Taw qhia ntawm wafer box

Cov txheej txheem tseem ceeb ntawm kev tsim oxidized silicon wafers feem ntau suav nrog cov kauj ruam hauv qab no: monocrystalline silicon kev loj hlob, txiav rau hauv wafers, polishing, tu thiab oxidation.

Monocrystalline silicon kev loj hlob: Ua ntej, monocrystalline silicon yog loj hlob ntawm qhov kub thiab txias los ntawm txoj kev xws li Czochralski txoj kev los yog Float-zone method. Txoj kev no ua rau kev npaj ntawm silicon ib leeg muaju nrog siab purity thiab lattice kev ncaj ncees.

Dicing: Cov qoob loo monocrystalline silicon feem ntau yog nyob rau hauv cov duab cylindrical thiab yuav tsum tau txiav rau hauv nyias wafers siv los ua wafer substrate. Txiav feem ntau yog ua nrog lub pob zeb diamond cutter.

Polishing: Qhov saum npoo ntawm qhov txiav wafer yuav tsis sib npaug thiab yuav tsum tau siv tshuaj-mechanical polishing kom tau qhov chaw du.

Ntxuav: Lub polished wafer yog ntxuav kom tshem tawm impurities thiab hmoov av.

Oxidizing: Thaum kawg, silicon wafers tau muab tso rau hauv lub qhov cub kub kub rau oxidizing kev kho mob los tsim ib txheej tiv thaiv ntawm silicon dioxide los txhim kho nws cov khoom hluav taws xob thiab lub zog txhua yam, nrog rau kev ua cov txheej txheem insulating hauv kev sib xyaw ua ke.

Cov kev siv tseem ceeb ntawm oxidized silicon wafers suav nrog kev tsim khoom ntawm kev sib xyaw ua ke, kev tsim cov hnub ci hlwb, thiab kev tsim khoom ntawm lwm yam khoom siv hluav taws xob. Silicon oxide wafers tau siv dav hauv kev lag luam ntawm cov khoom siv semiconductor vim lawv cov khoom siv zoo heev, qhov ntev thiab tshuaj lom neeg ruaj khov, muaj peev xwm ua haujlwm ntawm qhov kub thiab txias siab, nrog rau zoo insulating thiab optical zog.

Nws qhov zoo muaj xws li cov qauv siv lead ua tiav, cov tshuaj dawb huv, qhov ntev, cov khoom siv zoo, thiab lwm yam. Cov yam ntxwv no ua rau silicon oxide wafers tshwj xeeb tshaj yog tsim rau kev tsim cov khoom siv hluav taws xob sib xyaw ua ke thiab lwm yam khoom siv microelectronic.
