I-String photoresist kuyinqubo ebalulekile yokwakha amadivaysi amancane kagesi. Kuyinto esiza ukuqinisekisa ukuthi lezi zisetshenziswa zisebenza kahle futhi zakhiwe ngendlela efanele. Ukwazi ulwazi olwengeziwe nemininingwane mayelana nokukhumula i-photoresist kuzovumela inqubo yokukhiqiza ukuthi ithuthukiswe, futhi kungatholwa amadivayisi angcono.
Ukukhumula i-photoresist kuhilela izisebenzi ezisusa ungqimba olukhethekile, olubizwa nge-photoresist, ku-wafer ye-semiconductor ngemva kokuba lubunjiwe. Le Semixlab ukukhishwa kwe-photoresist Isinyathelo sibaluleke kakhulu ngoba sihlanza i-wafer surface futhi sisusa izinsalela. Abakhiqizi bakhumula i-photoresist ukuze baqinisekise izinyathelo ezilandelayo, njengokuqopha noma ukungeza izendlalelo ezilandelayo, zihamba kahle. Futhi lokhu kusiza ukwenza amadivayisi angcono we-semiconductor.
Ukususwa kwe-photoresist ngokuvamile kuzoba nezinyathelo ezimbalwa. Okokuqala, i-wafer ingena emshinini owaziwa ngokuthi i-photoresist stripper. Lo mshini uhlinzeka ngoketshezi olungasusa i-photoresist (D). I-wafer ihlala oketshezini isikhathi esithile ukuze kuqinisekiswe ukuthi i-photoresist isuswe ngokuphelele. Ngemuva kokufakwa, i-wafer igezwa ngamanzi e-DI ukuze kukhishwe noma yiziphi izinhlayiya ezisele. I-Semixlab amelane nokukhumula I-wafer iyasomiswa futhi ilungiselwe izinyathelo ezilandelayo ohlelweni lokukhiqiza lwedivayisi.
Ziningi izindlela ezikhona zokukhumula i-photoresist ezwela ku-photoresist, ngokusho kwe-Semixlab ukukhishwa kwe-photoresist izidingo ezithile zemishini ezokwenziwa. Ezinye izindlela ezivamile amakhemikhali awuketshezi, i-plasma (igesi ekhethekile) namalaser. Kokubili kunama-pluses nama-minuses, futhi ukukhetha kuncike ku-photoresist ethile oyisebenzisayo nokuthi ufuna ukukwenza ngokushesha kangakanani. Abakhiqizi bangazama izindlela ezahlukahlukene ukuze babone ukuthi iyiphi ebafanele kakhulu.
Ukususwa kwe-photoresist kubaluleke kakhulu ekwenzeni amadivaysi e-semiconductor ekhwalithi ephezulu. Ngokukhumula ungqimba lwe-photoresist ngendlela efanele, abakhiqizi bangaqinisekisa ukuthi amaphethini aku-wafer ahlanzekile futhi ahlanzekile. Le Semixlab i-photoresist kuyadingeka ukuze amadivaysi asebenze kahle, njengoba izingcezu ezengeziwe zizoholela ezinkingeni. Ngaphezu kwalokho, ngendlela efanele, abakhiqizi bangasindisa i-wafer emonakalweni, okuvumela ukukhiqizwa kwemishini eminingi emihle.
I-Semixlab i-photoresist ye-liquid okulandelayo ezinye iziphakamiso eziwusizo zokwenza lula ukuhlubula kwe-photoresist okusebenzayo nokunengqondo. Okokuqala, khetha ithuluzi elifanele lomsebenzi. Futhi, kufanelekile ukulandelela ukuthi ukukhumula kuthatha isikhathi esingakanani nokuthi kushisa kangakanani, njengoba zombili lezi zinto zingathinta imiphumela yakho. Imishini yokukhumula kufanele igcinwe ihlanzekile futhi isesimweni esihle ukuze isebenze kahle. Ngokusebenzisa lawa macebiso, umkhiqizi angenza ukukhiqizwa kwawo kube ngcono futhi akhiqize amadivaysi e-semiconductor ekhwalithi ephezulu.
