Cov kev faib tawm ntawm cov khoom siv nqus tsev yog dab tsi?

Cov txheej txheem nqus tsev yog ib txoj kev siv tshuab uas tso cov khoom siv zaj duab xis nyias rau ntawm qhov chaw ntawm cov khoom siv substrate hauv qab qhov chaw nqus tsev, uas yog siv dav hauv cov khoom siv hluav taws xob, optics, ntim khoom, kho kom zoo nkauj thiab lwm yam. Cov khoom siv nqus tsev feem ntau muab faib ua cov hom hauv qab no:

1. Cov khoom siv thermal evaporation coating: qhov no yog txoj kev nqus tsev txheej txheem ib txwm muaj, los ntawm kev ua kom cov khoom siv zaj duab xis nyias nyias hauv lub nkoj evaporation, cov khoom siv tau evaporated thiab tso rau ntawm qhov chaw ntawm cov khoom siv substrate.
2. Cov khoom siv txheej sputtering: siv cov ions muaj zog siab los ntaus rau ntawm qhov chaw ntawm cov khoom siv, cov khoom siv atoms raug sputtered thiab tso rau hauv cov khoom siv substrate. Magnetron sputtering muaj peev xwm tau txais cov nplaum zoo dua thiab muaj zog dua ntawm cov yeeb yaj kiab, tsim nyog rau kev tsim khoom loj.
3. Cov khoom siv tso cov kab hluav taws xob ion: Cov kab hluav taws xob ion yog siv los tso cov ntaub ntawv zaj duab xis nyias rau ntawm lub substrate. Txoj kev no tuaj yeem tau txais cov zaj duab xis sib xws heev thiab tsim nyog rau cov xwm txheej nrog cov kev xav tau siab, tab sis tus nqi khoom siv siab.
4. Cov Khoom Siv Tshuaj Lom Zem (CVD): Tsim cov zaj duab xis nyias nyias rau ntawm qhov chaw ntawm cov khoom siv substrate los ntawm kev tshuaj lom neeg. Txoj kev no tuaj yeem npaj cov zaj duab xis zoo, ntau hom, tab sis cov khoom siv nyuaj thiab kim heev.
5. Cov khoom siv Molecular Beam Epitaxy (MBE): Qhov no yog ib txoj kev los tswj kev loj hlob ntawm cov zaj duab xis nyias nyias ntawm qib atomic thiab feem ntau yog siv rau kev npaj cov txheej nyias nyias thiab cov qauv ntau txheej rau cov ntawv thov semiconductor thiab nanotechnology.
6. Cov khoom siv Plasma Enhanced Chemical Vapour Deposition (PECVD): Qhov no yog ib txoj kev siv plasma los txhim kho kev tso cov zaj duab xis nyias los ntawm kev tshuaj lom neeg, ua rau muaj kev tsim cov zaj duab xis nyias sai sai ntawm qhov kub qis dua.
7. Cov khoom siv Pulsed Laser Deposition (PLD): Cov no siv cov laser pulses siab zog los ntaus lub hom phiaj, ua kom cov khoom tawm ntawm qhov chaw ntawm lub hom phiaj thiab tso nws rau ntawm ib lub substrate, thiab tsim nyog rau kev cog cov yeeb yaj kiab oxide zoo, nyuaj.
Txhua yam ntawm cov khoom siv no muaj nws tus kheej cov yam ntxwv hauv kev tsim thiab kev ua haujlwm thiab tsim nyog rau ntau yam kev siv hauv kev lag luam thiab thaj chaw tshawb fawb. Nrog rau kev txhim kho ntawm thev naus laus zis, kev siv tshuab nqus tsev kuj tau nce qib, thiab cov khoom siv nqus tsev tshiab kuj tau tshwm sim.
