Mu gutwikira umwuka uva mu kirere, kugenzura ikirere ni kimwe mu bintu by'ingenzi bigira ingaruka ku bwiza bwa firime no ku buryo ibintu bihora bihagaze. Nubwo icyumba cyo gutwikira gikorera munsi y'umwuka uva mu kirere, ahantu ho gutwikira umwuka si ahantu "hatagira gazi" burundu. Imyuka isigaye, imyuka ikoreshwa mu buryo bw'umwuka, imyuka ikora, urujya n'uruza rw'umwuka, umuvuduko w'akazi, n'imiterere y'imashini zitanga umwuka bihora bigirana isano n'ubwoko bwa plasma n'ubwo gutwikira umwuka.
Mu musaruro nyawo, inenge nyinshi zo gutwikira zisa n’izifitanye isano n’intego, cathode, substrate, cyangwa amashanyarazi zishobora gukurikirwa no kugenzura ikirere kidahindagurika. Ibibazo nk'ibara ridahindagurika rya firime, gufata nabi, ubushobozi budasanzwe bwo guhangana na firime, guhagarara cyane, ubugari butaringaniye bwa firime, imyobo, no guhinduka kw'itsinda rimwe na rimwe akenshi bifitanye isano rya bugufi n'impinduka mu mwuka w'imikorere.
Kubwibyo, kuri sisitemu za PVD z’inganda, kugenzura ikirere ntibigomba gufatwa nk’uburyo bwo guhindura ikigereranyo cy’umuvuduko wa gaze. Ni inzira ihuriweho irimo umuvuduko w’ibanze, imiterere ya gaze isigaye, umuvuduko w’imikorere ya gaze, umuvuduko w’imikorere, umuvuduko w’igice cya gaze, uburyo bwo kohereza amazi mu kirere, imiterere ya plasma, n’uburyo gaze igaruka.
1. Intambwe ya Mbere Si Ugutera Gazi, Ahubwo Ni Ukugenzura Imashini Ikoresha Gazi
Ikosa rikunze kugaragara mu musaruro ni ukwibanda ku bipimo bya process-gaz mu gihe wirengagiza imiterere y'icyumba cy'imyanda ubwacyo.
Mbere yo gushyiramo imyuka ikoreshwa mu gutunganya ibintu, icyumba cyo gutwikira kigomba kugera ku gipimo cy’umuvuduko ukwiye w’ibanze. Umuvuduko muto uhagije w’ibanze ufasha kugabanya ogisijeni isigaye, umwuka w’amazi, karubone, n’ibindi bintu bihumanya. Iyi myuka isigaye ishobora kugira uruhare mu gikorwa cyo kuyishyira mu ruganda rukura, ibyo bikaba bigira ingaruka ku miterere ya filime, imiterere mito, gufatana kwayo, n’imiterere y’amashanyarazi cyangwa iy’amashanyarazi.
Ibi ni ingenzi cyane cyane ku mikorere ya PVD ikora neza. Urugero, iyo ushyira nitrides cyangwa oxydes, umwuka ukoreshwa ugomba gutandukanywa na ogisijeni idacungwa cyangwa umwuka w'amazi usigaye mu cyumba. Bitabaye ibyo, ikirere nyacyo gishobora gutandukana cyane n'uburyo bwo gukora nubwo icyuma gipima ubwinshi bw'amazi kiba gikora neza.
Mu musaruro ufatika, iyo resept imwe itanze ibisubizo bitandukanye mu buryo butunguranye, ikibazo cya mbere ntikigomba kuba buri gihe niba imbaraga z’intego zarahindutse. Ni ngombwa kandi kugenzura niba umuvuduko w’ibanze, igihe cyo kugabanya imashini, isuku y’icyumba, n’imiterere ya gaze isigaye byarahindutse.
2. Imyitwarire yo gukamura ni ikimenyetso cy'ingenzi cy'inzira
Sisitemu nziza yo gusohora umwuka igomba kugira imiterere ihamye kandi ishobora gusubirwamo yo kugabanya amazi.
