Ibyuma by'ubwubatsi byizewe kuri sisitemu yo gucunga ubushyuhe bwa batiri za EV

Mu rwego rwo hejuru rw’inganda zikora ibikoresho bya semiconductor, ubusugire bw’ibice byo gufunga si ikibazo cy’ikoranabuhanga gusa—ni ikintu cy’ingenzi kigena umusaruro n’ubudahinduka bw’imikorere. Mu byumba byo gushushanya plasma no mu bigo byo gusukura intebe, ibikoresho bya elastomeric bihura n’uruvange rubi rw’ibinyabutabire birwanya imihindagurikire y’ikirere, plasma zikoresha ingufu nyinshi, n’ubwikorezi bukabije bw’ubushyuhe. Iyi nyandiko itanga uburyo bwo guhitamo ibisubizo byo gufunga perfluoroelastomer (FFKM) bitazana amazi menshi cyangwa imyuka myinshi cyane muri ibi bihe bibi.

1. Ibidukikije byo gushushanya imiterere ya semiconductor: Ishusho y'ibintu bitatu bidasanzwe

Uburyo bwo gukata, byaba byumye (plasma) cyangwa ibitose (imiti), butanga imbogamizi zidasanzwe zituma ibikoresho bisanzwe birenga imipaka yabyo.

Ibikoresho by’ubutabire bikaze: Ibikoresho nka aside hydrofluoric (HF), aside nitrique, imyuka ishingiye kuri chlorine (Cl₂, BCl₃), na plasma ishingiye kuri fluorine (CF₄, SF₆) byibasira cyane imiyoboro ya polymer. Ibikoresho bisanzwe bya fluoroelastomer (FKM) bishobora kubyimba cyane, kwangirika, cyangwa kwangirika vuba kwa shimi muri ibi bidukikije.

Kugaragara mu maraso hakoreshejwe ingufu nyinshi: Mu bikoresho byumye, utuzu dupfundikiye duterwa n’ubwoko bwa ionized na UV rays. Ibi bituma ubuso bucika, hagacika uduce duto, ndetse hagatera kwandura uduce duto, ibyo bikaba bigira ingaruka ku kutagaragara neza kw’utubuto.

Ibisabwa mu gusohora umwuka mu buryo bukomeye no gusukura: Uburyo bwo gutunganya ibintu bugezweho bukora ku rugero rwo hejuru rw’umwuka mu kirere (≤10⁻⁶ mbar). Imyuka iyo ari yo yose iva mu byuma bifunga—isohoka ry’imyuka yinjijwe cyangwa ibintu bibora—ishobora kwanduza ikirere cy’icyumba, igahungabanya imikorere ya plasma, kandi ikazana imyanda ya karubone.

2. Impamvu FFKM ari yo mahitamo adakuka yo gushushanya

Perfluoroelastome zigaragaza imikorere myiza yo gufunga muri izi porogaramu. Bitandukanye na FKM, igumana hydrogen runaka mu mugongo wayo, FFKM ifite imiterere ya molekile yuzuye fluorine. Iri tandukaniro rikomeye ritanga ubukana bwa shimi bugera hafi kuri bose, kimwe na PTFE, ariko bufite ubushobozi bwo gufunga bukenewe kugira ngo ifunga ribe ryiza.

Ubushobozi bw'ibikoresho bwo kwihanganira ubushyuhe buhoraho kugeza kuri 300–325°C ndetse no gukora ingendo z'igihe gito cyane bituma biba byiza cyane ku bikoresho byo gushushanya, akenshi bikorerwa mu buryo bukomeye mu gihe cyo gutwika kugira ngo bikureho imyanda.

3. Kugera ku gutakaza amazi mu bidukikije birimo aside ikomeye na plasma

Gusohoka kw'ibikoresho bya semiconductor si ko buri gihe biba ari ukudomoka kugaragara; bishobora kugaragara nk'ihindagurika ry'imikorere cyangwa kwanduzwa n'ibindi. FFKM ibikemura binyuze mu miterere n'imiterere y'ibikoresho byabyo.

Ubudakora neza bwa shimi: Imigozi ya karuboni-fluorine muri FFKM iri mu ikomeye cyane muri shimi y’ibinyabuzima. Uku guhagarara neza kw’ibintu bibuza ibintu gukorana na aside zikomeye na oxidizer, bigatuma bigumana ubuhanga bwo gufunga no gukanda mu gihe cy’amasaha ibihumbi.

Ubudahangarwa bwa Plasma: Ingano za FFKM zikora neza cyane zakozwe mu buryo bwihariye kugira ngo zirwanye isuri munsi ya plasma zishingiye kuri ogisijeni na fluorine. Iyi miterere "idafatana" igabanya ikorwa ry'ibice biyobora amazi ku nkuta z'icyumba kandi ikarinda ko ikizingo kiba isoko y'inzira ihindagurika.

Gukomera ku bushyuhe: Inzira zo gukata akenshi zisaba ubwihindurize bwihuse bw'ubushyuhe. FFKM igumana uburyo bwo gukanda buto (akenshi <20–30% nyuma yo gukubitwa igihe kirekire), bigatuma agapfundikizo gakomeza gukoresha imbaraga zihagije ku ngirangingo ndetse no nyuma y'ubwihindurize bw'ubushyuhe bukabije, bityo bikarinda amazi kuva mu bushyuhe bwinshi.

