Kwiinkqubo zanamhlanje zokugquma nge-vacuum, umthombo we-ion udlala indima ebalulekileyo njengeyunithi encedisayo ebalulekileyo kwaye usetyenziswa kakhulu kwi-PVD (Physical Vapor Deposition) kunyeugqubuthelo olubonakalayoamasimi. Ayichaphazeli nje kuphela uxinano kunye nokunamathela komaleko wokugquma kodwa ikwachaphazela ngokuthe ngqo ukuhambelana kwemveliso kunye nemveliso. Ngoko ke, yintoni kanye kanye indima yomthombo we-ion kwinkqubo yokugquma? Iyintoni umgaqo wayo osebenzayo? Eli nqaku liza kubonelela ngohlalutyo oluneenkcukacha.
Yintoni i-Ion Source?
Umthombo we-ion sisixhobo esivelisa kwaye sikhawulezise ii-ion kwindawo engenamoya. Ngeendlela ezifana nokukhupha i-plasma kunye nokuqhushumba kwegesi engathathi hlangothi, umthombo we-ion ukhupha imisebe ye-ion enamandla aphezulu, enokunxibelelana nomphezulu we-substrate okanye umaleko wefilimu okhulayo ukuze wenze imisebenzi emininzi, njengokucoca, ukunceda ukubekwa, kunye nokuphucula ukunamathela.
Iindidi eziqhelekileyo zemithombo ye-ion ziquka: Umthombo we-Thermionic Ion; Umthombo we-Hollow Cathode Ion; Umthombo we-Multipole Ion (osetyenziswa rhoqo kuncedo olusebenzisa amandla aphantsi); Imisebenzi ephambili yoMthombo we-Ion
1. Unyango lwangaphambi konyango lwe-substrate: Ukuphucula ukunamathela
Ngaphambi kokuba ibekwe, umphezulu we-substrate uhlala uqulathe ii-oxides, izinto ezingcolisayo eziphilayo, kunye nezinye izinto ezingcolileyo. Ukusebenzisa umthombo we-ion kwi-Ion Cleaning kunokususa ngempumelelo ezi zinto zingcolisayo kumphezulu, kuphucule amandla okubopha phakathi kwefilimu kunye ne-substrate. Xa kuthelekiswa neendlela zemveli zokucoca, ukucoca imisebe ye-ion kunika iingenelo ezifana nokungabi nakuthinta, ukungatshabalalisi, kunye nokusebenza kakuhle.
2. Ukuncedisa ekuHlaziyweni: Ukuphucula uLwakhiwo lweFilimu
Ngexesha lenkqubo yokubeka, umqadi we-ion ungasebenza “njengomthombo wamandla oncedisayo” ukuphucula amandla okufuduka kweeathom zeeathom ngexesha lokukhula kwefilimu. Oku kukhokelela ekwakhiweni kweefilimu ezixineneyo, ezizinzileyo, nezifanayo. Oku kubaluleke kakhulu kwiingubo ezibonakalayo, iingubo eziqinileyo, kunye nezinye izicelo apho kufuneka khona uxinano oluphezulu kunye noxinzelelo oluphantsi.
3. Ukulawula Uxinzelelo lweFilimu kunye neMofology yomphezulu
Ngokulungisa amandla kunye ne-engile ye-ion beam, uxinzelelo lwangaphakathi, ubungakanani bengqolowa, kunye nobunzima obuncinci befilimu bunokulawulwa ngokufanelekileyo. Umzekelo, ekulungiseleleni iifilimu zokuphazamiseka kwe-multilayer okanye iifilimu ze-optical ezichanekileyo kakhulu, uncedo lomthombo we-ion lunokuthintela iziphene eziqhelekileyo ezifana "neemingxuma zepinki" kunye "ne-delamination," ukuphucula ukuhambelana kunye nokuqina kwefilimu.
4. Ukuphucula ukuQiniseka kokuGcoba kunye nokuNika
Ngoncedo lomthombo we-ion, isakhiwo sokugquma esifanayo sinokufezekiswa kwiindawo zokusebenza ezinkulu, ingakumbi ezo zineendawo ezigobileyo okanye iiglasi ezinkulu kunye neeplastiki zokugquma ezibonakalayo. Oku kunceda ukuphucula isivuno kunye nolawulo lokuphindaphindeka kwimveliso yobuninzi.
Imizekelo yesicelo semithombo ye-Ion kwiinkqubo ezisebenzayo
Ukubekwa kweFilimu yokukhanya: Ukuphucula iipropati zokukhanya kunye nokunamathela kweefilimu ezichanekileyo ezifana neengubo ezichasene nokukhanya, iifilimu ezibonisa ukukhanya okuphezulu, kunye nezihluzi zokukhanya.
Ukulungiswa Kokugquma Okuqinileyo: Ukuphucula uxinano lwefilimu kunye nokusebenza kwayo okuchasene nokukrazuka kwiinkqubo zefilimu ezinobunzima obuphezulu ezifana neDLC (Diamond-Like Carbon), TiN, kunye neCrN.
Iingubo Zangaphakathi Zeemoto: Phucula ukuhambelana kombala kunye nokunamathela kwengubo, yandisa ubomi benkonzo.
Unyango Lomphezulu Wezinto Ze-elektroniki: Qinisekisa uzinzo lwesakhiwo sefilimu encinci kunye nokusebenza kwayo rhoqo.
Umthombo we-ion yinxalenye "eyongeziweyo" ebalulekileyo kwiinkqubo zokugquma zanamhlanje. Ngokwazisa ukuhamba kwe-ion enamandla aphezulu okulawulwayo, idlala indima ebalulekileyo kumanqanaba ahlukeneyo enkqubo yokufaka ifilimu. Nokuba kukuphucula ukunamathela, ukwenza ngcono ulwakhiwo, ukulawula uxinzelelo, okanye ukuphucula ukuhambelana, umthombo we-ion unika inkxaso enamandla yokufezekisa ukugquma okusemgangathweni ophezulu nokusebenza kakuhle.
Njengoko iimfuno zokusebenza ziqhubeka nokwanda kwiindawo ezifana neziboniso ze-optical, i-electronics echanekileyo, kunye nokuveliswa kweemoto, ukuveliswa kweteknoloji ye-ion source kuya kuba yinxalenye ebalulekileyo yokuqhubela phambili iinkqubo zokugquma i-vacuum ukuya kumanqanaba aphezulu.
