Likarolo tsa granite li sebelisoa haholo ts'ebetsong ea tlhahiso ea liphanele tsa LCD. Likarolo tsena li fana ka mefuta e fapaneng ea thepa e li etsang hore li be ntle bakeng sa tšebeliso mechining e hlahisang liphanele tsa LCD. Li tsebahala ka botsitso ba tsona bo phahameng, ho tsamaisa mocheso hantle, le katoloso e tlase ea mocheso. Motsoako ona oa litšobotsi o li etsa thepa e phethahetseng bakeng sa lits'ebetso tse fapaneng tse kang metrology, tlhahiso ea wafer, le lithography.
E 'ngoe ea libaka tsa bohlokoa tsa ts'ebeliso bakeng sa likarolo tsa granite ke tlhahisong ea lisebelisoa tsa metrology. Lisebelisoa tsena li sebelisetsoa ho lekanya botenya ba liphanele, ho teteana ha libaka, le boholo ba tsona. Granite e fana ka botsitso bo botle, 'me sena se bohlokoa bakeng sa lisebelisoa tsa metrology kaha li hloka ho tsitsa ho hlahisa litekanyo tse nepahetseng. Sena se bohlokoa haholo tlhahisong ea liphanele tsa LCD kaha esita le liphetoho tse nyane botenya kapa boholo li ka ama ts'ebetso ea sehlahisoa sa ho qetela. Ka hona, likarolo tsa granite li sebelisoa tlhahisong ea lisebelisoa tsa metrology ho netefatsa ho nepahala le ho nepahala ho holimo.
Sebaka se seng sa ts'ebeliso bakeng sa likarolo tsa granite ke tlhahisong ea mechini e sebelisetsoang ho etsa li-wafer tsa silicon. Mechini ena e bohlokoa tlhahisong ea liphanele tsa LCD, 'me e hloka ho nepahala le ho tsitsa. Granite e fana ka ho tiea le botsitso bo botle, e leng se etsang hore e be khetho e ntle ea thepa bakeng sa mechini e joalo. Ho feta moo, likarolo tsa granite li hanela ho thothomela haholo, e leng ntlha e 'ngoe ea bohlokoa tlhahisong ea li-wafer tsa silicon.
Mokhoeng oa lithography, likarolo tsa granite li sebelisoa e le motheo oa litafole tsa optical tse bohlokoa ts'ebetsong ena. Litafole tsa optical li hloka ho ba tse tsitsitseng haholo, 'me likarolo tsa granite li fana ka thepa ena, e thusang ho netefatsa ho nepahala ts'ebetsong ea tlhahiso. Ho feta moo, likarolo tsa granite li boetse li sebelisoa tlhahisong ea mechini ea stepper. Mechini ena e sebelisoa ho pepesa filimi ea photoresist holim'a li-wafer tsa silicon ho sebelisoa khanya e feteletseng ea ultraviolet. Katoloso e tlase ea mocheso oa granite e etsa hore e be thepa e loketseng ho boloka ho nepahala ha mechini ena.
Qetellong, dikarolo tsa granite di sebediswa tlhahisong ya mechini ya tlhahlobo, e leng se hlokahalang ho lemoha diphoso dife kapa dife hodima di-wafer tsa silicon. Metjhini ena e sebedisa lesedi le matla ho lemoha diphoso dife kapa dife hodima topography ya wafer. Dikarolo tsa granite di thusa ho netefatsa botsitso ba mochini wa tlhahlobo le ho thibela diphoso dife kapa dife tshebetsong ya tlhahlobo.
Qetellong, libaka tsa ts'ebeliso ea likarolo tsa granite bakeng sa lisebelisoa tse sebelisoang ts'ebetsong ea tlhahiso ea liphanele tsa LCD li ngata ebile lia fapana. Litšobotsi tse ikhethang tsa thepa li etsa hore e be ntle bakeng sa ts'ebeliso ea metrology, tlhahiso ea wafer, lithography le mechini ea tlhahlobo. Tšebeliso ea likarolo tsa granite mechining ena e netefatsa hore ts'ebetso ea tlhahiso e nepahetse ebile e sebetsa hantle, e lebisang tlhahisong ea liphanele tsa LCD tsa boleng bo holimo. Ka hona, bahlahisi ba tlameha ho tsoela pele ho sebelisa likarolo tsa granite lisebelisoa tsa bona ho boloka boemo bo holimo ba boleng lihlahisoa tsa bona.