Iyo icyumba gifata igihe kirekire kuruta uko bisanzwe kugira ngo kigere ku gipimo cy’umuvuduko w’ibanze gikenewe, ibi bishobora kugaragaza ko imyuka isohoka yiyongera, umwanda, amazi asohoka mu cyuma gishyushye, imikorere ya pompe yangiritse, cyangwa ubushuhe bwinshi mu cyumba.
Inkomoko isanzwe y’imyuka isohoka irimo ibikoresho bya substrate, ibikoresho, ibisigazwa bya polymer, amavuta akoreshwa mu byuma bisukura, ubuso bw’icyumba cyanduye, n’ubushuhe bwinjira mu byuma. Hari ibikoresho bishobora gukomeza kurekura imyuka nyuma y’uko icyumba kigeze ku gitutu gisa n’aho gikwiye, bigatuma habaho imiterere idahindagurika mu gihe cyo gushyiramo imyanda.
Kubwibyo, isano iri hagati y'igihe cyo kugabanya ingufu, umuvuduko wa nyuma, umuvuduko uzamuka, n'uburyo ibintu bihagaze bishobora gutanga amakuru y'ingirakamaro ku miterere y'uburyo bwo gusohora umwuka mu buryo butari ubwawo.
Ku bikoresho bikoreshwa mu gukora, gukurikirana imyitwarire y’umuvuduko uzamuka nyuma yo kwitandukanya na sisitemu yo kuvoma bishobora no gufasha gutandukanya amazi aturuka mu kirere n’ibyuka bisanzwe bisohoka. Ibi ni ingirakamaro cyane cyane mu gihe cyo gukemura ibibazo.
3. Umuvuduko w'akazi ugena ibidukikije by'ubwikorezi
Nyuma yo kubona ifu ikwiye yo gufunga umwuka, umwuka ukoreshwa mu gutunganya gazi ushyirwa mu mwanya wayo, hanyuma icyumba kikinjira mu mwanya wo gukora.
Umuvuduko w'imikorere ugira ingaruka zitaziguye ku nzira y’ubusa y’atome, iyoni, na electroni zirimo gutonyanga. Bityo, bigira ingaruka ku miterere ya plasma, igipimo cyo gushyiramo, ionization, gukwirakwira kw'uduce, ndetse n'uburyo uruziga rw'ingunguru rukwirakwira.
Iyo igitutu kiri hasi, ubwoko bw’ibinyabuzima bifite amacandwe bushobora kunyura mu cyumba cy’amazi ariko bikagongana gake, bigatuma habaho uruziga rw’amazi mu cyerekezo kimwe. Ibi bishobora kugira akamaro kuri bimwe mu bikorwa ariko bishobora kongera ingaruka z’igicucu ku bice bikomeye by’impande eshatu.
Uko umuvuduko w’amazi wiyongera, ni ko guhura kw’ibintu biri mu mazi n’ibintu biri mu mazi bigenda byiyongera. Ukwiyongera kw’amazi mu mazi kugenda gukwirakwira cyane, bishobora kunoza uburyo bwo gutwikira ibintu ku buso bufunze ariko bishobora no kugabanya imikorere y’amazi no guhindura imiterere y’amafilimi.
Bityo rero, igitutu cy’akazi ntigikwiye gufatwa nk'agaciro gakwiye "gushyirwaho neza." Ni impinduka y’imikorere igira ingaruka zitaziguye ku mikorere y’ubwoko bw’ibimera bitwikiriye.
4. Ihindagurika ry'umwuka n'umuvuduko wabyo si kimwe
Mu mikorere ya PVD ifatika, urujya n'uruza rwa gazi rugenzurwa hakoreshejwe uburyo bwo kugenzura urujya n'uruza rw'amazi (MFC), mu gihe igitutu cy'icyumba kigenwa n'uburinganire hagati y'ingufu zinjira n'ubushobozi bwo kuvoma.
Iri tandukaniro ni ingenzi cyane.
