Izingxenye zegranite zisetshenziswa kabanzi enqubweni yokukhiqiza amaphaneli e-LCD. Lezi zingxenye zinikeza uhla lwezakhiwo ezenza zibe zilungele ukusetshenziswa emishinini ekhiqiza amaphaneli e-LCD. Zaziwa ngokuzinza kwazo okuphezulu, ukuhanjiswa kokushisa okuhle kakhulu, kanye nokwandiswa kokushisa okuphansi. Lokhu kuhlanganiswa kwezici kuzenza zibe yinto efanelekile yezinhlelo zokusebenza ezahlukahlukene ezifana ne-metrology, ukwenziwa kwe-wafer, kanye ne-lithography.
Enye yezindawo ezisetshenziswa kakhulu zezingxenye zegranite ukukhiqizwa kwamathuluzi okukala imitha. Lawa mathuluzi asetshenziselwa ukukala ubukhulu bamaphaneli, ubulukhuni bendawo, kanye nosayizi wawo. Igranite inikeza ukuzinza okuhle kakhulu, futhi lokhu kubalulekile kumathuluzi okukala imitha njengoba kudingeka aqine ukuze akhiqize izilinganiso ezinembile. Lokhu kubaluleke kakhulu ekukhiqizweni kwamaphaneli e-LCD njengoba ngisho nokwehluka okuncane ekujikeni noma usayizi kungathinta ukusebenza komkhiqizo wokugcina. Ngakho-ke, izingxenye zegranite zisetshenziswa ekukhiqizweni kwamathuluzi okukala imitha ukuqinisekisa ukunemba okuphezulu nokunemba.
Enye indawo esetshenziswayo yezingxenye zegranite isekukhiqizweni kwemishini esetshenziselwa ukwakha ama-wafer e-silicon. Le mishini ibalulekile ekukhiqizweni kwamaphaneli e-LCD, futhi kudingeka ibe nembambo futhi iqine. I-Granite inikeza ukuqina nokuqina okuhle kakhulu, okwenza kube ukukhetha okuhle kwezinto zokwakha zemishini enjalo. Ngaphezu kwalokho, izingxenye zegranite zimelana kakhulu nokudlidliza, okungenye into ebalulekile ekukhiqizweni kwama-wafer e-silicon.
Enqubweni ye-lithography, izingxenye ze-granite zisetshenziswa njengesisekelo samatafula optical abalulekile kule nqubo. Amatafula optical kudingeka azinze kakhulu, futhi izingxenye ze-granite zinikeza le mpahla, okusiza ukuqinisekisa ukunemba enqubweni yokukhiqiza. Ngaphezu kwalokho, izingxenye ze-granite zisetshenziswa nasekukhiqizweni kwemishini ye-stepper. Le mishini isetshenziselwa ukuveza ifilimu ye-photoresist kuma-wafer e-silicon kusetshenziswa ukukhanya okukhulu kwe-ultraviolet. Ukwanda okuphansi kokushisa kwe-Granite kwenza kube yinto efanelekile yokugcina ukunemba kwale mishini.
Okokugcina, izingxenye zegranite zisetshenziswa ekukhiqizweni kwemishini yokuhlola, edingekayo ukuthola noma yiziphi iziphambeko kuma-wafer e-silicon. Le mishini isebenzisa ukukhanya okunamandla kakhulu ukuthola noma yiziphi iziphambeko endaweni ye-wafer. Izingxenye zegranite zisiza ukuqinisekisa ukuzinza komshini wokuhlola nokuvimbela noma yimaphi amaphutha enkambisweni yokuhlola.
Ekuphetheni, izindawo zokusetshenziswa kwezingxenye zegranite kumadivayisi asetshenziswa enkambisweni yokukhiqiza amaphaneli e-LCD ziningi futhi ziyahlukahluka. Izici ezihlukile zale nto zenza kube kuhle ukusetshenziswa emishinini ye-metrology, ekwakhiweni kwe-wafer, i-lithography, kanye nemishini yokuhlola. Ukusetshenziswa kwezingxenye zegranite kule mishini kuqinisekisa ukuthi inqubo yokukhiqiza inembile futhi isebenza kahle, okuholela ekukhiqizweni kwamaphaneli e-LCD asezingeni eliphezulu. Ngakho-ke, abakhiqizi kumele baqhubeke nokusebenzisa izingxenye zegranite kumadivayisi abo ukuze balondoloze izinga eliphezulu lekhwalithi emikhiqizweni yabo.
