I-Granite lilitye elivela ngokwendalo eliye lasetyenziswa ixesha elide kwizixhobo zokucubungula i-wafer. Laziwa ngeempawu zalo ezintle zokuba nobushushu obuphantsi, ukuqina okuphezulu kunye nozinzo oluhle. Nangona kunjalo, njengazo zonke izinto, i-granite ineziphene zayo ezinokuchaphazela umgangatho wezixhobo zokucubungula i-wafer.
Esinye seziphene eziphambili zegranite kukuthambekela kwayo ekuqhekekeni okanye ekuqhekekeni. Oku kungenxa yokubakho kwee-microcracks ezinokwenzeka ngexesha lokwenziwa kwelitye. Ukuba ezi microcracks azichongwanga kwaye aziphathwanga kakuhle, zinokusasazeka kwaye zikhokelele ekungasebenzini kwezixhobo. Ukuthintela oku ukuba kungenzeki, abavelisi bezixhobo zokucubungula kufuneka basebenzise igranite esemgangathweni ophezulu elungisiweyo kwaye ivavanyiwe ukuqinisekisa ukuba ayinazo ii-microcracks.
Esinye isiphene segranite kukuba inokuba sengozini yokugqwala. Ukuba izixhobo zegranite zidibana neendawo ezigqwala, zinokuqala ukuwohloka ngokuhamba kwexesha. Oku kunokubangela ukuba izixhobo zonakale okanye zingasebenzi kakuhle. Ukuthintela oku, abavelisi kufuneka baqinisekise ukuba igranite esetyenziswa kwizixhobo zabo iphathwa kakuhle kwaye igqunywe ukuze kuthintelwe ukuba kubekho ukugqwala.
I-granite ikwathanda ukugoba ngokuhamba kwexesha ngenxa yeempawu zayo zobushushu. Oku kungenxa yokuba i-granite inomlinganiselo ophantsi kakhulu wokwandiswa kobushushu, oko kuthetha ukuba ayikhuli okanye ayinciphisi kakhulu xa itshintsha ubushushu. Nangona kunjalo, nokuba incinci kangakanani na inciphiso okanye ukugoba inokubangela ukugoba kwizixhobo ngokuhamba kwexesha. Kubalulekile ukuba umenzi wezixhobo aqwalasele iimpawu zobushushu ze-granite xa eyila izixhobo zakhe ukuthintela ukuba esi siphene singenzeki.
Okokugqibela, ukuba nemingxuma kwegranite kunokubangela iingxaki zongcoliseko. Ukuba igranite ayivalwanga kakuhle, inokufunxa izinto ezingcolisayo ezinokuchaphazela umgangatho we-wafer. Oku kunokukhokelela ekuchitheni ixesha elininzi kunye nokulahleka kwemveliso. Ukuthintela oku, abavelisi kufuneka bayivale ngokufanelekileyo igranite ukuze bathintele ukuba nayiphi na into engcolisayo ingafunxwa.
Ukuqukumbela, i-granite sisixhobo esifanelekileyo sokusetyenziswa kwizixhobo zokucubungula i-wafer. Nangona kunjalo, kubalulekile ukuqaphela iziphene zayo kwaye uthathe amanyathelo okhuseleko afunekayo ukuthintela ukuba zingenzeki. Ngononophelo olufanelekileyo nokugcinwa kakuhle, izixhobo ze-granite zinokuqhubeka zisebenza iminyaka emininzi, zibonelela ngee-wafers ezikumgangatho ophezulu kwishishini le-semiconductor.
