Njengoko sonke sisazi, inkcazo ye-semiconductor kukuba inomoya oqhuba phakathi kwee-conductors ezomileyo kunye nee-insulators, umbane ohlala uphakathi kwesinyithi kunye ne-insulator, oqhele ukuba kubushushu begumbi ungaphakathi koluhlu lwe-1mΩ-cm ~ 1GΩ-cm. Kwiminyaka yakutshanje, i-vacuum semiconductor coating kwiinkampani ezinkulu ze-semiconductor, kuyacaca ukuba imeko yayo iphezulu ngakumbi, ingakumbi kwezinye iindlela ezinkulu zophando lwetekhnoloji yophuhliso lwesekethe yenkqubo edibeneyo kwiindlela zokuguqula izixhobo ze-magnetoelectric, izixhobo ezikhupha ukukhanya kunye neminye imisebenzi yophuhliso. I-vacuum semiconductor coating inendima ebalulekileyo.
Ii-semiconductors zibonakaliswa ziimpawu zazo zangaphakathi, ubushushu kunye noxinzelelo lokungcola. Izixhobo zokugquma ze-vacuum semiconductor zahlulwe enye kwenye ngokukodwa ziikhompawundi zayo. Phantse zonke zisekelwe kwi-boron, ikhabhoni, i-silicon, i-germanium, i-arsenic, i-antimony, i-tellurium, i-iodine, njl., kwaye ezinye zimbalwa kakhulu i-GaP, i-GaAs, i-lnSb, njl. njl. Kukwakho nezinye ii-semiconductors ze-oxide, ezifana ne-FeO, i-Fe₂O₃, i-MnO, i-Cr₂O₃, i-Cu₂O, njl.
Ukufuma kwe-vacuum, ukugquma okutshizayo, ukugquma kwee-ion kunye nezinye izixhobo kunokwenza ukugquma kwe-vacuum semiconductor. Ezi zixhobo zokugquma zahlukile kumgaqo wazo wokusebenza, kodwa zonke zenza izinto zokugquma ze-semiconductor ezibekwe kwi-substrate, kwaye njengezinto ezikwi-substrate, akukho mfuneko, ingaba yi-semiconductor okanye hayi. Ukongeza, ukugquma okuneempawu ezahlukeneyo zombane kunye ne-optical kunokulungiswa ngokusasazeka kokungcola kunye nokufakelwa kwee-ion kumphezulu we-substrate ye-semiconductor kuluhlu. Umaleko omncinci ophumayo unokucutshungulwa njenge-semiconductor coating ngokubanzi.
I-vacuum semiconductor coating yinto ebalulekileyo kwi-elektroniki nokuba yeyokusetyenziswa kwezixhobo ezisebenzayo okanye ezingasebenziyo. Ngenxa yokuqhubela phambili okuqhubekayo kwetekhnoloji ye-vacuum semiconductor coating, ulawulo oluchanekileyo lokusebenza kwefilimu luye lwaba nokwenzeka.
Kwiminyaka yakutshanje, i-amorphous coating kunye ne-polycrystalline coating ziye zenza inkqubela phambili ngokukhawuleza ekuvelisweni kwezixhobo ze-photoconductive, iityhubhu ze-coated field-effect, kunye neeseli zelanga ezisebenzayo kakhulu. Ukongeza, ngenxa yophuhliso lwe-vacuum semiconductor coating kunye ne-thin film yee-sensors, nto leyo enciphisa kakhulu ubunzima bokukhetha izinto kwaye yenza inkqubo yokuvelisa ibe lula kancinci. Izixhobo ze-vacuum semiconductor coating ziye zaba yinto ebalulekileyo kwizicelo ze-semiconductor. Ezi zixhobo zisetyenziswa kakhulu kwi-semiconductor coating yezixhobo zekhamera, ii-solar cells, ii-transistors ezifakwe i-coating, i-field emission, i-cathode-light, i-electron emission, izinto ezibonisa ifilimu encinci, njl.
Umgca wokugquma i-magnetron sputtering uyilwe ngenkqubo yolawulo oluzenzekelayo ngokupheleleyo, ujongano olulula noluqondakalayo lwesikrini sokuchukumisa somntu nomatshini. Umgca uyilwe ngemenyu yokusebenza epheleleyo ukufezekisa ukujonga ngokupheleleyo imeko yokusebenza kuzo zonke iindawo zomgca wemveliso, ukuseta iiparameter zenkqubo, ukhuseleko lokusebenza kunye nemisebenzi ye-alamu. Inkqubo yolawulo lombane iyonke ikhuselekile, ithembekile kwaye izinzile. Ixhotyiswe ngethagethi yokugquma i-magnetron enamacala amabini aphezulu nasezantsi okanye inkqubo yokugquma enamacala omabini.
Ezi zixhobo zisetyenziswa kakhulu kwiibhodi zesekethe ze-ceramic, ii-chip high-voltage capacitors kunye nezinye izinto ezisetyenziswa kakhulu ziibhodi zesekethe ze-elektroniki.
