Njengoba sonke sazi, incazelo ye-semiconductor iwukuthi ine-conductivity phakathi kwama-conductor owomile kanye nama-insulators, ukumelana nokumelana phakathi kwensimbi ne-insulator, okuvame ukushisa ekamelweni kungaphakathi kwebanga le-1mΩ-cm ~ 1GΩ-cm.Eminyakeni yamuva nje, i-vacuum semiconductor enamathela ezinkampanini ezinkulu ze-semiconductor, kuyacaca ukuthi isimo saso siya ngokuya siphezulu, ikakhulukazi kwezinye izindlela zokucwaninga zokuthuthukiswa kobuchwepheshe besifunda esikhulu esididiyelwe kumadivayisi okuguqulwa kwe-magnetoelectric, amadivaysi akhipha ukukhanya kanye neminye imisebenzi yokuthuthukiswa.Ukufakwa kwe-vacuum semiconductor kunendima ebalulekile.
Ama-semiconductors abonakala ngezici zawo zangaphakathi, izinga lokushisa nokugxilisa ukungcola.Izinto zokumboza ze-vacuum semiconductor zihlukaniswa komunye nomunye ikakhulukazi ngezinhlanganisela zayo.Cishe zonke zisuselwe ku-boron, ikhabhoni, i-silicon, i-germanium, i-arsenic, i-antimony, i-tellurium, i-iodine, njll., kanye nama-GaP, ama-GaA, ama-lnSb ambalwa, njll. MnO, Cr₂O₃, Cu₂O, njll.
Ukuhwamuka kwe-vacuum, ukugcotshwa kwe-sputtering, ukunamathela kwe-ion nezinye izinto zokusebenza kungenza ukunamathela kwe-vacuum semiconductor.Lezi zixhobo zokumboza zonke zihlukile esimisweni sazo sokusebenza, kodwa zonke zenza i-semiconductor impahla yokumboza ifakwe ku-substrate, futhi njengempahla ye-substrate, asikho isidingo, ingaba i-semiconductor noma cha.Ukwengeza, ukumbozwa okunezici ezihlukile zikagesi nezamehlo kungalungiselelwa kokubili ukusabalalisa ukungcola kanye nokufakwa kwe-ion ebusweni be-semiconductor substrate ebangeni.Ungqimba oluncane oluvelayo lungabuye lucutshungulwe njenge-semiconductor coating ngokujwayelekile.
I-vacuum semiconductor coating iwubukhona obubalulekile ku-elekthronikhi noma ngabe okokusebenza okusebenzayo noma okungenzi lutho.Ngokuthuthuka okuqhubekayo kobuchwepheshe bokuhlanganisa i-vacuum semiconductor, ukulawulwa okunembile kokusebenza kwefilimu sekungenzeka.
Eminyakeni yamuva nje, i-amorphous coating kanye ne-polycrystalline coating yenze inqubekelaphambili esheshayo ekwakhiweni kwamadivaysi e-photoconductive, amashubhu ahlanganisiwe we-field-effect, namaseli elanga asebenza kahle kakhulu.Ngaphezu kwalokho, ngenxa yokuthuthukiswa kwe-vacuum semiconductor coating kanye nefilimu encane yezinzwa, ebuye inciphise kakhulu ubunzima bokukhethwa kwezinto ezibonakalayo futhi yenza inqubo yokukhiqiza ibe lula kancane kancane.Imishini yokuhlanganisa i-vacuum semiconductor isiphenduke ubukhona obudingekayo bezicelo ze-semiconductor.Imishini isetshenziswa kabanzi ukumboza i-semiconductor yamadivayisi wekhamera, amaseli elanga, ama-transistors ahlanganisiwe, ukuphuma kwensimu, ukukhanya kwe-cathode, ukukhishwa kwe-electron, izakhi zokuzwa ifilimu emincane, njll.
Ulayini we-magnetron sputtering coating uklanywe ngohlelo lokulawula oluzenzakalelayo ngokugcwele, isikhombimsebenzisi esibonakalayo somshini womuntu wesikrini sokuthinta esilula nesinembile.Ulayini uklanywe ngemenyu ephelele yokusebenza ukuze kuzuzwe ukuqapha okugcwele kwesimo sokusebenza sazo zonke izingxenye zomugqa wokukhiqiza, ukusethwa kwepharamitha yenqubo, ukuvikelwa kokusebenza kanye nemisebenzi ye-alamu.Lonke uhlelo lokulawula ugesi luphephile, luthembekile futhi luzinzile.Ifakwe ithagethi ye-sputtering ye-magnetron ephezulu naphansi enezinhlangothi ezimbili noma uhlelo lokuhlanganisa olunohlangothi olulodwa.
Imishini isetshenziswa kakhulu kumabhodi esekethe e-ceramic, ama-chip high-voltage capacitors nokunye ukumbozwa kwe-substrate, izindawo eziyinhloko zokufaka isicelo amabhodi wesekethe kagesi.
