Sida aynu wada ognahay, qeexida semiconductor waa in ay leedahay conductivity u dhexeeya kirishbooyada qalalan iyo insulators, iska caabin u dhexeeya biraha iyo insulator, taas oo inta badan waa heerkulka qolka waa inta u dhaxaysa 1mΩ-cm ~ 1GΩ-cm. Sanadihii la soo dhaafay, daahan vacuum semiconductor ee shirkadaha waaweyn ee semiconductor, waa cadahay in ay xaalad waa sii kordheysa sare, gaar ahaan in qaar ka mid ah hababka cilmi baarista wareegga horumarinta baaxadda weyn nidaamka in qalabka beddelka magnetoelectric, qalabka iftiimiya iyo shaqada kale ee horumarinta.Dahaarka Vacuum semiconductor wuxuu leeyahay door muhiim ah.
Semiconductors waxaa lagu gartaa sifooyinkooda gudaha, heerkulka iyo feejignaanta wasakhda.Alaabta daahan semiconductor Vacuum waxaa lagu kala soocaa midba midka kale inta badan xeryahooda ka kooban.Ku dhawaad dhammaan waxay ku saleysan yihiin boron, carbon, silicon, germanium, arsenic, antimony, tellurium, iodine, iwm, iyo qaar aad u yar GaP, GaAs, lnSb, iwm. MnO, Cr₂O₃, Cu₂O, iwm.
Uumi-baxa vacuum, daahan sputtering, daahan ion iyo qalab kale samayn karaa vacuum semiconductor daahan.Qalabkan dahaarka ah dhamaantood way ka duwan yihiin mabda'a shaqada, laakiin dhammaantood waxay sameeyaan sheyga daahan semiconductor ee lagu dhejiyo substrate-ka, iyo sida walxaha substrate-ka, ma jirto wax shuruud ah, waxay noqon kartaa semiconductor ama maya.Intaa waxaa dheer, dahaarka leh sifooyinka korantada iyo indhaha kala duwan waxaa lagu diyaarin karaa labadaba faafinta wasakhaysan iyo ion ku dhejinta dusha sare ee substrate-ka semiconductor ee kala duwan.Lakabka khafiifka ah ee ka soo baxa ayaa sidoo kale loo farsameyn karaa sida daboolka semiconductor guud ahaan.
Dahaarka Vacuum semiconductor waa joogitaanka lagama maarmaanka ah ee elektiroonigga haddii ay tahay aaladaha firfircoon ama kuwa dadban.Iyadoo horumarinta joogtada ah ee tignoolajiyada daahan semiconductor vacuum, xakamaynta saxda ah ee waxqabadka filimku wuxuu noqday suurtogal.
Sanadihii la soo dhaafay, dahaarka amorphous iyo daboolka polycrystalline ayaa horumar degdeg ah ka sameeyay soo saarista aaladaha sawir-qaadista, tuubooyinka-saamaynta duurka ee daboolan, iyo unugyada qorraxda waxtarka leh.Intaa waxaa dheer, sababtoo ah horumarinta daahan semiconductor vacuum iyo filimka khafiifka ah ee dareemayaasha, taas oo sidoo kale si weyn u yaraynaysaa dhibka xulashada alaabta oo ka dhigaysa habka wax soo saarka si tartiib tartiib ah la fududeeyay.Qalabka dahaarka ee Vacuum semiconductor wuxuu noqday joogitaanka lagama maarmaanka u ah codsiyada semiconductor.Qalabka waxaa si weyn loogu isticmaalaa daahan semiconductor ee qalabka kamaradaha, unugyada qoraxda, transistors dahaarka leh, qiiqa garoonka, cathode-light, qiiqa elektarooniga ah, walxaha dareenka film khafiif ah, iwm.
Xariiqda dahaarka ee magnetron-ka waxaa loogu talagalay nidaam kontorool oo toos ah, oo ku habboon oo dareen leh shaashadda bini-aadmiga mashiinka mashiinka.Khadka waxaa loogu talagalay menu shaqo oo dhammaystiran si loo gaaro kormeer buuxa oo ku saabsan xaaladda hawlgalka ee dhammaan qaybaha khadka wax soo saarka, dejinta cabbirka nidaamka, ilaalinta hawlgalka iyo hawlaha digniinta.Nidaamka xakamaynta korantada oo dhan waa badbaado, la isku halayn karo oo deggan.Ku qalabaysan sare iyo hoose oo laba-geesood ah magnetron bartilmaameed ama nidaamka daahan hal dhinac ah.
Qalabka waxaa inta badan lagu dabaqaa looxyada wareegga dhoobada, chip capacitors-voltage capacitors iyo daahan kale substrate, meelaha ugu muhiimsan ee codsiga waa loox wareegga elektarooniga ah.
