Eli nqaku libonelela ngohlalutyo oluneenkcukacha lokwahlulwahlulwa kunye nobubanzi bokusetyenziswa kwezixhobo zokugquma nge-vacuum, kunye nenkcazo emfutshane yemigaqo yazo, ukukunceda wenze ukhetho lwesayensi ngakumbi ekukhetheni iinkqubo zokugquma.
Imigaqo esisiseko yeNombolo 1 Ukwaleka ngeVacuum
Ugquma lwe-vacuum lubhekisa kwinkqubo yokuguqula izinto zibe yi-vapor okanye i-plasma states ngeendlela zomzimba okanye zeekhemikhali kwindawo ene-vacuum ephezulu kwaye zibekwe kwiindawo ezingaphantsi komhlaba ukuze zenze iifilimu ezincinci. Iingenelo zayo eziphambili ziquka iileya zefilimu ezixineneyo, ukunamathela okuqinileyo, ubunyulu obuphezulu, kunye nokuhambelana nonyango oluhlukeneyo lomphezulu wezinto.
Ingubo ye-vacuum yahlulwe kakhulu kwiindidi ezimbini: i-Physical Vapor Deposition (PVD) kunye ne-Chemical Vapor Deposition (CVD), kunye nezixhobo ezithile ezihlelwe ngakumbi ngokweendlela zenkqubo.

Inkqubo yokuphuma komoya nge-e-beam
Umgaqo: Imisebe ye-electron enamandla aphezulu ihlasela izinto ekujoliswe kuzo, nto leyo ebangela ukunyibilika kunye nokufuma kwindawo ethile, nto leyo egcina phezu komphezulu we-substrate.
Ububanzi bokusetyenziswa: Ukugquma izinto ezinyibilikayo kakhulu (umz., Ti, W, SiO₂), ezisetyenziswa kakhulu kwi-precision optics, kwiinkqubo zefilimu ezinee-multilayer, kunye neefilimu ezincinci ezisebenzayo.
Iimpawu: Ukusebenza kakuhle kokufuma, ukusetyenziswa okuphezulu kwezinto, kunye nobunyulu obuhle kakhulu befilimu.
Inkqubo yokutshiza iMagnetron
Umgaqo: Ii-ions kwi-plasma zihlasela izinto ekujoliswe kuzo, nto leyo ebangela ukuba ii-athomu “zitshizwe” kwi-substrate kwinqanaba le-athomu.
Ububanzi bokusetyenziswa: Iingubo eziqinileyo (umz., iTiN, iCrN), iifilimu ze-semiconductor, iiphaneli zokuchukumisa, iifilimu ezithambileyo zelanga, njl.njl.
Iimpawu: Iileya zefilimu ezifanayo, ukunamathela okuqinileyo, ukulawuleka okuphezulu, ezifanelekileyo kwiindawo ezinkulu nezinobume obuntsonkothileyo.
Inkqubo yeCVD
Umgaqo: Iigesi ezisebenzayo zifumana iimpembelelo zeekhemikhali kubushushu obuphezulu, zivelisa iimveliso zokubeka izinto kumphezulu we-substrate.
Ububanzi bokusetyenziswa: Ukulungiswa kweefilimu ezisebenzayo zezixhobo ze-semiconductor, i-silicon carbide (SiC), i-silicon nitride (Si₃N₄), njl.
Iimpawu: Ifikelela kwi-equipment efanayo, enoxinano olukhulu, kwaye inokwakheka okuntsonkothileyo, ifanelekile kwizicelo ezichanekileyo.
Inkqubo ye-Plasma-Enhanced CVD (PECVD)
Umgaqo: Ingenisa i-RF plasma ukuze ivuselele iigesi ezisabelayo, yenze iifilimu ezincinci kumaqondo obushushu aphantsi.
