Mitundu ya Zida Zophikira Vacuum

Ukadaulo wopaka utoto wa vacuum umadziwika kwambiri chifukwa cha kusamala chilengedwe, kugwira ntchito bwino kwambiri, kufanana kwabwino kwa filimu, komanso kuchuluka kwa mafilimu. Mu ntchito zamafakitale, zida zopaka utoto wa vacuum nthawi zambiri zimagawidwa m'magulu awiri akuluakulu: Kuyika Utsi Wathupi (PVD) ndi Kuyika Utsi Wamankhwala (CVD).

Machitidwe a Physical Nthunzi Yotulutsa Mpweya (PVD) akuphatikizapo evaporation, sputtering, ndi ion plating technologies. Machitidwe a evaporation plating amagwiritsa ntchito njira zosiyanasiyana zotenthetsera kuti atenthetse zinthu zophimba, monga resistance heating evaporation, electron beam evaporation (E-beam), induction heating evaporation, ndi arc evaporation. Koma machitidwe a sputtering sputtering, amadalira plasma-induced target atomic ejection ndipo amaphatikizapo direct current (DC) sputtering, radio frequency (RF), magnetron sputtering, ndi reactive sputtering processes. Machitidwe a ion plating amaphatikiza plasma ndi evaporation kapena sputtering mechanisms kuti awonjezere kumatirira ndi kuchulukana kwa filimu, ndi ukadaulo wamba kuphatikizapo cathodic arc ion plating, magnetron sputtering ion plating, ndi hollow cathode ion plating.

Machitidwe a Chemical Nthunzi Yotulutsa Mpweya (CVD) amagwiritsa ntchito mankhwala omwe amapangidwa ndi zinthu zoyambira mpweya kuti apange mafilimu olimba pa malo oyambira. Maukadaulo odziwika bwino a CVD ndi monga Atmospheric Pressure Chemical Nthunzi Yotulutsa Mpweya (APCVD), Low Pressure Chemical Nthunzi Yotulutsa Mpweya (LPCVD), Plasma Enhanced Chemical Nthunzi Yotulutsa Mpweya (PECVD), Metal-Organic Chemical Nthunzi Yotulutsa Mpweya (MOCVD), ndi Atomic Layer Deposition (ALD), iliyonse imagwirizana ndi machitidwe osiyanasiyana azinthu ndi zofunikira pa ntchito.

Ukadaulo wopaka utoto wa vacuum umagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo kupanga magalimoto, zamagetsi ndi zamagetsi (monga mafoni a m'manja), ma semiconductors, zida zapakhomo, zida zaukhondo, zinthu zamafuta za tsiku ndi tsiku, zinthu zokongoletsera, ndi zipangizo zosinthasintha zamafilimu.