Igipimo kimwe cy’umuvuduko wa gazi ntigitanga umuvuduko umwe w’akazi mu bihe bitandukanye bya sisitemu y’umwuka. Iyo umuvuduko wo gupompa, aho amashanyarazi anyura, aho amashanyarazi anyura, cyangwa inzira y’imbere y’umwuka inyura, umuvuduko uvamo na wo ushobora guhinduka.
Urugero, niba valve yo kugosora cyangwa sisitemu yo kuvoma ikora nabi, umukoresha ashobora kongera urujya n'uruza rwa gaze kugira ngo yishyure ihinduka ry'umuvuduko. Nubwo umuvuduko ushobora kugaruka by'agateganyo ku gaciro kagenwe, imiterere nyayo y'urujya n'uruza rwa gaze n'amaraso bishobora kuba byarahindutse.
Kubwibyo, abahanga mu by’imikorere muri rusange bakurikirana urujya n’uruza rw’umwuka n’umuvuduko w’icyumba hamwe, aho gukoresha ibipimo byombi mu buryo bwihariye nk’icyitegererezo cy’urujya n’uruza rw’ibintu.
5. Kugenzura gazi ikoreshwa mu buryo bwihuse birushaho kuba byiza
Ku bijyanye n'imikorere ya PVD ikora nka TiN, CrN, TiAlN, Al₂O₃, SiO₂, n'izindi coating, kugenzura ikirere biragorana cyane.
Imyuka ikora neza igira uruhare mu buryo butaziguye mu ikorwa rya firime. Azote, ogisijeni, asetilini, methane, cyangwa indi myuka ikora neza ishobora gukorana n'ubwoko bwavuye mu mwuka cyangwa bwacitsemo uduce kugira ngo hamenyekane imiterere ya nyuma ya firime.
Impinduka nto mu gitutu cy’ingufu zikomoka kuri gaze ishobora guteza impinduka ikomeye mu miterere ya firime.
Urugero, umuvuduko uhagije wa azote ushobora gutuma habaho nitridation idahagije, mu gihe azote irenze urugero ishobora kugira ingaruka ku muvuduko wo kwishyira mu kirere, imiterere ya plasma, imyitwarire y’intego, n’imiterere ya firime. Mu gutera magnetron ikora, kwiyongera cyane kwa gaze ishobora no gutera uburozi bw’intego, aho urwego rw’inyongera rukora ku buso bw’intego kandi rugahindura imiterere y’intego.
Niyo mpamvu gukoresha uburyo bwo gusohora amazi mu buryo bwihuse akenshi bisaba kugenzura uburyo bwo gukora ibintu buhambaye kuruta gukoresha icyuma gisanzwe.
6. Uburozi bwo mu bwoko bwa "Target Poisoning" ni ikibazo gisanzwe cyo kugenzura ikirere
Mu kuvura magnetron hakoreshejwe uburyo bwa reactive, uburozi bwo mu bwoko bwa target ni kimwe mu bibazo bikunze kugaragara mu kugenzura ikirere.
Iyo igitutu cy'igice cy'umwuka utera imbaraga kirenze urugero runaka, ubuso bw'ikintu bushobora gutwikirwa n'urwego rw'ikintu kimwe. Hanyuma icyo kintu kiva mu buryo bw'icyuma kijya mu buryo bw'uburozi.
Iri hinduka rishobora guteza impinduka mu muvuduko wo gusohora, ingufu zisohora, umuvuduko wo gusohora, imyuka ya elegitoroniki ya kabiri, umuvuduko wo gushyiramo, n'imiterere ya firime.
Ikibazo kirushaho kugorana kuko isano iri hagati y’urujya n’uruza rw’imyuka ikora neza n’imiterere y’intego akenshi iba idahuje n’umurongo umwe. Impinduka nto mu rujya n’uruza rw’imyuka ishobora guteza impinduka nini cyane mu miterere y’urujya n’uruza rw’imyuka.
Ku musaruro mwinshi, kwishingikiriza gusa ku muvuduko uhoraho wa gaze ishobora kuba idahagije. Sisitemu zigezweho zishobora gukoresha uburyo bwo kugenzura bufunganye bushingiye ku ibyuka bisohora urumuri, imiterere y’ibisohoka, gupima igitutu cy’igice, cyangwa ibindi bimenyetso by’imikorere kugira ngo bihamye idirishya ry’ibyuka bifungura.
