Lefapheng la theknoloji e phahameng ea tlhahiso ea semiconductor, mohato o mong le o mong o hloka ho nepahala le bohloeki bo ikhethang. Litiiso tse khethehileng tsa rabara, e le likarolo tsa bohlokoa tse netefatsang ts'ebetso e tsitsitseng ea lisebelisoa tsa tlhahiso le ho boloka tikoloho ea tlhahiso e hloekileng haholo, e na le tšusumetso e tobileng ho chai le ts'ebetsong ea lihlahisoa tsa semiconductor. Kajeno, re tla shebisisa hore na litiiso tse khethehileng tsa rabara tse kang fluororubber le perfluoroelastomer li bapala karolo ea bohlokoa hakae tlhahisong ea li-semiconductor.
I. Litlhoko tse Matla tsa Tikoloho ea Tlhahiso ea Semiconductor
Hangata tlhahiso ea semiconductor e etsoa ka likamoreng tse hloekileng, moo litlhoko tsa bohloeki ba tikoloho li leng holimo haholo. Le likaroloana tse nyane tsa litšila li ka baka li-circuits tse khutšoane tsa chip kapa liphoso tse ling tsa ts'ebetso. Ho feta moo, ts'ebetso ea tlhahiso e kenyelletsa tšebeliso ea mefuta e fapaneng ea lik'hemik'hale tse senyang haholo, tse kang photoresists, etching solutions, le maro a hloekisang. Ho feta moo, mehato e meng ea ts'ebetso e ba le liphetoho tse kholo tsa mocheso le khatello. Ka mohlala, mekhoa ea ho kenya etching le ion e hlahisa mocheso o phahameng le likhatello ka har'a thepa. Ho feta moo, lipula tse tsoang ho litiiso li ka ba le phello e tebileng tlhahisong ea li-semiconductor. Esita le ho sala morao palo ea precipitates e ka silafatsa lisebelisoa kapa mekhoa ea semiconductor, e sitisa ho nepahala ha mokhoa oa tlhahiso.
II. Likarolo tsa Bohlokoa tsa Litiiso tse Khethehileng tsa Rabara
1. Ho Thibela Tšilafalo ea Karolo: Litiiso tse khethehileng tsa rabara li thibela ka katleho lerōle, litšila le likaroloana tse ling tse tsoang tikolohong e ka ntle ho kena thepa, ho boloka tikoloho e hloekileng. Ho nka mohlala oa liqibi tsa perfluoroelastomer, bokaholimo ba tsona bo boreleli bo hanana le ho monya ha likaroloana. Ho feto-fetoha ha tsona ho babatsehang ho li lumella ho lumellana ka thata le likarolo tsa lisebelisoa, ho etsa mokoallo o ka tšeptjoang oa ho tiisa le ho netefatsa hore mokhoa oa ho etsa semiconductor ha o na tšoaetso ea likaroloana.
2. Ho Hanela ho Corrosion ea Lik'hemik'hale: Litiiso tse kang fluorocarbon le perfluoroelastomer li fana ka khanyetso e babatsehang ho li-reagents tsa lik'hemik'hale tse atisang ho sebelisoa ha ho etsoa semiconductor. Litiiso tsa Fluorocarbon li hanana le litharollo tse tloaelehileng tsa asiti le alkaline le lihlapolli tsa lintho tse phelang, ha litiiso tsa perfluoroelastomer li tsitsitse haholo tikolohong ea lik'hemik'hale tse nang le oxidizing le tse senyang. Mohlala, lits'ebetsong tsa etching tse metsi, litiiso tsa perfluoroelastomer li ka mamella ho kopana nako e telele le litharollo tse nang le asiti e ngata ntle le kutu, ho netefatsa ho tiisoa le botsitso ba lisebelisoa.
3. Ho Ikamahanya le Phetoho ea Mocheso le Khatello: Thepa ea tlhahiso ea semiconductor e ba le ho fetoha ha mocheso khafetsa le khatello nakong ea ts'ebetso. Litiiso tse khethehileng tsa rabara li hloka ho hanyetsa mocheso o phahameng le o tlaase, hammoho le elasticity e babatsehang le ho hanyetsa khatello. Litiiso tsa Fluororubber li boloka elasticity le thepa ea ho tiisa ka har'a mefuta e itseng ea mocheso, e ikamahanya le ho fetoha ha mocheso nakong ea mekhahlelo e fapaneng ea ts'ebetso. Litiiso tsa Perfluoroelastomer, ka lehlakoreng le leng, ha li mamelle mocheso o phahameng feela empa li boetse li hanela ho ba thata kapa ho senyeha ha mocheso o tlase, ho boloka ts'ebetso e tšepahalang ea ho tiisa le ho netefatsa ts'ebetso e tloaelehileng ea lisebelisoa tlasa maemo a fapaneng a rarahaneng a ts'ebetso.
4. Ho Laola Kotsi ea Pula: Ho laola pula ho tloha ho litiiso ho bohlokoa haholo tlhahisong ea li-semiconductor. Litiiso tse khethehileng tsa rabara tse kang fluoroelastomer le perfluoroelastomer li sebelisa mekhoa e ntlafalitsoeng le lits'ebetso tsa tlhahiso ho fokotsa ts'ebeliso ea li-additives tse fapaneng, ka hona li fokotsa monyetla oa ho putlama ha litšila joalo ka limolek'hule tse nyane tsa organic le li-ion tsa tšepe nakong ea ts'ebetso ea tlhahiso. Litšobotsi tsena tsa pula e tlase li netefatsa hore litiiso ha li fetohe mohloli oa tšilafalo, ho boloka tikoloho e hloekile haholo e hlokahalang bakeng sa tlhahiso ea li-semiconductor.
