Emkhakheni wezobuchwepheshe obuphezulu wokukhiqiza ama-semiconductor, isinyathelo ngasinye sidinga ukunemba nokuhlanzeka okumangalisayo. Izivikelo zerabha ezikhethekile, njengezingxenye ezibalulekile eziqinisekisa ukusebenza okuzinzile kwemishini yokukhiqiza futhi zigcina indawo yokukhiqiza ehlanzekile kakhulu, zinomthelela oqondile ekukhiqizeni nasekusebenzeni kwemikhiqizo yama-semiconductor. Namuhla, sizohlola ukuthi izivikelo zerabha ezikhethekile ezifana ne-fluororubber kanye ne-perfluoroelastomer zidlala kanjani indima ebalulekile ekukhiqizeni ama-semiconductor.
I. Izidingo Eziqinile Zezindawo Zokukhiqiza Ama-Semiconductor
Ukukhiqizwa kwe-semiconductor kuvame ukuqhutshwa emakamelweni ahlanzekile, lapho izidingo zokuhlanzeka kwemvelo ziphezulu kakhulu. Ngisho nezinhlayiya ezincane zokungcola zingabangela ama-chip short circuits noma ezinye izinkinga zokusebenza. Ngaphezu kwalokho, inqubo yokukhiqiza ihilela ukusetshenziswa kwamakhemikhali ahlukahlukene abola kakhulu, njenge-photoresists, izixazululo zokuchoboza, kanye noketshezi lokuhlanza. Ngaphezu kwalokho, ezinye izinyathelo zenqubo zithola ukuguquguquka okukhulu kwezinga lokushisa kanye nengcindezi. Isibonelo, izinqubo zokuchoboza kanye nokufakelwa kwama-ion zikhiqiza amazinga okushisa aphezulu kanye nengcindezi ngaphakathi kwemishini. Ngaphezu kwalokho, ama-precipitate avela ezivalweni angaba nomthelela omkhulu ekukhiqizweni kwe-semiconductor. Ngisho namanani amancane ama-precipitate angangcolisa izinto noma izinqubo ze-semiconductor, okuphazamisa ukunemba kwenqubo yokukhiqiza.
II. Izindima Ezibalulekile Zezimbozo Zenjoloba Ezikhethekile
1. Ukuvimbela Ukungcoliswa Kwezinhlayiyana: Izimbozo zerabha ezikhethekile zivimba ngempumelelo uthuli, ukungcola, kanye nezinye izinhlayiya ezivela endaweni yangaphandle ukuthi zingangeni emishinini, zigcine indawo ihlanzekile. Uma sibheka izimbozo ze-perfluoroelastomer njengesibonelo, ubuso bazo obubushelelezi buyamelana nokumuncwa kwezinhlayiyana. Ukuguquguquka kwazo okuhle kakhulu kuzivumela ukuthi zilingane kahle nezingxenye zemishini, zakha isithiyo sokuvala esithembekile futhi ziqinisekise ukuthi inqubo yokukhiqiza i-semiconductor ayinazo izinhlayiyana ezingcolisayo.
2. Ukumelana Nokugqwala Kwamakhemikhali: Izivalo ezifana ne-fluorocarbon kanye ne-perfluoroelastomer zinikeza ukumelana okuhle kakhulu nama-reagent amakhemikhali asetshenziswa kakhulu ekukhiqizeni ama-semiconductor. Izivalo ze-Fluorocarbon ziyamelana nezixazululo ezivamile ze-acidic kanye ne-alkaline kanye nezinyibilikisi eziphilayo, kuyilapho izivalo ze-perfluoroelastomer zizinzile kakhulu ezindaweni zamakhemikhali ezikhipha i-oxidizing kakhulu futhi ezibolayo. Isibonelo, ezinqubweni zokugqwala ezimanzi, izivalo ze-perfluoroelastomer zingamelana nokuxhumana isikhathi eside nezixazululo zokugqwala ezine-acidic kakhulu ngaphandle kokugqwala, okuqinisekisa ukuvalwa nokuqina kwemishini.
3. Ukuzivumelanisa Nokushintshashintsha Kwezinga Lokushisa Nokucindezela: Imishini yokukhiqiza i-semiconductor ibhekana nokushintshashintsha njalo kwezinga lokushisa nokucindezela ngesikhathi sokusebenza. Izivalo zerabha ezikhethekile zidinga ukumelana okuhle kakhulu kwezinga lokushisa eliphezulu neliphansi, kanye nokuqina okuhle kakhulu nokumelana nokucindezela. Izivalo zerabha ze-fluororubber zigcina ukuqina okuhle kakhulu kanye nezakhiwo zokuvala ngaphakathi kwebanga elithile lokushisa, zivumelana nokushintshashintsha kwezinga lokushisa phakathi nezigaba ezahlukene zokucubungula. Izivalo ze-Perfluoroelastomer, ngakolunye uhlangothi, azigcini nje ngokumelana namazinga okushisa aphezulu kodwa futhi ziyamelana nokuba lukhuni noma ziqhekeke emazingeni okushisa aphansi, zigcina ukusebenza kokuvala okuthembekile futhi ziqinisekisa ukusebenza okuvamile kwemishini ngaphansi kwezimo zokusebenza ezahlukahlukene eziyinkimbinkimbi.
