Taw qhia ntawm lub thawv wafer
Cov txheej txheem tseem ceeb ntawm kev tsim cov oxidized silicon wafers feem ntau suav nrog cov kauj ruam hauv qab no: kev loj hlob ntawm monocrystalline silicon, txiav rau hauv wafers, polishing, ntxuav thiab oxidation.
Kev loj hlob ntawm Monocrystalline silicon: Ua ntej, monocrystalline silicon raug loj hlob ntawm qhov kub siab los ntawm cov txheej txheem xws li Czochralski txoj kev lossis Float-zone txoj kev. Txoj kev no ua rau muaj peev xwm npaj cov silicon ib leeg siv lead ua ke nrog kev ntshiab siab thiab kev ncaj ncees ntawm lattice.
Kev Txiav: Cov monocrystalline silicon uas loj hlob feem ntau yog nyob rau hauv ib lub cylindrical zoo li thiab yuav tsum tau txiav rau hauv cov wafers nyias nyias kom siv tau ua lub wafer substrate. Kev txiav feem ntau yog ua nrog lub tshuab txiav pob zeb diamond.
Kev txhuam: Qhov saum npoo ntawm cov wafer txiav yuav tsis sib npaug thiab xav tau kev txhuam tshuaj lom neeg kom tau txais qhov chaw du.
Kev Ntxuav: Lub wafer polished yog ntxuav kom tshem tawm cov impurities thiab hmoov av.
Oxidizing: Thaum kawg, cov silicon wafers raug muab tso rau hauv lub cub tawg kub siab rau kev kho oxidizing los tsim ib txheej tiv thaiv ntawm silicon dioxide los txhim kho nws cov khoom hluav taws xob thiab lub zog kho tshuab, nrog rau ua haujlwm ua ib txheej insulating hauv cov voj voog sib xyaw.
Cov kev siv tseem ceeb ntawm cov oxidized silicon wafers suav nrog kev tsim cov integrated circuits, kev tsim cov hnub ci cell, thiab kev tsim lwm yam khoom siv hluav taws xob. Silicon oxide wafers yog siv dav hauv cov ntaub ntawv semiconductor vim lawv cov khoom siv zoo heev, kev ruaj khov ntawm qhov ntev thiab tshuaj lom neeg, muaj peev xwm ua haujlwm ntawm qhov kub thiab txias siab, nrog rau cov khoom rwb thaiv tsev thiab kho qhov muag zoo.
Nws cov txiaj ntsig suav nrog cov qauv siv lead ua tiav, cov tshuaj lom neeg ntshiab, qhov ntev meej, cov khoom siv kho tshuab zoo, thiab lwm yam. Cov yam ntxwv no ua rau silicon oxide wafers tshwj xeeb tshaj yog rau kev tsim cov khoom siv sib xyaw ua ke thiab lwm yam khoom siv microelectronic.
