Lisebelisoa tsa Granite ka har'a lisebelisoa tsa ho sebetsa ka Wafer
Granite ke thepa e sebelisoang haholo indastering ea ho etsa li-wafer ka lebaka la motsoako oa eona o ikhethang oa thepa.Tse latelang ke tse ling tsa ts'ebeliso ea granite lisebelisoa tsa ho lokisa li-wafer:
1. Lisebelisoa tsa Metrology
Granite hangata e sebelisoa ha ho etsoa lisebelisoa tsa metrology, joalo ka mechini e lekanyang e hokahanyang (CMMs) le lisebelisoa tsa ho metha ka mahlo.Lisebelisoa tsena li hloka libaka tse tsitsitseng tse khonang ho hanela ho thothomela le mocheso.Ho satalla ho phahameng le katoloso e tlase ea mocheso oa granite e etsa hore e be thepa e loketseng lits'ebetso tse joalo.
2. Wafer Chucks
Li-wafer chucks li sebelisoa ho tšoara li-wafers nakong ea ts'ebetso ea tlhahiso.Li-chucks tsena li hloka sebaka se bataletseng le se tsitsitseng ho thibela sephaphatha hore se se ke sa khopama kapa se kobeha.Granite e fana ka sebaka se bataletseng se tsitsitseng haholo ebile se hanana le ho loana, se etsa hore e be thepa e ntle haholo bakeng sa li-wafer chucks.
3. Lisebelisoa tsa Mechanical Polishing (CMP).
Lisebelisoa tsa CMP li sebelisoa ho bentša li-wafers nakong ea ts'ebetso ea tlhahiso.Lisebelisoa tsena li hloka sethala se tsitsitseng se ka hanyetsang ho thothomela le mocheso.Ho satalla ho hotle le katoloso e tlase ea mocheso oa granite e etsa hore e be thepa e loketseng lisebelisoa tsa CMP.
