Wafer kev tawm tsam tau dhau los ua kev sib raug zoo ntawm ntau yam kev lag luam, suav nrog cov khoom siv hluav taws xob, suav nrog, soniconductors, thiab hnub ci zog. Cov txheej txheem cuam tshuam nrog polishing, etching, thiab ntxuav lub nplaim ntawm wafer los npaj nws rau kev ua. Cov khoom siv muaj kev nyab xeeb yog cov tshuab siv hauv cov txheej txheem no.
Ib qho kev tiv thaiv kev nyab xeeb ntawm cov khoom siv ua si yog cov khoom siv granite. Granite yog cov khoom uas nyiam tshaj rau kev tsim cov khoom lag luam no vim nws qhov kev ua haujlwm durability, thiab tsis muaj tseeb. Granite yog siv nyob rau hauv cov khoom siv xws li lapping machine, Polishing machine, thiab kev tshuaj ntsuam cov tshuab tawm.
Ntawm no yog yuav ua li cas siv Wafefer Ua Khoom Siv Granite:
1. Ntxuav
Ua ntej siv cov khoom siv granite, lawv yuav tsum tau ntxuav kom huv si. Granite yog cov khoom uas tsis muaj-ntxeem tau, ua rau kev xaiv zoo tshaj plaws rau kev tiv thaiv cov khoom siv. Txawm li cas los xij, nws tseem tuaj yeem nthuav cov av thiab cov paug uas yuav cuam tshuam nrog kev ua haujlwm wafer.
Siv dej huv thiab daim ntaub mos muag, muab dej muag muag, roj, lossis khib nyiab los yog khib nyiab los ntawm cov npoo av ntawm granite. Koj tseem tuaj yeem siv xab npum tov tshuaj me rau cov nyhav heev.
2. Sib Dhos
Qee cov cuab yeej siv yuav tsum siv ntau yam khoom siv granite rau kev ua haujlwm ntawm kev ua haujlwm. Piv txwv li, lub tshuab lapping muaj ntau yam khoom, suav nrog cov countertop, rooj ua haujlwm, thiab lub taub hau lapping.
Thaum sib xyaw ua ke cov cheebtsam loj, ua kom txhua qhov chaw yog huv si thiab tsis muaj cov khib nyiab kom txhob ua paug rau cov khoom siv wafers.
3. Txij Nkawm
Cov cheebtsam Granite xav tau kev txij nkawm tsawg heev vim tias lawv tiv taus kev hnav thiab kua muag. Txawm li cas los xij, nws yog qhov kev coj ua zoo los tshawb xyuas cov khoom siv tsis tu ncua kom ntseeg tau tias lawv ua haujlwm kom raug.
Txheeb xyuas cov kab nrib pleb, daim tawv nyias, lossis khawb hauv cov npoo granite, raws li lawv tuaj yeem cuam tshuam rau kev ua haujlwm wafer. Xws li kev puas tsuaj tuaj yeem kho nrog epoxy, tab sis nws raug nquahu kom hloov cov khoom sib xyaw yog tias kev puas tsuaj ntau.
4. Calibration
Txhawm rau kom ua tiav qhov kev ua kom muaj kev tiv thaiv zoo nyob hauv kev ua haujlwm wafer, cov cuab yeej yuav tsum muaj cov khoom sib dhos kom zoo. Kev ntsuas hluav taws kom ua kom pom tseeb tias cov tshuab txav kom yog thiab xwm yeem rau txoj haujlwm xav tau.
Qhov no yog tiav los ntawm kev sib dhos cov tshuab granite ntawm cov khoom siv rau cov lus qhia tshwj xeeb. Nws yog cov kauj ruam tseem ceeb uas yuav tsum tsis txhob dhau mus, raws li kev ntsuas hluav taws xob tsis muaj peev xwm ua rau muaj kev puas tsuaj lossis cov txiaj ntsig ua haujlwm.
Tag
Wafer ua khoom siv yog qhov tseem ceeb rau ntau yam kev lag luam, thiab cov cheebtsam granite ua lub luag haujlwm tseem ceeb hauv cov txheej txheem. Kev siv kev siv thiab kho kom raug ntawm cov khoom siv tau lees paub tau zoo tshaj plaws thiab lub neej pabcuam tshaj plaws.
Los ntawm kev ua raws li cov kauj ruam saum toj no, koj tuaj yeem siv koj cov khoom siv granite kom raug, kom koj cov khoom siv ua tau zoo rau lub sijhawm ncua.
