Sib tsoo log hauv Silicon Wafer Production

Kev sib tsoo plays lub luag haujlwm tseem ceeb hauv kev tsim cov silicon wafers. Kev ua lag luam nrhiav kom tau txais txiaj ntsig zoo dua, tus nqi zoo silicon wafers ua rau muaj teeb meem loj rau kev sib tsoo lub log ua haujlwm hauv kev lag luam no. Cov log no yuav tsum ua tau raws li cov qauv nruj, xws li kev puas tsuaj me me, kev hnav khaub ncaws tus kheej, kev ua haujlwm zoo, kev ua neej ntev, thiab kev them taus. Daim ntawv no muab cov ntaub ntawv qhia ntxaws ntxaws tsom rau kev sib tsoo lub log siv hauv kev tsim khoom siv silicon wafer. Nws tshawb txog kev nce qib tsis ntev los no hauv kev sib tsoo, kev sib txuas cov neeg ua haujlwm, kev tsim cov porosity, thiab cov qauv geometric ntawm kev sib tsoo log kom ua tiav cov kev xav tau no.

Silicon-based semiconductors yog ib qho tseem ceeb rau ntau yam kev siv, suav nrog cov tshuab computer, kev sib txuas lus, tsheb, khoom siv hluav taws xob, kev lag luam automation thiab tswj cov tshuab, thiab kev tiv thaiv technologies.

Txoj kev mus rau kev tsim cov qib siab tshaj plaws silicon wafers pib nrog kev loj hlob ntawm silicon ingots, uas tom qab ntawd dhau los ua cov txheej txheem los ua wafers. Cov kauj ruam yog raws li nram no:

Txiav- Txiav silicon ingots rau hauv nyias, disc-shaped wafers;

Flattening (Lapping lossis sib tsoo)- Txhim kho qhov flatness ntawm wafers;

Etching-Chemically tshem tawm kev puas tsuaj los ntawm slicing thiab flattening;

Polishing- Ua tiav qhov chaw du ntawm cov wafers;

Ntxuav- Tshem tawm cov tshuaj polishing lossis plua plav tawm ntawm qhov chaw wafer.

Kev sib tsoo ua haujlwm tsis yog tsuas yog ib txoj hauv kev rau kev sib tsoo hlau-sawn wafers tab sis kuj yog cov txheej txheem rau kev sib tsoo zoo etched wafers. Lub hom phiaj ntawm kev sib tsoo zoo etched wafers yog txhawm rau txhim kho qhov tiaj tus ntawm cov wafers ua ntej lawv nkag mus rau theem polishing, txo cov khoom tshem tawm thaum polishing. Qhov no ua rau muaj kev ua tau zoo hauv cov txheej txheem polishing thiab txhim kho flatness nyob rau hauv qhov kawg polished wafers.

Sib tsoo tseem pom daim ntawv thov hauv cov txheej txheem ua tiav cov khoom siv wafers ua ntej dicing lawv mus rau hauv ib tus neeg cov chips. Kev lag luam loj hlob rau nyias thiab hloov tau yooj yim silicon chips, xws li cov siv hauv cov ntawv ntse thiab RFID cov ntawv ntse, hu rau cov txheej txheem rov qab sib tsoo ntau dua.
