Emkhakheni wobuchwepheshe obuphezulu bokukhiqiza i-semiconductor, isinyathelo ngasinye sidinga ukunemba nokuhlanzeka okukhethekile. Izimpawu zenjoloba ezikhethekile, njengezingxenye ezibalulekile eziqinisekisa ukusebenza okuzinzile kwemishini yokukhiqiza nokugcina indawo yokukhiqiza ehlanzekile kakhulu, zinomthelela oqondile ekuvunweni nasekusebenzeni kwemikhiqizo ye-semiconductor. Namuhla, sizocubungula ukuthi izigxivizo zenjoloba ezikhethekile ezifana ne-fluororubber ne-perfluoroelastomer zidlala kanjani indima ebalulekile ekwenziweni kwe-semiconductor.
I. Izidingo Eziqinile Zezindawo Zokukhiqiza I-Semiconductor
Ukukhiqizwa kwe-semiconductor ngokuvamile kwenziwa ezindlini ezihlanzekile, lapho izidingo zokuhlanzeka kwemvelo ziphezulu kakhulu. Ngisho nezinhlayiya ezincane zokungcola zingabangela ama-chip short circuits noma okunye ukungasebenzi kahle. Ngaphezu kwalokho, inqubo yokukhiqiza ibandakanya ukusetshenziswa kwamakhemikhali ahlukahlukene agqwala kakhulu, njengama-photoresists, ama-etching solutions, noketshezi lokuhlanza. Ngaphezu kwalokho, ezinye izinyathelo zenqubo ziba nokuguquguquka okukhulu kwezinga lokushisa nokucindezela. Isibonelo, izinqubo ze-etching kanye ne-ion implantation zikhiqiza amazinga okushisa aphezulu kanye nezingcindezi ngaphakathi kwemishini. Ngaphezu kwalokho, imvula evela ku-seal ingaba nomthelela omkhulu ekwenziweni kwe-semiconductor. Ngisho namanani okulandela umkhondo wemvula angangcolisa izinto zokwakha ze-semiconductor noma izinqubo, kuphazamise ukunemba kwenqubo yokukhiqiza.
II. Izindima Ezibalulekile Zezimpawu Zerabha Ezikhethekile
1. Ukuvimbela Ukungcola Kwezinhlayiya: Izigxivizo zenjoloba ezikhethekile zivimbela ngokuphumelelayo uthuli, ukungcola, nezinye izinhlayiya ezivela endaweni yangaphandle ekungeneni kwezinto zokusebenza, zigcina indawo ehlanzekile. Uma sithatha izigxivizo ze-perfluoroelastomer njengesibonelo, indawo yazo ebushelelezi imelana nokumuncwa kwezinhlayiyana. Ukuguquguquka kwazo okuhle kakhulu kuzivumela ukuthi zilingane ngokuqinile ezingxenyeni zemishini, zakha umgoqo wokuvala othembekile futhi ziqinisekise ukuthi inqubo yokukhiqiza i-semiconductor ayinakungcoliswa yizinhlayiyana.
2. Ukumelana Nokugqwala Kwekhemikhali: Izimpawu ezifana ne-fluorocarbon ne-perfluoroelastomer zinikeza ukumelana okuhle kakhulu nama-reagents amakhemikhali avame ukusetshenziswa ekukhiqizeni i-semiconductor. Izigxivizo ze-Fluorocarbon zimelana nezixazululo ezivamile ezine-asidi ne-alkaline nezincibilikisi eziphilayo, kuyilapho izigxivizo ze-perfluoroelastomer zizinzile ikakhulukazi endaweni yamakhemikhali e-oxidizing kanye negqwala. Isibonelo, ezinqubweni zokufakwa okumanzi, izigxivizo ze-perfluoroelastomer zingamelana nokuthintana isikhathi eside nezixazululo zokunamathisela ezine-acidic kakhulu ngaphandle kokugqwala, ziqinisekise ukuvaleka kanye nokuzinza kwezinto zokusebenza.
3. Ukuzivumelanisa Nokuguquguquka Kwezinga Lokushisa Nokucindezela: Amathuluzi okukhiqiza ama-semiconductor ahlangabezana nokushintshashintsha kwezinga lokushisa nokucindezela okuvamile phakathi nokusebenza. Izigxivizo zenjoloba ezikhethekile zidinga ukumelana okuhle kakhulu nezinga lokushisa eliphezulu neliphansi, kanye nokunwebeka okuhle kakhulu nokumelana nokucindezela. Izigxivizo ze-Fluororubber zigcina ukunwebeka okuhle kakhulu nezici zokuvala ngaphakathi kwebanga elithile lokushisa, zivumelana nokushintshashintsha kwezinga lokushisa phakathi nezigaba zokucubungula ezihlukene. Ngakolunye uhlangothi, ama-Perfluoroelastomer seals awagcini nje ngokumelana namazinga okushisa aphezulu kodwa futhi amelana nokuba nzima noma ama-brittle emazingeni okushisa aphansi, agcine ukusebenza okuthembekile kokuvala nokuqinisekisa ukusebenza okuvamile kwemishini ngaphansi kwezimo ezihlukahlukene zokusebenza eziyinkimbinkimbi.
