Ibhedi yegranite yinxalenye ebalulekileyo koomatshini abaninzi bezixhobo ze-semiconductor, isebenza njengomphezulu othe tyaba nozinzileyo wokucubungula i-wafer. Iimpawu zayo ezihlala ixesha elide nezihlala ixesha elide zenza ukuba ibe lukhetho oludumileyo kubavelisi, kodwa ifuna ukulungiswa ukuze ihlale ikwimeko entle.
Okokuqala, kubalulekile ukuqaphela ukuba igranite yinto yendalo ekwaziyo ukumelana nokuguguleka. Ine-density ephezulu kunye ne-porosity ephantsi, nto leyo eyenza ukuba ingachaphazeleki kakhulu kukugqwala kunye nokuguquka. Oku kuthetha ukuba ibhedi yegranite inokuhlala iminyaka emininzi ngaphandle kokufuna ukutshintshwa logama nje igcinwe kakuhle.
Nangona kunjalo, nangona ineempawu zayo zokumelana nobunzima, ibhedi yegranite isenokonakala ngokuhamba kwexesha, ingakumbi ukuba ivezwe kwiikhemikhali eziqatha okanye amaqondo obushushu aphezulu. Ngenxa yesi sizathu, uhlolo nokucoca rhoqo kubalulekile ukuqinisekisa ukuba umphezulu uhlala uthambile kwaye ungenaziphene ezinokuchaphazela ukucutshungulwa kwe-wafer.
Ngokuphathelele ubomi benkonzo, ibhedi yegranite inokuhlala iminyaka emininzi xa igcinwa icocekile. Ixesha elifanelekileyo lokuphila liya kuxhomekeka kwizinto ezahlukeneyo, njengomgangatho wegranite esetyenzisiweyo, inqanaba lokuguguleka kwayo, kunye nobungakanani bolondolozo elufumanayo.
Ngokubanzi, uninzi lwabavelisi bezixhobo ze-semiconductor bacebisa ukutshintsha ibhedi yegranite rhoqo emva kweminyaka emi-5-10 okanye xa iimpawu zokuguguleka zibonakala. Nangona oku kunokubonakala ngathi kuqhelekile ukutshintshwa, kubalulekile ukuqwalasela ukuchaneka okuphezulu kunye nokuchaneka okufunekayo ekucutshungulweni kwe-wafer. Naziphi na iziphene kumphezulu wegranite zinokubangela iimpazamo okanye ukungangqinelani kwimveliso egqityiweyo, okunokuba nefuthe elikhulu kwezemali.
Ukuqukumbela, ibhedi yegranite yinxalenye ebalulekileyo kwiimashini zezixhobo ze-semiconductor ezinokuhlala iminyaka emininzi ngokugcinwa ngokufanelekileyo. Nangona inokufuna ukutshintshwa rhoqo emva kweminyaka emi-5-10, kuyanceda ukutyala imali kwigranite esemgangathweni ophezulu kunye nokugcinwa rhoqo ukuqinisekisa ukusebenza kakuhle kunye nokuchaneka ekucutshungulweni kwe-wafer.
