceeb hauv cov txheej txheem.Kev siv kom raug thiab kev saib xyuas ntawm cov khoom no lav kev ua haujlwm zoo thiab kev pabcuam siab tshaj plaws.
Los ntawm ua raws li cov kauj ruam saum toj no, koj tuaj yeem xyuas kom meej tias koj siv koj cov khoom siv granite kom raug, kom ntseeg tau tias koj cov khoom siv wafer ua tau zoo rau lub sijhawm ntev.