4. Ukulawula Ingozi Yemvula: Ukulawula imvula ezintini kubalulekile ekukhiqizeni ama-semiconductor. Izigxivizo zenjoloba ezikhethekile ezifana ne-fluoroelastomer ne-perfluoroelastomer zisebenzisa ukwakheka okulungiselelwe kanye nezinqubo zokukhiqiza ukuze kuncishiswe ukusetshenziswa kwezithasiselo ezihlukahlukene, ngaleyo ndlela kuncishiswe amathuba okuna kwemvula yokungcola njengama-molecule amancane nama-ion ensimbi phakathi nenqubo yokukhiqiza. Lezi zici zemvula ephansi ziqinisekisa ukuthi ama-seal awabi umthombo ongaba khona wokungcola, okugcina indawo ehlanzeke kakhulu edingekayo ekwenzeni ama-semiconductor.
III. Izidingo Zokusebenza kanye Nemibandela Yokukhetha Yezimpawu Ezikhethekile Zerabha
1. Izakhiwo Ezihlobene Nenhlanzeko: Ubuhwaba obungaphezulu, ukuntengantenga, nokukhishwa kwezinhlayiyana kuyizinkomba ezibalulekile zezimpawu. Ama-seal anobuhwaba obuphansi ajwayelene kakhulu nokunqwabelana kwezinhlayiyana, kuyilapho ukuntengantenga okuphansi kunciphisa ingcuphe yokukhishwa kwegesi ephilayo emazingeni okushisa asezingeni eliphezulu. Lapho ukhetha izigxivizo, beka phambili imikhiqizo ngokwelashwa okukhethekile kwendawo enikeza ukuguquguquka okuphansi kanye nokukhishwa kwezinhlayiyana. Isibonelo, izigxivizo ze-perfluoroelastomer ezine-plasma zinikeza indawo ebushelelezi futhi zinciphisa ngempumelelo ukuguquguquka. Futhi, naka izici zokukhishwa kophawu bese ukhetha imikhiqizo eye yahlolwa kanzima ukuze uqiniseke ukuthi ayikhiphi kukhishwa okuyingozi ezindaweni zokukhiqiza ama-semiconductor.
2. Ukuhambisana kwamakhemikhali: Khetha into efanele yerabha esekelwe kumakhemikhali athile asebenza ngokusebenza kabusha okuhlangatshezwane nawo ngesikhathi sokukhiqiza i-semiconductor. Izinhlobo ezahlukene ze-fluoroelastomer kanye ne-perfluoroelastomer zinokumelana okuhlukahlukene kumakhemikhali ahlukene. Ngezinqubo ezibandakanya ama-acid oxidizing aqinile, ama-perfluoroelastomer seals ane-oxidizing kakhulu kufanele kukhethwe. Ezinqubweni ezibandakanya izinyibilikisi ezivamile zemvelo, ama-fluoroelastomer seal angase abe inketho engabizi kakhulu.
3. Izici zomzimba: Lezi zihlanganisa ubulukhuni, i-elastic modulus, kanye nesethi yokucindezela. Izigxivizo ezinobunzima obumaphakathi ziqinisekisa uphawu oluhle ngenkathi futhi zenza kube lula ukufakwa nokususwa. I-Elastic modulus nesethi yokuminyanisa ibonisa ukuzinza kokusebenza kwesigxivizo ngaphansi kwengcindezi yesikhathi eside. Ezindaweni ezishisa kakhulu nezinomfutho ophezulu, izigxivizo ezinesethi encane yokucindezela kufanele zikhethwe ukuze kuqinisekiswe ukusebenza kokuvala isikhathi eside, okuzinzile.
IV. Ukuhlaziywa Kwekesi Lokusebenza Okusebenzayo
Umkhiqizi owaziwayo we-semiconductor ubebhekene nokugqwala kanye nokuguga kwezigxivizo zenjoloba ezijwayelekile emshinini wokuqopha emugqeni wakhe wokukhiqiza ama-chip. Lokhu kuholele ekuvuzeni kwangaphakathi, kube nomthelela ekusebenzeni kahle kokukhiqiza kanye nokunciphisa kakhulu ukukhiqizwa kwama-chip ngenxa yokungcoliswa kwezinhlayiyana. Ngaphezu kwalokho, izimpawu ezivamile zakhipha ukungcola okuningi kwezinto eziphilayo ngesikhathi senqubo yezinga lokushisa eliphezulu, kungcolisa impahla ye-semiconductor futhi kubangele ukusebenza komkhiqizo okungazinzile. Ngemva kokuwashintsha ngezigxivizo ze-perfluoroelastomer ezikhiqizwa inkampani yethu, ukuzinza kokusebenza kwemishini kwaba ngcono kakhulu. Ngemuva konyaka wokuqapha okuqhubekayo, izigxivizo azizange zibonise izimpawu zokubola noma ukuguga, ukugcina ingaphakathi elihlanzekile kakhulu, nokwandisa umkhiqizo wama-chip kusuka ku-80% kuya ngaphezu kwama-95%. Lokhu kufinyelelwe ngenxa yokumelana okuhle kakhulu kwamakhemikhali e-perfluoroelastomer seal, izici zemvula ephansi, kanye nezakhiwo ezinhle kakhulu ezibonakalayo, okubangele izinzuzo ezinkulu zezomnotho zenkampani.
Isiphetho: Embonini yokukhiqiza i-semiconductor, elwela ukunemba nokuhlanzeka okwedlulele, izigxivizo zenjoloba ezikhethekile zidlala indima ebalulekile. Izigxivizo zenjoloba ezikhethekile ezifana ne-fluoropolymer ne-perfluoroelastomer, ngokusebenza kwazo okuphezulu, okuhlanganisa ukulawula okuqinile phezu kwemvula, zinikeza ukuvala okuthembekile kwemishini yokukhiqiza i-semiconductor, okusiza imboni ukuthi iqhubekele phambili emazingeni aphezulu ezobuchwepheshe.
