Thepa e sebetsang ea Wafer e sebelisetsoa ho etsa lisebelisoa tsa microelectronics le semiconductor.Mofuta ona oa thepa o na le likarolo tse 'maloa, ho kenyelletsa le likarolo tsa granite.Granite ke lisebelisoa tse fapaneng tse 'nileng tsa sebelisoa ha ho etsoa thepa ea ho lokisa semiconductor ka lebaka la botsitso ba eona ba mochini, ho hanyetsa lik'hemik'hale, le botsitso ba sebopeho.Sengoliloeng sena se tla tšohla melemo le likotsi tsa ho sebelisa likarolo tsa granite lisebelisoa tsa ho lokisa li-wafer.
Melemo:
1. Ho tsitsa ha mechine: Likarolo tsa granite li tsitsitse haholo, haholo-holo mocheso o phahameng.Sena se etsa hore e be tse loketseng bakeng sa ho sebelisoa lisebelisoa tsa ho lokisa li-wafer, tse sebetsang ka mocheso o phahameng.Likarolo tsa granite li ka mamella meroalo e boima, ho thothomela, le ho sisinyeha ha mocheso ntle le deformation, e netefatsang ho nepahala le ho nepahala ho phahameng.
2. Ho hanyetsa lik'hemik'hale: Granite e hanyetsana le lik'hemik'hale tse ngata tse atisang ho sebelisoa ha ho etsoa li-wafer, ho akarelletsa le li-acids, bases, le solvents.Sena se nolofalletsa lisebelisoa tsa ho lokisa li-wafer ho sebetsana le lisebelisoa tse senyang ntle le ho senya likarolo tsa thepa.
3. Botsitso ba tekanyo: Likarolo tsa granite li na le botsitso bo phahameng ba mahlakore, ho bolelang hore li boloka sebōpeho le boholo ba tsona ho sa tsotellehe liphetoho tsa tikoloho tse kang mocheso le mongobo.Sena ke sa bohlokoa bakeng sa lisebelisoa tsa ho lokisa li-wafer, tse tlamehang ho boloka boemo bo phahameng ba ho sebetsa.
4. Coefficient e tlase ea katoloso ea mocheso: Granite e na le coefficient e tlase ea ho atolosoa ha mocheso, ho bolelang hore ha e atolohe kapa ha e fokotsehe haholo ha e pepesehetse ho fapana ha mocheso.Sena se etsa hore e be e loketseng bakeng sa lisebelisoa tsa ho lokisa li-wafer tse pepesehileng mocheso o phahameng.
5. Nako e telele ea bophelo: Granite ke thepa e tšoarellang 'me e ka tšoarella lilemo tse ngata, esita le libakeng tse thata.Sena se fokotsa litšenyehelo tsa ho lokisa thepa le ho e nchafatsa, ho nolofalletsa bahlahisi ho hlahisa liphaephe tsa boleng bo holimo ka litšenyehelo tse tlase.
Mefokolo:
1. Litšenyehelo tse phahameng: Likarolo tsa granite li theko e boima ho feta lisebelisoa tse ling tse sebelisoang lisebelisoa tsa ho lokisa li-wafer, tse kang tšepe kapa aluminium.Litsenyehelo tse phahameng tsa likarolo tsa granite li eketsa litšenyehelo tse akaretsang tsa lisebelisoa tsa ho lokisa li-wafer, e leng ho etsang hore likhoebo tse nyenyane le tse qalang li se fumanehe.
2. Boima bo boima: Granite ke thepa e teteaneng, 'me likarolo tsa eona li boima ho feta lisebelisoa tse ling tse sebelisoang thepa ea ho lokisa li-wafer.Sena se etsa hore lisebelisoa li be ngata le ho feta ho sisinyeha.
3. Ho thata ho lokisa: Likarolo tsa granite li thata ho lokisoa, 'me hangata ho nkeloa sebaka ke eona feela khetho ha e senyehile.Sena se eketsa litšenyehelo tse eketsehileng bakeng sa tlhokomelo 'me se ka lelefatsa nako ea ho fokotsa lisebelisoa.
4. Brittle: Ho sa tsotellehe botsitso ba mochine oa karolo ea granite, e ka 'na ea robeha ha e le tlas'a boima bo feteletseng kapa tšusumetso.E hloka ho tšoaroa ka hloko le kalafo ho qoba tšenyo e ka senyang likarolo tse nepahetseng tsa thepa.
Qetellong, melemo ea ho sebelisa likarolo tsa granite lisebelisoa tsa ho lokisa li-wafer li feta mefokolo.Leha ho na le litšitiso tse ling, botsitso ba mochini, ho hanyetsa lik'hemik'hale, le botsitso bo boholo ba likarolo tsa granite li etsa hore e be thepa ea bohlokoa bakeng sa ho etsa lisebelisoa tsa boleng bo holimo tsa microelectronics le semiconductor.Ka ho tsetela ho likarolo tsa granite, bahlahisi ba ka fihlela katleho e kholoanyane, ho nepahala le ho phela nako e telele lisebelisoa tsa bona tsa ho lokisa li-wafer.
