Ezinqubweni zesimanje zokumboza nge-vacuum, umthombo we-ion udlala indima ebalulekile njengeyunithi yokusiza ebalulekile futhi usetshenziswa kabanzi ku-PVD (Physical Vapor Deposition) kanyeisembozo se-opticalamasimu. Akugcini nje ngokuthonya ubuningi kanye nokunamathela kwesendlalelo sokumboza kodwa futhi kuthinta ngqo ukuhambisana komkhiqizo kanye nokukhiqiza. Ngakho-ke, iyini ngempela indima yomthombo we-ion enqubweni yokumboza? Iyini isimiso sayo sokusebenza? Lesi sihloko sizohlinzeka ngokuhlaziywa okuningiliziwe.
Uyini Umthombo we-Ion?
Umthombo we-ion uyithuluzi elikhiqiza futhi lisheshise ama-ion endaweni engenamoya. Ngezindlela ezifana nokukhishwa kwe-plasma kanye nokuqhuma kwegesi okungathathi hlangothi, umthombo we-ion ukhipha imisebe ye-ion enamandla aphezulu, engasebenzisana nomphezulu we-substrate noma ungqimba lwefilimu olukhulayo ukuze lwenze imisebenzi eminingi, njengokuhlanza, ukusiza ukufakwa, kanye nokuthuthukisa ukunamathela.
Izinhlobo ezivamile zemithombo ye-ion zifaka: Umthombo we-Thermionic Ion; Umthombo we-Hollow Cathode Ion; Umthombo we-Multipole Ion (ovame ukusetshenziselwa usizo olusebenzisa amandla amancane); Imisebenzi Eyinhloko Yomthombo we-Ion
1. Ukwelashwa Kwangaphambi Kwe-Substrate: Ukuthuthukisa Ukunamathela
Ngaphambi kokufakwa, ubuso be-substrate buvame ukuqukatha ama-oxide, ukungcola okungokwemvelo, kanye nokunye ukungcola. Ukusebenzisa umthombo we-ion we-Ion Cleaning kungasusa ngempumelelo lokhu kungcola okungaphezulu, kuthuthukise amandla okubopha phakathi kwefilimu ne-substrate. Uma kuqhathaniswa nezindlela zokuhlanza zendabuko, ukuhlanza imisebe ye-ion kunikeza izinzuzo ezifana nokungenakuthinta, ukungabhubhisi, kanye nokusebenza kahle okuphezulu.
2. Ukusiza Ukubeka: Ukuthuthukisa Isakhiwo Sefilimu
Ngesikhathi senqubo yokufaka, umsebe we-ion ungasebenza “njengomthombo wamandla osizayo” ukuthuthukisa ikhono lokufuduka kwama-athomu lama-athomu ngesikhathi sokukhula kwefilimu. Lokhu kuholela ekwakhekeni kwamafilimu aminyene, azinzile, futhi afanayo. Lokhu kubaluleke kakhulu ekumbozweni okubonakalayo, ekumbozweni okuqinile, nakwezinye izinhlelo zokusebenza lapho kudingeka khona ukuminyana okuphezulu kanye nokucindezeleka okuphansi.
3. Ukulawula Ukucindezeleka Kwefilimu kanye Nokwakheka Komphezulu
Ngokulungisa amandla kanye ne-engeli ye-ion beam, ukucindezeleka kwangaphakathi, usayizi wezinhlamvu, ngisho nokuqina okuncane kwefilimu kungalawulwa ngempumelelo. Isibonelo, ekulungiseleleni amafilimu okuphazamisana anezingqimba eziningi noma amafilimu okukhanya anemba kakhulu, usizo lomthombo we-ion lungavimbela amaphutha avamile njenge-"pinholes" kanye ne-"delamination," okuthuthukisa ukuhambisana nokuqina kwefilimu.
4. Ukuthuthukisa Ukunamathelana Nokukhiqiza
Ngosizo lomthombo we-ion, isakhiwo sokumboza esifanayo singatholakala ezindaweni zokusebenza ezinkulu, ikakhulukazi lezo ezinezindawo ezigobile eziyinkimbinkimbi noma izingxenye ezinkulu zengilazi nepulasitiki zokumboza okubonakalayo. Lokhu kusiza ekuthuthukiseni ukukhiqizwa kanye nokulawulwa kokuphindaphinda ekukhiqizweni okukhulu.
Izimo Zokusetshenziswa Kwemithombo Ye-Ion Ezinqubweni Ezisebenzayo
Ukufakwa Kwefilimu Ebonakalayo: Thuthukisa izakhiwo zokukhanya kanye nokunamathela kwamafilimu anembile njengezembozo ezivimbela ukukhanya, amafilimu abonisa ukukhanya okuphezulu, kanye nezihlungi zokukhanya.
Ukulungiselela Ukubopha Okuqinile: Thuthukisa ubuningi befilimu kanye nokusebenza okulwa nokuqhekeka kwesikhumba ezinhlelweni zefilimu ezinokuqina okuphezulu njenge-DLC (Diamond-Like Carbon), i-TiN, kanye ne-CrN.
Izembozo Zangaphakathi Zezimoto: Thuthukisa ukuhambisana kombala kanye nokunamathela kwesembozo, kwandise impilo yesevisi.
Ukwelashwa Komphezulu Wezingxenye Ze-elekthronikhi: Qinisekisa ukuqina kwesakhiwo sefilimu encane kanye nokusebenza kwemvamisa ephezulu.
Umthombo we-ion uyingxenye "eyengezwe inani" ebalulekile ezinhlelweni zokumboza zesimanje. Ngokungenisa ukugeleza kwe-ion okulawulekayo okunamandla aphezulu, kudlala indima ebalulekile ezigabeni ezahlukene zenqubo yokufaka ifilimu. Kungakhathaliseki ukuthi kuthuthukisa ukunamathela, ukwenza ngcono isakhiwo, ukulawula ukucindezeleka, noma ukuthuthukisa ukuhambisana, umthombo we-ion unikeza ukwesekwa okuqinile kokufeza izembozo ze-vacuum ezisezingeni eliphezulu nezisebenza kahle.
Njengoba izidingo zokusebenza ziqhubeka nokwanda emikhakheni efana nokubonisa okubonakalayo, i-elekthronikhi enembile, kanye nokukhiqizwa kwezimoto, ukusungulwa kobuchwepheshe bomthombo we-ion nakho kuzoba yimbangela ebalulekile yokuthuthukisa izinqubo zokugqoka i-vacuum zibe amazinga aphezulu.
