Njengoko sonke siyazi, inkcazo ye-semiconductor kukuba ine-conductivity phakathi kwee-conductor ezomileyo kunye ne-insulators, i-resistantivity phakathi kwetsimbi kunye ne-insulator, ngokuqhelekileyo kwiqondo lokushisa eliqhelekileyo liphakathi kwe-1mΩ-cm ~ 1GΩ-cm. Kwiminyaka yakutshanje, vacuum semiconductor ukutyabeka kwiinkampani ezinkulu semiconductor, kucacile ukuba imeko yayo iya isanda phezulu, ingakumbi kwezinye ezinkulu-isikali edibeneyo inkqubo yophuhliso lwesekethe yophuhliso iindlela zophando uguqulo izixhobo magnetoelectric, izixhobo ukukhanya-emitting kunye neminye imisebenzi yophuhliso.Ukufakwa kwe-vacuum semiconductor kunendima ebalulekileyo.
I-semiconductors ibonakaliswe ngeempawu zabo zangaphakathi, ubushushu kunye nokuxinana kokungcola.Izinto zokugquma i-vacuum semiconductor zokwahlulwa omnye komnye ngokuyimbumba yazo.Phantse zonke zisekwe kwi-boron, i-carbon, isilicon, igermanium, i-arsenic, i-antimony, i-tellurium, i-iodine, njl., kunye ne-GaP, i-GaAs, i-lnSb embalwa, njl. MnO, Cr₂O₃, Cu₂O, njl.
Ukufunxa umphunga, ukugquma kwe-sputtering, ukugquma kwe-ion kunye nezinye izixhobo zinokwenza i-vacuum semiconductor yokwambathisa.Ezi zixhobo zokugubungela zonke zihluke kumgaqo wabo wokusebenza, kodwa zonke zenza i-semiconductor yezinto eziphathekayo ezifakwe kwi-substrate, kwaye njengezinto ze-substrate, akukho mfuneko, ingaba yi-semiconductor okanye cha.Ukongezelela, iingubo ezineepropati ezahlukeneyo zombane kunye ne-optical zingalungiswa ngokusasazwa kokungcola kunye nokufakelwa kwe-ion kumphezulu we-semiconductor substrate kuluhlu.Umaleko obhityileyo obangelwayo unokucutshungulwa njengengubo ye-semiconductor ngokubanzi.
Ivacuum semiconductor yokwambathisa bubukho obuyimfuneko kwizinto zombane nokuba zenzelwe izixhobo ezisebenzayo okanye ezingenzi nto.Ngokuqhubela phambili okuqhubekayo kwetekhnoloji ye-vacuum semiconductor yokwambathisa, ulawulo oluchanekileyo lokusebenza kwefilimu luye lwenzeka.
Kwiminyaka yakutshanje, i-amorphous coating kunye ne-polycrystalline coating yenze inkqubela phambili ngokukhawuleza ekwenzeni izixhobo ze-photoconductive, ii-tubes ze-effect field coated, kunye neeseli zelanga eziphezulu.Ukongeza, ngenxa yokuphuhliswa kwe-vacuum semiconductor coating kunye nefilimu encinci ye-sensors, ekwanciphisa kakhulu ubunzima bokukhethwa kwezinto kwaye yenza inkqubo yokuvelisa yenziwe lula.Izixhobo zokugquma i-vacuum semiconductor ziye zaba bubukho obuyimfuneko kwizicelo ze-semiconductor.Isixhobo sisetyenziswa ngokubanzi ukugquma kwe-semiconductor yezixhobo zekhamera, iiseli zelanga, ii-transistors ezigqunyiweyo, ukukhutshwa kwentsimi, ukukhanya kwe-cathode, ukukhutshwa kwe-electron, izinto ezincinci zokuva ifilimu, njl.
Umgca we-magnetron sputtering coating uyilwe ngenkqubo yokulawula ngokuzenzekelayo, i-interface elula kunye ne-intuitive touch screen yomntu-umatshini.Umgca wenzelwe imenyu epheleleyo yomsebenzi ukufezekisa ukubeka iliso ngokupheleleyo kwesimo sokusebenza kuwo wonke amacandelo omgca wokuvelisa, inkqubo yokumisela ipharamitha, ukukhuselwa komsebenzi kunye nemisebenzi ye-alamu.Yonke inkqubo yokulawula umbane ikhuselekile, ithembekile kwaye izinzile.Ixhotyiswe ngethagethi ye-sputtering yemagnetron ephezulu nangaphantsi emacaleni amabini okanye inkqubo yokwaleka enecala elinye.
Isixhobo sisetyenziswa kakhulu kwiibhodi zeesekethe ze-ceramic, i-chip high-voltage capacitors kunye nezinye iingubo ze-substrate, iindawo eziphambili zesicelo ziibhodi zeesekethe ze-elektroniki.