7. Isuku y'icyumba igira ingaruka zitaziguye ku buryo ikirere gihagaze neza
Kugenzura ikirere ntibishingira gusa ku buryo bwo gutanga gazi. Imiterere y'imbere y'icyumba gikingira ni ingenzi cyane.
Mu gihe cy’ibikorwa bisubirwamo, ibikoresho byo gusiga bigenda byirundanya ku nkuta z’icyumba, ku birindiro, ku bikoresho bya substrate, n’ibindi bice by’imbere. Ibi bisigazwa bishobora kuba inkomoko y’ubwandu bw’uduce duto cyangwa imyuka isohoka. Hari ibisigazwa bishobora kandi kugirana ingaruka n’imyuka ikoreshwa mu buryo bw’ikoranabuhanga cyangwa bigasohora imyuka yari yarakubiswe mbere mu gihe cyo gushyushya no gukora plasma.
Ibi bishobora guhindura buhoro buhoro ikirere nyacyo cy’icyumba nubwo uburyo bwo gukora ibintu budahinduka.
Kubera iyo mpamvu, gusukura buri gihe ibyumba, gusimbuza ingabo, kubungabunga ibikoresho, no kugenzura isuku y’ikirere ni bimwe mu bintu by’ingenzi mu gucunga ikirere.
Uburyo bwo gukora PVD buhamye si umusaruro w’uburyo bwo gukora PVD gusa, ahubwo biterwa no kubungabunga ibidukikije bihamye mu cyumba.
8. Ikwirakwizwa rya Gazi rifite akamaro kimwe n'ingano ya Gazi
Ikindi kibazo gifatika ni uko ingano yose ya gazi yinjira mu cyumba idatanga icyizere cy’uko habaho ikirere kimwe.
Imiterere n'aho gazi ijya, agasanduku k'ubwiherero, aho imashini itembera, aho ipompa, valve yo kugosora, n'aho ifata substrate bigena uburyo gazi ikwirakwizwa imbere mu cyumba.
Ikwirakwizwa ribi rya gazi rishobora gutuma habaho itandukaniro mu gice cy’ingufu zikoreshwa mu buryo bufatika cyangwa ubucucike bwa plasma. Ibi bishobora gutuma habaho imiterere itandukanye ya firime cyangwa ubunini butandukanye mu myanya itandukanye kuri substrate.
Ibi ni ingenzi cyane cyane ku buryo bunini bwo gusiga irangi n'ibikoresho byo gukora bifite ubushobozi bwo gutwara ibintu byinshi.
Bityo rero, mu kunoza imashini ikoresha vacuum coating, imiterere y’umuvuduko wa gaze igomba gusuzumwa hamwe n’imiterere ya plasma-source, kuzunguruka kwa substrate, imiterere ya pompe, n’imiterere y’icyumba.
9. Iyo irangi rihindutse mu buryo butunguranye, banza urebe ikirere
Mu musaruro nyawo, ibibazo byo gusiga bikunze kugaragara nk'impinduka zitunguranye mu ibara, ubukana, gufatana, ubunini bwa firime, cyangwa imikorere y'amashanyarazi.
Iyo ibi bibaye, birakenewe guhita uhindura imbaraga zo gushyiramo, imiterere y’ubutaka, cyangwa igihe cyo gushyiramo. Ariko, ibintu bifitanye isano n’ikirere bigomba kubanza kugenzurwa.
Uburyo bwo gukemura ibibazo ni ukugereranya amakuru ajyanye n'umusaruro usanzwe n'imiterere isanzwe y'umusaruro: umuvuduko w'ibanze, igihe cyo kugabanya imashini, umuvuduko w'akazi, umuvuduko w'imikorere n'umwuka, umuvuduko w'umwuka ukoreshwa, aho amashanyarazi ashyirwa, voltage/umuvuduko usohoka, ubushyuhe bw'ubutaka, n'igipimo cyo gushyiramo.
