PVD (Physical Vapor Deposition) txheej tshuab nqus tsev yog ib qho txheej txheem uas siv lub tshuab nqus tsev los tso cov zaj duab xis nyias nyias ntawm cov khoom rau ntawm ib lub substrate. Cov thev naus laus zis no tau siv dav hauv kev tsim khoom los txhim kho kev ua tau zoo thiab qhov zoo nkauj ntawm ntau yam khoom, thiab tam sim no kuj tau siv rau kev tsim cov diav yas.
Lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab nqus tsev PVD txheej yas yog ua kom cov khoom khov xws li hlau ua pa hauv lub tshuab nqus tsev. Cov khoom ua pa ces sib sau ua ke rau ntawm qhov chaw ntawm lub diav yas, tsim cov txheej nyias nyias. Cov txheej txheem no tsis yog tsuas yog txhim kho qhov ruaj khov ntawm cov diav xwb, tab sis kuj ua rau lawv du thiab zoo nkauj.
Kev siv cov tshuab nqus tsev PVD txheej hauv kev tsim cov diav yas yog qhov txaus siab rau ntau yam. Ua ntej, nws tso cai rau cov chaw tsim khoom tsim ntau cov diav uas tiv taus kev hnav, ua rau lawv haum rau ntau yam kev siv. Tsis tas li ntawd, cov txheej txheem no tuaj yeem siv los siv ntau yam kho kom zoo nkauj rau cov diav kom ua rau lawv zoo li kim dua.
Tsis ntev los no tau tshaj tawm tias ib lub tuam txhab ua khoom siv ua diav yas tau tshaj tawm tias lawv tau teeb tsa lub tshuab nqus tsev PVD uas zoo tshaj plaws hauv nws lub chaw tsim khoom. Qhov kev nqis peev tseem ceeb no qhia txog lawv txoj kev cog lus los muab cov khoom lag luam zoo thiab tshiab rau lawv cov neeg siv khoom. Lub tuam txhab xav tias kev siv cov thev naus laus zis no yuav tsis tsuas yog txhim kho kev ua tau zoo ntawm cov diav yas xwb tab sis kuj qhib lub qhov rooj rau cov cib fim tshiab hauv kev lag luam.
Qhov kev tso tawm ntawm lub tshuab nqus tsev PVD rau cov diav yas yog ib qho kev hloov pauv mus rau kev tsim khoom ruaj khov dua. Los ntawm kev txhim kho qhov ruaj khov thiab kev zoo nkauj ntawm cov diav yas, cov thev naus laus zis no tuaj yeem pab txo qhov kev siv tag nrho thiab kev pov tseg ntawm cov khoom siv yas siv ib zaug xwb. Tsis tas li ntawd, lub peev xwm los siv cov khoom dai kom zoo nkauj tuaj yeem ua rau cov diav yas tsim nyog dua rau kev siv dua, yog li pab txhawb rau txoj kev noj mov ruaj khov dua thiab zoo rau ib puag ncig.
Raws li qhov kev thov rau cov diav yas zoo txuas ntxiv mus, kev siv cov tshuab nqus tsev PVD yuav tsum tau nthuav dav thoob plaws hauv kev lag luam. Cov chaw tsim khoom lees paub qhov tseem ceeb ntawm kev nqis peev rau cov thev naus laus zis siab heev kom nyob ua ntej ntawm cov neeg sib tw thiab ua tau raws li qhov xav tau ntawm cov neeg siv khoom.
