Mu ikoranabuhanga rigezweho ryo gusiga irangi ry’amashanyarazi, kugenzura ingufu z’amashanyarazi ni ikintu cy’ingenzi kigira ingaruka ku buryo butaziguye ku miterere y’icyuma gito, ubucucike, imbaraga z’imbere mu mubiri, n’imbaraga zo gufatana. Haba mu bikoresho bikomeye, mu bikoresho byo gushushanya, cyangwa mu bikoresho by’amatara, kugenzura neza ingufu z’amashanyarazi y’icyuma ntabwo bihindura gusa imiterere ya plasma, ahubwo binanongera imikorere n’ubwizigirwa bwa filimi zivuyemo.
No.1 Kugenzura Voltage Bias ni iki?
Kugenzura amashanyarazi ashingiye ku ruhande rumweyerekeza ku buryo bwo gushyira imbaraga mbi ku gice cy’ubutaka mu gihe cyo gushyiramo ibintu, bigatuma kiba hasi cyane ugereranyije n’amaraso akikije plasma. Ubu buryo bukoreshwa cyane mu buryo bwa PVD (Physical Vapor Deposition), cyane cyane mu gukoresha magnetron sputtering, ion plating, na cathodic arc deposition systems.
Ubusumbane bw’ingufu bushobora gukoreshwa binyuze mu gutanga ingufu za DC (Direct Current), MF (Mid-Frequency), cyangwa RF (Radio Frequency). Inshingano zayo z’ibanze ni ukwihutisha iyoni nziza muri plasma zigana ku buso bwa substrate, bigatuma iyoni ikwirakwira mu buryo butuma filime ikura neza.
No.2 Uburyo Umuvuduko w'Ingufu Ubangamira Imiterere ya Filimi
Uburyo bw'ibanze bwo kugenzura ingufu z'amashanyarazi buri mu guhindura uburyo filime ikuramo binyuze mu ngufu za iyoni zinjira. Ingaruka zayo zigaragarira mu bintu byinshi by'ingenzi:
Ubucucike:
Ubwiyongere bukwiye bw'ibice bibi byongera ingufu za kinetiki za iyoni zigera kuri substrate, bigateza imbere kugenda kw'ubuso no kongera gutunganya adatomu. Ibi bituma habaho filime zicucitse kandi zirwanya ingese, gukomera no kudashira.
Kugenzura Imihangayiko:
Gutera iron bias nabyo bitera stress isigaye muri firime. Bias nyinshi zishobora gutera stress ikomeye, ishobora gutera gucika cyangwa gucika. Kubwibyo, urwego rwiza rw'ibice bigomba gutoranywa neza hashingiwe ku bikoresho bya firime, ubwoko bwa substrate, n'ubugari bwa palace.
Kongera uburyo bwo gufatana:
Umuvuduko w’amashanyarazi ushingiye ku bias wongera imikoranire hagati y’ibice byombi binyuze mu guteza imbere kuvanga ibice cyangwa gukora imiyoboro ishingiye ku bipimo, bityo bikanoza gufatana kwa filime n’ibice by’inyuma—cyane cyane ku bifuniko bikomeye cyangwa imiterere myinshi.
Kugabanya uduce duto no Gutunganya Ubuso:
Guhitamo neza bishobora kugabanya ukwinjira mu duce duto tw’urusobe rw’ibintu no kugabanya ubukana bw’ubuso, bityo bikagabanya igihombo cyo gukwirakwira mu mashusho y’urusobe rw’ibintu kandi bikanoza ubwiza bw’ubuso.
Ubwoko bwa 3 bw'uburyo bwo kugenzura uruhande rushingiye ku ruhande
DC Bias: Ikoreshwa cyane mu bikoresho biyobora amashanyarazi, itanga uburyo bworoshye bwo kugenzura no gusubiza vuba. Isanzwe mu bikoresho bishushanya n'ibikomeye.
RF Bias: Ni nziza ku bikoresho bidatwara amashanyarazi nk'ibirahure, keramike, na polimeri. Itanga uburyo bwinshi bwo guhuza ibikoresho ariko isaba uburyo buhanitse bwo guhuza sisitemu no gutunganya imikorere.
Gushyiramo imbaraga mu kirere: Bikubiyemo gukoresha ingufu zipima ikirere, kuringaniza igipimo cyo gushyiramo ingufu n'ingufu za iyoni. Bikwiriye cyane ku bifuniko biri mu bushyuhe buke cyangwa imiterere y'ikirere igoye.
Byongeye kandi, sisitemu zimwe na zimwe zigezweho zikoresha uburyo bwo kugenzura imiterere ya plasma n'umuyoboro wa bias mu gihe nyacyo kugira ngo zigumane uburyo buhoraho bwo gukora no kwemeza ko gutwikira ibintu bihuye mu byiciro byose.
