IGranite yenye yezona zinto ziluncedo kwimveliso ye-semiconductor. Ipropathi yayo eyahlukileyo yenza ukuba ibe lukhetho oluhle lwezicelo ezahlukeneyo. Izinto zeGranite zisetyenziswa kwiimveliso ze-semiconductor zokwenza izinto ngenxa yokuqina, uzinzo, kunye nokuchaneka. Kweli nqaku, siza kuthetha ngeendawo ezinezicelo zamacandelo eGranite kwiimveliso ze-semiconductora yokwenziwa kwenkqubo.
Enye yezicelo eziphambili zezinto ezinobuchule kwimveliso ye-semicondcucy ikwindlela yokuqhubela kwelanga. Ukulungiswa kwelanga kubandakanya inani lamanyathelo ahlukeneyo, kubandakanya nokucoca kunye ne-etching. Izinto zeGranite zisetyenziswa kwezi nkqubo ngenxa yokungaxhathisi. Bakwiflethi emangalisayo ebangela ukuba bafumaneke kusetyenziso lwe-wafes njengoko bebonelela ngomphezulu ozinzileyo ukuze baphumle.
Ukongeza kulungiso lwe-wafer, izinto ze-grancite nazo zikwasetyenziswa kwiLithography. I-Lithography ibandakanya ukuqhuba ipatheni kwi-wafer isebenzisa ukuvezwa kokukhanya. Izinto zeGranite zisetyenziswa kule nkqubo ngenxa yozinzo lwazo kunye nokuchaneka. Banika isiseko esihle kakhulu kwi-wafer kwaye banceda ukuqinisekisa ukuba iphethini ibhujiswa ngokupheleleyo kwi-wafer.
Olunye ukusetyenziswa kwezinto ezinobuchule kwimveliso ye-semicondcuctoration ikwi-metrology. I-Metrology ibandakanya ukulinganisa kweeparameter ezahlukeneyo ezinjengobukhulu kunye nolungelelwaniso. Izinto zeGranite zisetyenziswa kwi-metrology ngenxa yokuchaneka kwabo. Bazinza ngendlela emangalisekileyo ekuncedayo ukuqinisekisa ukuba imilinganiselo ethathiweyo ichanekile kwaye ithembekile.
Izinto zeGranite zikwasetyenziswa kwiinkqubo ze-vacuum. Iinkqubo ze-vacuum zisetyenziswa kwimveliso ye-semiconductor ukudala imeko elawulwayo yeenkqubo ezahlukeneyo. Izinto zeGranite zisetyenziswa kwezi nkqubo ngenxa yokugcina ingqibelelo. Baye baqinisa kakhulu ukuba zenza ukuba balungele ukusetyenziswa kwezicelo ze-vacuum.
Okokugqibela, izinto ezihlekisayo zikwasetyenziswa kwizixhobo ezinje ngeenkqubo zokuhlola kunye neenkqubo zokuvavanya. Ezi nkqubo zisetyenziselwa ukukhangela umgangatho we-wafter kwaye uqinisekise ukuba bayayifezekisa imigangatho efunekayo. Izinto zeGranite zisetyenziswa kwezi nkqubo ngenxa yozinzo lwazo kunye nokuchaneka. Banika isiseko esihle sokuzinza kwi-wafer enceda ekuqinisekiseni ukuba uhlolo luchanekile.
Ukuqukumbela, izinto zegrantite zibalulekile kwiimveliso ze-semicondcuctory zokwenza i-semiconductore. Bahlala bonwabile, bazinza, kwaye bachanekile ezibenza balungele ukusetyenziswa kwizicelo ezahlukeneyo. Ezi zicelo zibandakanya ukuqhutywa kwe-wafere, i-lichography, i-Metrology, iinkqubo ze-vacuum, kunye nezixhobo ezinje ngeenkqubo zokuhlola kunye neenkqubo zokuvavanya. Ukusetyenziswa kwezinto zeGrancite akuqinisekisi kuphela ukuba umgangatho wemveliso yokugqibela iphezulu kodwa iqinisekisa ukuba inkqubo yokuphuhlisa isebenza ngokufanelekileyo nangokungathembeki.
