Esikhathini samanje se-semiconductor miniaturization, lapho izici zilinganiswa ngama-nanometer, ubuqotho besakhiwo semishini yokukhiqiza bubaluleke kakhulu njengomthombo wokukhanya uqobo. Njengoba isidingo somhlaba wonke sama-chip anamandla futhi asebenzisa amandla amaningi sikhuphuka, onjiniyela bahlola kabusha izisekelo ezibonakalayo zempahla yabo yegumbi lokuhlanza. Ingxoxo ivame ukugxila ezintweni ezilodwa, ezingaguquguquki: i-granite emnyama yemvelo. Kodwa yini ngempela eyenza i-isiteji se-granite se-photolithographyukukhetha okuphezulu kune-alloys ethuthukisiwe noma izinhlanganisela zokwenziwa ekuphishekeleni ukunemba kwe-sub-micron?
Inselele eyinhloko ku-lithography ukugcina ukunemba okuphelele kwendawo ngesikhathi sokuskena nokuvezwa ngesivinini esikhulu. Noma yikuphi ukudlidliza okuncane noma ukukhukhuleka kokushisa kungaholela emaphutheni okumboza, kubhubhise ngempumelelo i-silicon wafer futhi kubangele ukulahlekelwa okukhulu kwezezimali. Izakhiwo ze-Granite eziphakeme kanye nokudlidliza okumangalisayo zinikeza indawo ethule, engasebenzi. Ngokungafani nezinsimbi, ezisabela ngokubikezela kodwa ngokuphawulekayo ekushintsheni kwezinga lokushisa, i-coefficient yokukhulisa ukushisa ephansi ye-granite iqinisekisa ukuthi isigaba sihlala sizinzile ngokwesilinganiso kulo lonke umjikelezo wokukhiqiza. Lokhu kuzinza kuyisisekelo sangempela lapho yonke imboni ye-semiconductor yakhelwe khona.
Ukusuka esikalini se-nanometer kuya ezweni elinomthamo omkhulu wokukhiqizwa kwebhodi lesifunda eliphrintiwe, izidingo zokuzinza kwemishini zihlala ziqinile ngokulinganayo.isisekelo segranite somshini wokubhoboza we-PCBkumele imelane nokucindezeleka okuqhubekayo, okuvame kakhulu kwemishini kanye nokusheshisa okusheshayo. Ukubhoboza kwe-PCB yesimanje kuhilela ama-spindle ajikeleza kumakhulu ezinkulungwane ze-RPM, ehamba ngesivinini esimangalisayo endizeni ye-XY. Ngaphandle kwesisekelo esikhulu nesiqinile sokumunca la mandla e-kinetic, ukunemba kwemigodi yokubhoboza kungakhukhuleka, okuholela kuma-vias angalingani kahle kanye nokwehluleka kukagesi kumkhiqizo wokugcina. Ngokusebenzisa izisekelo ze-granite zekhwalithi ephezulu, abakhiqizi bangafinyelela ukukhishwa okuphezulu ngaphandle kokulahlekelwa isikhathi eside sokwakheka komshini.
Imininingwane yobuchwepheshe ivame ukuchaza umngcele phakathi kwengxenye ejwayelekile nesisombululo esisebenza kahle kakhulu. Enye yezilinganiso ezibaluleke kakhulu eziceliwe ngabalawuli bekhwalithi baseYurophu naseMelika ukuqeda kobuso.isisekelo segranite esinobulukhuni bomphezulu Ra < 0.8μmakuyona nje impumelelo yobuhle; kuyisidingo esisebenzayo sokulawula ukunyakaza okuthuthukisiwe. Ubuso obunjalo obubushelelezi buvumela ukuhlanganiswa okungenamthungo kwezinhlelo zokuthwala umoya, ezitholakala yonke indawo ezigabeni eziphezulu. Lapho ifilimu yomoya phakathi kwesiteji nesisekelo ingama-micron ambalwa kuphela ubukhulu, ngisho nokuvela okuncane kakhulu ebusweni be-granite kungabangela "ukuphahlazeka" okubi kakhulu, okuholela ekungasebenzi kahle okubizayo kanye nomonakalo ohlala njalo wemishini.
I-ZHHIMG Group ichithe amashumi eminyaka ihlaziya amasu okubopha ngesandla adingekayo ukuze kufezwe lokhu kubekezelelana kwe-sub-micron ngokuthembekile. Nakuba ukugaya kwe-CNC kwanamuhla kunikeza i-geometry yokuqala, ukuqeda kokugcina kwe-“Ra < 0.8μm” kuvame ukuba umphumela wobuchwepheshe bomuntu kanye nokulawulwa okuqinile kwemvelo. Izikhungo zethu zokukhiqiza zigcina izinga lokushisa elihlala njalo kanye nomswakama ukuqinisekisa ukuthi itshe liyalinganiswa futhi liqedwe esimweni salo esizinzile kakhulu. Lokhu kuzinikela kobungcweti yingakho i-ZHHIMG isibe ngumlingani okhethwayo wama-OEM omhlaba wonke angenakukwazi ukuyekethisa ekuqondeni okuyisisekelo kwemishini yawo.
Uma sibheka ikusasa, indima ye-granite embonini ye-elekthronikhi isanda kukhula. Njengoba siqhubekela phambili kuma-node enqubo angu-2nm kanye no-1nm, ukubekezelelana kokusicaba kanye nokungaguquguquki kuzoba nolaka nakakhulu. Imboni ayisafuni nje umhlinzeki wezinto ezibonakalayo; ifuna umlingani oqonda ubudlelwano obuyinkimbinkimbi phakathi kwesayensi yezinto ezibonakalayo kanye nomkhiqizo wemishini. Ngokuhlanganisa izinto ezifakiwe ezithuthukisiwe, iziteshi eziyinkimbinkimbi zokuhambisa ikhebula, kanye nobuchwepheshe besibili bokumboza, i-ZHHIMG iguqula i-slab ye-granite ethobekile ibe yipulatifomu yobunjiniyela eyinkimbinkimbi.
Ekuphetheni, ukuthi ngabe ukunemba komlilo okusheshayo kuyadingeka yiniisisekelo segranite somshini wokubhoboza we-PCBnoma ukuzinza kwezinga le-athomu okudingekayo esiteji se-granite se-photolithography, ukukhetha izinto kucacile. Izakhiwo zemvelo ze-granite, uma zithuthukiswa ubunjiniyela obunembile kanye nobunzima bomphezulu i-Ra < 0.8μm, zinikeza indlela kuphela ephumelelayo yezinqubo zokukhiqiza ezidinga kakhulu emhlabeni. Njengoba ubuchwepheshe buthuthuka, i-ZHHIMG isalokhu izibophezele ekucindezeleni imingcele yalokho okungenzeka, iqinisekise ukuthi izisekelo zomhlaba wedijithali zihlala ziqinile njengedwala.