4. Ingorane zo Gukoresha Imyuka Micye n'Inzira FFKM Itanga

Mu bidukikije birimo umwuka mwinshi, gusohora imyuka ni uburyo bw'ibanze bwo gutakaza ubushobozi bwo gukora ibintu butuma ibintu bidahinduka. Ubwoko bw'imyuka ishobora kongera gushyirwa ku buso bwa wafer, bigatuma habaho gushwanyagurika cyangwa guhindura ingano z'ingenzi.

Ubuziranenge bw'ibikoresho: Ibinyabutabire bya FFKM byo mu rwego rwa semiconductor bikorwa bifite ingano nto cyane ya iyoni mu byuma (akenshi biri munsi ya 10 ppm) kandi bigakorerwa ahantu hasukuye kugira ngo bigabanye ingano y'ibinyabuzima ihindagurika kuva mu ntangiriro.

Ubushobozi bwo guteka: Akamaro gakomeye ka FFKM ni ubushobozi bwayo bwo kwihanganira uburyo bwo guteka mu bushyuhe bwinshi (urugero, 150–200°C munsi y’umwuka) mbere yo gutangira gukora. Iyi ntambwe ikuraho ubushuhe n’ibisigazwa by’ibinyabutabire bike, bigatuma habaho igihombo kinini cyane (TML) ndetse n’ibikoresho bishobora guhumeka (CVCM) bikenewe mu bikorwa by’ubwitonzi.

Ubudahangarwa ku gucengera: Inyubako yuzuyemo fluorine ikora nk'uruzitiro rukomeye ku gucengera kwa gazi, ikarinda imyuka yo mu kirere kwinjira mu cyumba no gutunganya imyuka isohoka.

5. Ibipimo ngenderwaho byo guhitamo iby'ingenzi birenga icyiciro cy'ibikoresho

Si ibintu byose bya FFKM bigereranywa. Mu gihe hagenwa ibifunga byo gushushanya, abahanga bagomba gusuzuma ibintu byinshi bifatika.

6. Ingaruka zisanzwe n'imikorere myiza

Kwirinda Gusohora: Mu mikoreshereze ifite ubushobozi bwo gusohora umwuka mwinshi, ikoreshwa ry'ibikoresho birwanya gusohora umwuka (urugero, impeta za PTFE backup) ni byiza kugira ngo hirindwe ko elastomer ishyirwa mu byuho, bishobora gutuma seal inanirwa no gushonga kw'uduce duto.

Gufata no Gushyiraho: Nubwo zikomeye, FFKM seal zishobora gucika intege no gukatwa mu gihe cyo kuzishyiraho iyo zikozwe nabi. Gukoresha ibikoresho byabugenewe byo kuzishyiraho no kwemeza ko impande z'uturemangingo zigororotse (zitari zityaye) ni ingenzi cyane mu kubungabunga ubuziranenge bwa seal.

Gucunga Ubuzima: Guteganya igihe cyo gusimbuza plasma hakoreshejwe gahunda ishingiye ku masaha yo guhurirana (aho gutegereza ko amazi asohoka) ni uburyo bwiza bwo kwirinda igihe cyo kudakora ibikoresho bitateganijwe no gutakaza ibikoresho bya wafer.

7. Ingendo z'ejo hazaza: Intambwe yo kugera ku buziranenge buhanitse

Uko utudomo twa semiconductor tugenda tugera kuri 2nm no hejuru yayo, ubushobozi bwo kwihanganira ubwandu bugera kuri zeru. Inganda zirimo kwerekeza ku miterere ya FFKM "y’igisekuru gikurikira" ifite urwego rwo hasi rw’imyanda ya ioni ndetse n’ibipimo by’uburemere bwa molekile byakozwe mu buryo bwagenewe kugira ngo zikomeze gukumira ibyuka biva mu kirere mu gihe cy’imiterere ikabije ya UV (EUV) lithography na atomic layer etch (ALE).

Umwanzuro

Guhitamo agapapuro gakwiye ka FFKM mu buryo bwo gushushanya ni ikibazo cyo kunoza ibintu byinshi. Intego si uguhitamo gusa ibikoresho birwanya imiti, ahubwo ni uguhitamo imvange n'igishushanyo mbonera bihuza neza n'ibitero bya shimi, ubushyuhe, n'ubuziranenge bw'ibinyabutabire. Mu gushyira imbere amanota meza ya plasma, kubahiriza amategeko akomeye yo gushushanya imiterere y'ibinyabutabire, no gushyira mu bikorwa amabwiriza akomeye yo guteka, abakora ibikoresho n'abahanga mu by'ubukorikori bashobora kugera ku musaruro uhagije kandi udasohora umwuka uhagije ukenewe kugira ngo hakorwe semiconductor nyinshi.

Amabwiriza n'amahame ngenderwaho y'inganda:

ASTM D1418 (Sisitemu Isanzwe yo Gushyira mu Bice Ibikoresho bya Rubber)

SEMI F57-0223 (Ibisobanuro bya sisitemu zo gutunganya, ibikoresho bya semiconductor)