III. Litlhoko tsa Ts'ebetso le Mekhoa ea Khetho bakeng sa Litiiso tse khethehileng tsa Rubber
1. Lintho Tse Amanang le Bohloeki: Ho ba makukuno ha holim'a metsi, ho feto-fetoha ha maemo, le ho lokolloa ha likaroloana ke matšoao a ka sehloohong a liqibi. Litiiso tse nang le mahoashe a tlase ha li na monyetla oa ho bokella likaroloana, athe ho fetoha ha maemo ho fokotsa kotsi ea ho tsoa ha likhase tse tsoang ho litiiso libakeng tse nang le mocheso o phahameng. Ha u khetha litiiso, beha pele lihlahisoa tse nang le liphekolo tse khethehileng tsa holim'a metsi tse fanang ka phetoho e tlase le tlhahiso ea likaroloana. Ka mohlala, litiiso tsa perfluoroelastomer tse entsoeng ka plasma li fana ka sebaka se boreleli 'me ka katleho li fokotsa ho fetoha ha maemo. Hape, ela hloko thepa ea tokollo ea tiiso 'me u khethe lihlahisoa tse entseng tlhahlobo e matla ea tokollo ho netefatsa hore ha li ntše mesi e kotsi libakeng tsa tlhahiso ea li-semiconductor.
2. Tšebelisano ea lik'hemik'hale: Khetha thepa e nepahetseng ea rabara e thehiloeng ho li-reagents tse khethehileng tsa lik'hemik'hale tse kopaneng nakong ea tlhahiso ea semiconductor. Mefuta e fapaneng ea fluoroelastomer le perfluoroelastomer e na le khanyetso e fapaneng ea lik'hemik'hale tse fapaneng. Bakeng sa lits'ebetso tse kenyelletsang li-acid tse matla tsa oxidizing, litiiso tsa perfluoroelastomer tse nang le oxidizing haholo li tlameha ho khethoa. Bakeng sa lits'ebetso tse kenyelletsang lihlapolli tse akaretsang tsa organic, litiiso tsa fluoroelastomer e ka ba khetho e ntle haholo.
3. Lintho tsa 'mele: Tsena li kenyelletsa ho thatafala, modulus ea elastic, le sete ea ho hatella. Litiiso tse nang le boima bo itekanetseng li tiisa tiiso e ntle ha li ntse li thusa ho kenya le ho tlosoa. Elastic modulus le compression set se bonts'a botsitso ba ts'ebetso ea tiiso tlas'a khatello ea nako e telele. Libakeng tse nang le mocheso o phahameng le o nang le khatello e phahameng, litiiso tse nang le khatello e fokolang ea khatello li lokela ho khethoa ho netefatsa ts'ebetso ea nako e telele, e tsitsitseng ea ho tiisa.
IV. Tlhahlobo e sebetsang ea Nyeoe ea Kopo
Moetsi ea tsebahalang oa semiconductor o ne a na le ho bola khafetsa le botsofali ba litiiso tse tloaelehileng tsa rabara ka har'a lisebelisoa tsa ho kenya mochini oa eona oa ho etsa li-chip. Sena se ile sa lebisa ho lutla ka hare, ho ama ts'ebetso ea tlhahiso le ho fokotsa haholo chai ea chip ka lebaka la tšilafalo ea likaroloana. Ho feta moo, litiiso tse tloaelehileng li ile tsa lokolla litšila tse ngata tsa tlhaho nakong ea mocheso o phahameng oa mocheso, li silafatsa thepa ea semiconductor le ho baka ts'ebetso e sa tsitsang ea sehlahisoa. Kamora ho li nkela sebaka ka litiiso tsa perfluoroelastomer tse entsoeng ke k'hamphani ea rona, botsitso ba ts'ebetso ea lisebelisoa bo ile ba ntlafala haholo. Kamora selemo sa ts'ebetso e tsoelang pele ea ts'ebetso, litiiso li ne li sa bonts'a matšoao a ho bola kapa botsofali, ho boloka bokahare bo hloekile haholo, le ho eketsa chai ea chip ho tloha ho 80% ho ea ho 95%. Sena se fihletsoe ka lebaka la khanyetso e ntle ea lik'hemik'hale ea li-perfluoroelastomer seals, litšoaneleho tsa pula e tlase, le thepa e ntle ea 'mele, e hlahisitseng melemo e meholo ea moruo bakeng sa k'hamphani.
Qetello: Ka indasteri ea tlhahiso ea semiconductor, e hahamallang ho nepahala le bohloeki bo feteletseng, litiiso tse khethehileng tsa rabara li bapala karolo ea bohlokoa. Litiiso tse khethehileng tsa rabara tse kang fluoropolymer le perfluoroelastomer, ka ts'ebetso ea tsona e phahameng, ho kenyelletsa taolo e tiileng holim'a pula, li fana ka tiiso e tšepahalang bakeng sa lisebelisoa tsa tlhahiso ea semiconductor, ho thusa indasteri ho tsoela pele ho ea maemong a phahameng a theknoloji.
