Ukuguquguquka kokuhambisana kwemishini ye-lithography akuvamile ukuziveza njengokwehluleka okukodwa. Kuvela kancane kancane - iphutha elingaphezulu elihamba ngaphandle kwe-spec kumashifti athile, noma ukuphindaphindeka okulungile ekuseni futhi okungabazekayo ntambama. Lapho umkhiqizi wemishini ye-semiconductor esondela kithina ngaleyo ndlela ohlelweni lokuvezwa olusekelwe ku-gantry, umuzwa ohlangothini lwabo kwakuwukubheka ama-optics kanye nama-motor esiteji kuqala. Umuzwa onengqondo - labo ngokuvamile yibo abasolwayo. Kulokhu, isisekelo sesakhiwo ngaphansi kwe-gantry saphenduka saba nomthelela omkhulu kunanoma ubani owayelindele.
Inkinga Yokuqondanisa
Imishini yayisebenzisa uhlaka lwe-gantry yensimbi oluhlanganisiwe ukuthwala ikhanda le-optical kulo lonke imvilophu yokusebenza. Ephepheni, uhlaka luhlangabezane nokubekezelelana kwalo okungaguquki. Nokho, ekukhiqizeni, umenzi wayebona iphutha lokumboza elalihambisana kahle nesikhathi sosuku kanye nokushintshashintsha kwezinga lokushisa lesitolo - iphethini eyayikhomba ekwandiseni ukushisa kunokuba kube iphutha lomshini noma uhlelo lokulawula. I-coefficient yensimbi yokwandisa ukushisa, kuhlanganiswe nokwakhiwa kwe-welded kohlaka, kwakusho ukuthi ububanzi be-gantry ngokwayo babuhamba ngenani elincane kodwa langempela njengoba izinga lokushisa elizungezile lishintsha ngosuku olujwayelekile lokukhiqiza. Kuhlelo lapho ukulungiswa kwe-sub-micron kuyisidingo esiyisisekelo, ama-micron ambalwa okunyakaza kwesakhiwo okungabalwa anele ukususa iphutha lokumboza ngaphandle kwe-spec ngezikhathi ezithile - okuwuhlobo lwenkinga eqhubekayo, okunzima ukuyixilonga edla amasonto amaningi isikhathi sobunjiniyela ngaphambi kokuba noma ubani abuze uhlaka.
Kungani iGranite Yayiyimpendulo Yesakhiwo
Ukufaka esikhundleni se-gantry yensimbi ehlanganisiwe nge-granite equivalent akuyona into efana neyakho — kushintsha ukucabanga komklamo. I-coefficient ephansi ye-granite yokwandisa ukushisa kanye ne-coefficient ephezulu yokudambisa i-damping kusho ukuthi isakhiwo sizosabela kancane futhi singabi nzima kakhulu ekushintsheni okufanayo kwe-ambient. Okufanelekile futhi: i-granite ayinazo izingcindezi zangaphakathi ezisele njengohlaka lwensimbi oluhlanganisiwe, ngakho-ke ayiqhubeki nokukhukhuleka ngokwesilinganiso eminyakeni eminingi yokujikeleza kokushisa ngendlela isakhiwo sensimbi esenziwe ngayo.
Inselele yobunjiniyela kwakungeyona ukukhethwa kwezinto ezibonakalayo kodwa kwakuwukusebenza — ugongolo lwebhuloho elibanzi oluhlanganisa yonke imishini yokusebenza kwakudingeka lusetshenziswe njengomshini omude, onengxenye eyodwa ukuze kugwenywe ukungeniswa kwamalunga azophinde abuyisele i-granite yokungazinzi okwakufanele ixazululwe. Lowo ngumbuzo womthamo womshini kanye nombuzo wezinto zokwakha; akuwona wonke umenzi wegranite ongacubungula ugongolo olude nolunobunzima oludingekayo ukuze lube yisicaba nesikwele esidingekayo ekusethweni okukodwa. Amandla esikhungo sethu omshini wengxenye eyodwaizingxenye ze-graniteubude obufika kumamitha angu-20 kwenze lokhu kwaba lula ukulingana kunokudinga ukuvumelana okuhlukaniswe ngamabhawodi.
Imininingwane Yokusetshenziswa
Ugongolo lwe-gantry lwaqedwa ngezixhumi zokufaka ze-optical zekhasimende ezifakwe ngqo ku-granite, zibambe ukubekezela kokuthamba kanye nokuma okuqondile okuhambisana nesabelomali sokuqondanisa sohlelo lokudalula. Ukuqedwa kwendawo kulandela uchungechunge olufanayo lokulinganisa olusetshenziswe kumathuluzi ethu okubhekisela ku-granite - olulinganiswe nemishini elandelwa amazinga esikhungo se-metrology sikazwelonke - ngakho ukuhlolwa okuzayo kwekhasimende kwakunemibhalo ehambisanayo, kunokuba kudingeke ukuthi kuqinisekiswe kabusha ukuthamba ngaphambi kokufakwa.
Isisindo kwakuyinto yesibili okufanele siyicabangele ngokwethembeka: i-granite inzima kunengxenye yensimbi yesakhiwo efanayo, futhi kudingeka ama-motor esiteji sekhasimende kanye nesakhiwo sokusekela ukuze kuhlangatshezwane nalowo mehluko. Lokhu kuwukushintshana kwangempela kwemiklamo ye-granite gantry, akuyona into okufanele inganakwa - izinzuzo zokushisa nokunciphisa umswakama ziza nesijeziso esikhulu okumele siklanywe ngaso kunokuba singanakwa.
Umphumela
Ngemva kokufakwa, ikhasimende libike ukuthi iphutha lokumboza alisalandelwa ngesikhathi sosuku noma izinga lokushisa elizungezile ngendlela elaliyiyo ngaphambili - ukuhlangana okwakukhombe ekushintsheni kokushisa ekuxilongweni kokuqala kwanyamalala kakhulu. Ukuphindaphinda phakathi kwamashifu kwaba yinto ehambisanayo, okwakubaluleke kakhulu ekusebenzeni kunanoma yiliphi inombolo eyodwa yokunemba okuphezulu, njengoba isivuno sokukhiqiza sincike ekuhambisaneni phakathi kokugijima okugcwele kunokulinganisa okuhle kakhulu.
Lokho Okushiwo Yileli Cala Ngokubanzi
Izinto eziyisisekelo zesakhiwo kulula ukuzikhohlwa ekuxazululeni izinkinga zokuqondanisa ngoba akuvamile ukuthi kube yinto yokuqala okusolwayo - ama-optics, ama-control loops, kanye ne-stage mechanics okusolwa kuqala, futhi ngezinye izikhathi ngendlela efanele. Kodwa uma ukukhukhuleka kuhambisana nokushisa kunephethini yomthwalo noma yokunyakaza, uhlaka ngokwalo lufanelwe ukubhekwa ngaphambi kokuba kusetshenziswe isikhathi esiningi kulungiswa kabusha izinhlelo ezazingakaze zibe yinkinga yangempela. Izakhiwo ze-granite gantry kanye ne-bridge aziyona into exazululekayo, futhi aziyona impendulo efanele kuzo zonke izinhlobo zemishini - kodwa ngezinhlelo zokusebenza lapho ukuzinza kokushisa kunquma ngqo isivuno, kufanelekile ukuzihlola kusenesikhathi enkambisweni yokuxilonga kunokuba zivame ukuba njalo.
