Mu gusiga irangi ry'ubushyuhe, kugenzura ubushyuhe si ikintu gipimo gusa - ni ishingiro ry'ubwiza bwa firime, gufatana, no gusubiramo. Kuva ku gushyushya kugeza ku gukonjesha, buri cyiciro cy'ubushyuhe bigira ingaruka ku buryo butaziguye ku miterere ya firime, imiterere y'ubuso, n'imikorere y'amatara cyangwa mashini. Imiterere y'ubushyuhe ikozwe neza ituma habaho imiterere ihamye yo gusiga irangi, igipimo gihoraho cyo gushyiramo irangi, n'umusaruro wizewe w'ibicuruzwa.
1. Uruhare rw'ubushyuhe muGusiga irangi ry'umwuka
Mu gihe cyo gushyira umwuka mu kirere (PVD) cyangwa gushyira umwuka mu kirere mu buryo bwa chemical (CVD), ubushyuhe bukora nk'ikintu cy'ingenzi kigira ingaruka ku migendekere ya adatome, imiterere y'urumuri rw'ishusho, n'uburyo ibintu bikura.
Ubushyuhe buri hasi cyane butuma ubuso bukwirakwira nabi, bigatuma imiterere y’inkingi, imyanda, cyangwa utwenge tw’imigozi bihagarara.
Ubushyuhe bukabije, ku rundi ruhande, bushobora gutera ubushyuhe bukabije, guhinduka kw'ubutaka, cyangwa guhinduka kw'icyiciro kidakenewe.
Bityo, kugenzura neza ubushyuhe bituma abahanga mu by’ubushyuhe bashobora kuringaniza ubucucike bwa firime, imbaraga zo gufatana, n’urwego rw’umuvuduko, bigatuma habaho imikorere myiza n’ubwiza bw’ipamba.
2. Intambwe z'ingenzi zo kugenzura ubushyuhe
Uburyo bwose bwo gusiga ubushyuhe mu buryo bwo gusiga ifu burimo gushyushya mbere, gushyushya, gukonjesha, no gukonjesha bigenzurwa.
(1) Gushyushya munsi y'ubutaka
Mbere yo gushyiramo ibintu, substrates zishyushya buhoro buhoro kugeza ku bushyuhe bwagenwe kugira ngo zikuremo imyanda yo hejuru (nk'amazi cyangwa hydrocarbons) kandi zinoze gufatana kwa firime. Iki cyiciro gisaba kugenzura umuvuduko umwe w'ubushyuhe kugira ngo hirindwe impanuka y'ubushyuhe cyangwa kwaguka gukabije.
(2) Imicungire y'ubushyuhe bwo gushyira mu bikorwa
Mu gihe cyo gukora firime, ubushyuhe bugomba kuguma buhamye muri ± 2–3°C uhereye aho ibintu biherereye. Ihindagurika rishobora guhindura inzira y’ikigereranyo cy’atome zishyushye kandi rigahindura stoichiometry ya firime cyangwa optique constants. Muri sisitemu zo gusohora magnetron, imikorere y’ubushyuhe ikoresheje thermocouples cyangwa infrared sensors akenshi ihuzwa n’igenzura rya PID rifunze kugira ngo habeho uburyo buhamye bwo kugenzura.
(3) Gutunganya Imirongo Ikonjesha
Gukonjesha nyuma yo gukonjesha ni ingenzi cyane. Gukonjesha vuba bishobora gutuma firime icika cyangwa igasigara, mu gihe gukonjesha buhoro bifasha kugumana uburimbane no gufatana neza. Gukonjesha bigenzurwa bigabanya ibyago byo kuzura umwuka iyo uvuye mu kirere cyuzuyemo umwuka ujya mu kirere cyuzuyemo umwuka.
3. Ubuhanga bwo gucunga neza ubushyuhe
Kugira ngo habeho igenzura ry’ubushyuhe neza mu gihe cyose cy’ibikorwa, sisitemu zigezweho zihuza ingamba nyinshi zo gushushanya no gukurikirana:
Gushyushya ahantu henshi: Ahantu higenga ho gushyushya hatuma ubushyuhe bukwirakwira kimwe ku bice binini cyangwa bigoye.
Uburyo bwo gusubiza amakuru mu buryo bufatika: Gukurikirana buri gihe hakoreshejwe sensor zirimo gukora bituma habaho guhindura imbaraga z'ubushyuhe.
Kugereranya imirasire n'amashanyarazi: Gushyira icyuma gishyushya neza bigabanya ubushyuhe.
Gutunganya ibikorwa bishingiye ku gushushanya: Uburyo bwo gushushanya ubushyuhe bufasha kumenya igipimo cyiza cyo kuzamuka no kugabanya ibiciro kuri buri resept yo gusiga.
Gupima ibikoresho byihariye: Ibikoresho bitandukanye bya substrate—nk'amapulasitiki, ikirahure, cyangwa ibumba—bikenera uburyo bwo gushyushya bwihariye bitewe n'uburyo busanzwe bwo gutwara ubushyuhe n'uburyo bwo kwaguka.
4. Ingaruka ku bwiza bwa filime n'umusaruro wayo
Uburyo bugezweho bwo gupima ubushyuhe butuma habaho umusaruro mwiza wo gusiga:
Kongera ubushobozi bwo gufatana kwa firime binyuze mu kunoza uburyo bwo gukwirakwiza amashusho.
Kugabanuka k'umuvuduko w'imbere n'ubucucike bw'inenge.
Ishusho imwe y'urumuri cyangwa icyuma mu buryo bunyuranye bw'ijimetero.
Igipimo cyo gushyiramo ibintu gihamye kandi gishobora gusubiramo ibintu byinshi.
Ku bice by'imodoka, iby'ikoranabuhanga, n'iby'ikoranabuhanga, gucunga ubushyuhe buri gihe bishimangira ko irangi ryujuje ibisabwa mu mikorere no mu buryo bugaragara - kuva ku kurebera mu ndorerwamo kugeza ku gukomera kw'irangi.
5. Umwanzuro
Kugenzura ubushyuhe ni inkingi idasobanutse ya buri sisitemu yo gutwikira ibintu mu buryo bw'umwuka. Mu kumenya neza imiterere y'ubushyuhe - aho gushyiraho ubushyuhe gusa - injeniyeri zishobora kugera ku bwiza bwa firime, kugabanya ubusembwa, no kwizera cyane ibikorwa.
Uko uburyo bwo gusiga irangi ry’ibinyabiziga mu buryo bw’umwuka bugenda bukwirakwira mu myanya y’imbere mu modoka, mu bikoresho by’ikoranabuhanga, no mu gupakira ibikoresho bya semiconductor, uburyo bwo kugenzura ubushyuhe bw’imashini buzakomeza kugaragaza umupaka uri hagati y’irangi risanzwe n’ifilimi nto zakozwe neza.