4. Ukulawula Ingozi Yemvula: Ukulawula imvula evela ezimpahleni kubalulekile ekukhiqizweni kwe-semiconductor.

Lezi zici zemvula ephansi ziqinisekisa ukuthi izimpahle azibi umthombo ongaba khona wokungcola, zigcine indawo ehlanzekile kakhulu edingekayo ekukhiqizweni kwe-semiconductor.
III. Izidingo Zokusebenza kanye Nezindlela Zokukhetha Izisimbozo Zenjoloba Ezikhethekile
1. Izakhiwo Ezihlobene Nokuhlanzeka: Ubulukhuni bomphezulu, ukuguquguquka, kanye nokukhululwa kwezinhlayiya kuyizinkomba ezibalulekile zezinhlayiya. Izinhlayiya ezinobulukhuni obuphansi bomphezulu azivamile ukuqongelela izinhlayiya, kuyilapho ukuguquguquka okuphansi kunciphisa ingozi yokukhishwa kwegesi yemvelo okuvela ezinhlayiya ezindaweni ezishisa kakhulu. Uma ukhetha izinhlayiya, beka phambili imikhiqizo enokwelashwa okukhethekile komphezulu okunikeza ukuguquguquka okuphansi kanye nokukhishwa kwezinhlayiya. Isibonelo, izinhlayiya ze-perfluoroelastomer eziphathwe nge-plasma zinikeza indawo ebushelelezi futhi zinciphisa ngempumelelo ukuguquguquka. Futhi, naka izakhiwo zokukhishwa kwesinhlayiya bese ukhetha imikhiqizo eye yahlolwa kanzima ukuze kuqinisekiswe ukuthi ayikhiphi ukukhishwa okuyingozi ezindaweni zokukhiqiza ze-semiconductor.
2. Ukuhambisana kwamakhemikhali: Khetha izinto zerabha ezifanele ngokusekelwe kuma-reagents athile amakhemikhali atholakale ngesikhathi sokukhiqizwa kwe-semiconductor. Izinhlobo ezahlukene ze-fluoroelastomer kanye ne-perfluoroelastomer zinokuphikisana okuhlukahlukene kwamakhemikhali ahlukene. Ngezinqubo ezibandakanya ama-acid aqinile okuxilisa, kumele kukhethwe izivalo ze-perfluoroelastomer ezixilisa kakhulu. Ngezinqubo ezibandakanya izinyibilikisi ezijwayelekile zezinto eziphilayo, izivalo ze-fluoroelastomer zingaba inketho engabizi kakhulu.
3. Izakhiwo zomzimba: Lokhu kufaka phakathi ubulukhuni, i-elastic modulus, kanye nesethi yokucindezela. Izivalo ezinobulukhuni obuphakathi ziqinisekisa ukuvala okuhle ngenkathi futhi zenza kube lula ukufakwa nokususwa. I-elastic modulus kanye nesethi yokucindezela zibonisa ukuqina kokusebenza kwesivalo ngaphansi kokucindezeleka kwesikhathi eside. Ezindaweni ezinokushisa okuphezulu kanye nokucindezela okuphezulu, izivalo ezinesethi yokucindezela okuncane kufanele zikhethwe ukuqinisekisa ukusebenza kokuvala okuzinzile kwesikhathi eside.
IV. Ukuhlaziywa Kwecala Lokusebenza Okusebenzayo
Umkhiqizi we-semiconductor owaziwayo wayebhekana nokugqwala njalo kanye nokuguga kwezimpawu zerabha ezivamile emishinini yokuqopha emgqeni wakhe wokukhiqiza ama-chip. Lokhu kwaholela ekuvuza kwangaphakathi, kwathinta ukusebenza kahle kokukhiqiza futhi kwanciphisa kakhulu isivuno sama-chip ngenxa yokungcoliswa kwezinhlayiya. Ngaphezu kwalokho, izimpawu ezivamile zakhipha inani elikhulu lokungcola okungokwemvelo ngesikhathi senqubo yokushisa okuphezulu, zangcolisa izinto ze-semiconductor futhi zabangela ukusebenza komkhiqizo okungazinzile. Ngemva kokuzishintsha ngezimbozo ze-perfluoroelastomer ezenziwe yinkampani yethu, ukuzinza kokusebenza kwemishini kwathuthuka kakhulu. Ngemva konyaka wokuqapha okuqhubekayo kokusebenza, izimpawu azibonisanga zimpawu zokugqwala noma ukuguga, zigcina ingaphakathi lihlanzekile kakhulu, futhi zandisa isivuno sama-chip kusuka ku-80% kuya ngaphezu kuka-95%. Lokhu kufezwe ngenxa yokumelana okuhle kwamakhemikhali kwama-perfluoroelastomer seals, izici zemvula ephansi, kanye nezakhiwo zomzimba ezinhle kakhulu, okwaholela ezinzuzweni ezinkulu zomnotho zenkampani.
Isiphetho: Embonini yokukhiqiza ye-semiconductor, elwela ukunemba okukhulu nokuhlanzeka, izimbobo zerabha ezikhethekile zidlala indima ebalulekile. Izimbobo zerabha ezikhethekile ezifana ne-fluoropolymer kanye ne-perfluoroelastomer, ngokusebenza kwazo okuphezulu, okuhlanganisa nokulawula okuqinile phezu kwemvula, zinikeza ukuvalwa okuthembekile kwemishini yokukhiqiza ye-semiconductor, okusiza imboni ukuthi iqhubekele phambili emazingeni aphezulu obuchwepheshe.
