Kwimveliso yanamhlanje yokugquma nge-vacuum, iimeko zokusebenza ezinomthwalo omninzi zizisa imingeni ebalulekileyo kuzinzo kunye nokungaguquguquki kokufakwa kwefilimu encinci. Njengoko iimfuno zokukhupha okuphezulu, ubungakanani obukhulu be-substrate, kunye nokugquma okuntsonkothileyo okunamaleko amaninzi kuyanda, iinkqubo zokugquma nge-vacuum—nokubaI-PVD, i-magnetron sputtering,I-ALD, okanye i-PECVD—kufuneka igcine ulawulo oluchanekileyo kwiiparamitha zenkqubo ukuqinisekisa ukufana kwefilimu, ukuphinda ivele, kunye nokuthembeka kwezixhobo ngokubanzi.
Iimeko zomthwalo ophezulu zibeka uxinzelelo olukhulu kwiimpompo ze-vacuum, izixhobo zamandla, kunye nemithombo yokubeka. Ukugcina imeko-bume ye-vacuum ephezulu kakhulu kubalulekile, njengoko naluphi na utshintsho kuxinzelelo lwesiseko lunokuchaphazela ngokuthe ngqo amazinga e-sputter, uzinzo lwe-plasma, kunye nokusebenzisana kwe-gas-phase, ekugqibeleni kuchaphazele uxinano lwefilimu, i-refractive index, kunye nokunamathela. Iinkqubo zokupompa i-vacuum eziphambili, kubandakanya iimpompo ze-turbomolecular kunye ne-cryogenic, ke ngoko zidityaniswe nokubeka esweni ngexesha langempela kunye nolawulo lwempendulo ukuze kulungiswe ukuguquguquka komthwalo wegesi okubangelwa yimithamo emikhulu ye-substrate okanye ukungeniswa kwegesi esebenzayo ngexesha leenkqubo eziphezulu.
Uzinzo lokunikezelwa kwamandla lubaluleke ngokulinganayo phantsi kokusebenza komthwalo ophezulu. Iinkqubo ze-Magnetron sputtering kunye ne-electron beam PVD zifuna uxinano lwamandla oluhambelanayo ukugcina i-plasma efanayo kunye namazinga okukhukuliseka okuzinzileyo kwethagethi. Ukuguquguquka kwe-voltage okanye yangoku kunokukhokelela ekufakweni okungalinganiyo, ukugoba, kunye nobuthi bethagethi, nto leyo ebeka emngciphekweni iipropati ze-optical zefilimu kunye nezoomatshini. Ukunciphisa le mingcipheko, imigca yokugquma yomthwalo ophezulu isebenzisa izixhobo zamandla ezilawulwa ngedijithali ngokuchonga kunye nokunciphisa i-arc, i-pulsed DC okanye i-RF modulation, kunye nokubeka esweni ngexesha langempela iiparameter zethagethi kunye ne-substrate.
Ulawulo lobushushu lolunye uphawu olubalulekileyo. Ukufakwa kwe-coating enkulu okanye enoxinano olukhulu kuvelisa ubushushu obukhulu kuzo zombini iithagethi kunye nee-substrates, nto leyo enokubangela uxinzelelo lwefilimu, ukugoba kwe-substrate, kunye neziphene zesakhiwo. Ukupholisa okusebenzayo kwee-target, izibambi ze-substrate, kunye neendonga zegumbi, kudityaniswe neprofayili yobushushu echanekileyo kunye nokubeka esweni, kuqinisekisa ukusasazwa kwamandla okufanayo, kunciphisa uxinzelelo olushiyekileyo, kwaye kugcina isakhiwo sefilimu esiphinda sivele kuzo zonke iindlela.
Inkqubo yokwenza izinto ngokuzenzekelayo kunye neenkqubo zokuxilonga ezikwindawo ethile zibalulekile ekugcineni ukusebenza okuzinzileyo. Ukubeka esweni iimpawu zeplasma ngexesha langempela, amazinga okufakwa, kunye nokufana kobukhulu kuvumela inkqubo ukuba ilungise iiparameter ngokuguquguqukayo, kubandakanya ukuhamba kwegesi, ukuguqulwa kwamandla, kunye nokujikeleza kwe-substrate, ukuze kulungiswe utshintsho olubangelwa ziimeko zomthwalo ophezulu. Olu hlobo lolawulo oluvaliweyo luthintela iimpazamo eziqokelelweyo kwimijikelo yemveliso emide kwaye luqinisekisa ukugqoka okusemgangathweni ophezulu, okuphindaphindwayo.
Ukuphathwa kwezinto nako kudlala indima ebalulekileyo. Iibhetshi ezinkulu ze-substrate okanye iithagethi ezinzima zonyusa umthwalo woomatshini kwii-manipulators kunye nee-conveyors, nto leyo ebangela ukuba kubekho ulawulo oluqinileyo lokuhamba kunye nokulungelelaniswa ngokuchanekileyo ukuze kuthintelwe ukungafaneli kokubekwa. Ukuhlanganiswa kweenkqubo zomthwalo/ukukhulula umthwalo ngokuzenzekelayo kunye neengalo zerobhothi ezichanekileyo kunciphisa ukungenelela kwabantu, kunciphisa umngcipheko wongcoliseko, kwaye kugcina inkqubo ihambelana phantsi kweemeko zokusebenza ezinzima.
Ukuqukumbela, ukugcina ukusebenza okuzinzileyo kwezixhobo zokugquma nge-vacuum phantsi kweemeko zomthwalo ophezulu kufuna indlela edibeneyo, edibanisa iteknoloji yokugquma ephucukileyo, ulawulo lwamandla oluchanekileyo, ulawulo olusebenzayo lobushushu, ukuxilongwa kwenkqubo ngexesha langempela, kunye nokuphathwa kwezinto ngokuzenzekelayo. Ngokwenza ngcono ezi zinto, iinkqubo zokugquma zinokubonelela ngeefilimu ezibhityileyo ezifanayo nezisemgangathweni ophezulu nakwiindawo zemveliso ezinzima, zixhasa ukuveliswa kwemveliso ephezulu ngelixa ziqinisekisa ukuthembeka, ukuphinda kuvele, kunye nokusebenza kakuhle kwenkqubo.
