Umbhede we-granite uyingxenye ebalulekile emishinini eminingi yemishini ye-semiconductor, usebenza njengendawo eyisicaba nezinzile yokucubungula i-wafer. Izakhiwo zayo ezihlala isikhathi eside nezihlala isikhathi eside zenza kube ukukhetha okuthandwayo kwabakhiqizi, kodwa kudinga ukulungiswa okuthile ukuze kugcinwe kusesimweni esihle.
Okokuqala, kubalulekile ukuqaphela ukuthi i-granite iyinto yemvelo ekwazi ukumelana nokuguguleka. Ine-density ephezulu kanye ne-porosity ephansi, okwenza ingabi sengozini yokugqwala nokuguqulwa. Lokhu kusho ukuthi umbhede we-granite ungahlala iminyaka eminingi ngaphandle kokudinga ukushintshwa inqobo nje uma unakekelwa kahle.
Kodwa-ke, ngisho noma inezakhiwo zayo eziqinile, umbhede wegranite usengawohloka ngokuhamba kwesikhathi, ikakhulukazi uma ubhekene namakhemikhali aqinile noma amazinga okushisa aphezulu. Ngenxa yalesi sizathu, ukuhlolwa nokuhlanza njalo kubalulekile ukuqinisekisa ukuthi indawo ihlala ibushelelezi futhi ingenazo iziphambeko ezingathinta ukucutshungulwa kwe-wafer.
Ngokuphathelene nokuphila kwenkonzo, umbhede wegranite ungahlala iminyaka eminingi ngokunakekelwa okufanele. Isikhathi esiqondile sokuphila sizoncika ezintweni ezahlukahlukene, njengekhwalithi yegranite esetshenzisiwe, izinga lokuguguleka nokuklebhuka elibhekana nakho, kanye nenani lokunakekelwa elikutholayo.
Ngokuvamile, abakhiqizi abaningi bemishini ye-semiconductor batusa ukushintsha umbhede we-granite njalo eminyakeni emi-5-10 noma lapho izimpawu zokuguguleka nokuqhekeka zibonakala. Nakuba lokhu kungase kubonakale njengokuvama okuphezulu kokushintsha, kubalulekile ukucabangela ukunemba okuphezulu nokunemba okudingekayo ekucutshungulweni kwe-wafer. Noma yikuphi ukukhubazeka ebusweni be-granite kungabangela amaphutha noma ukungahambisani komkhiqizo oqediwe, okungaba nemiphumela ebalulekile yezezimali.
Ekuphetheni, umbhede wegranite uyingxenye ebalulekile emishinini yemishini ye-semiconductor engahlala iminyaka eminingi ngokunakekelwa okufanele. Nakuba kungadinga ukushintshwa njalo eminyakeni emi-5-10, kuyazuzisa ukutshala imali kugranite esezingeni eliphezulu kanye nokugcinwa njalo ukuqinisekisa ukusebenza okuhle kakhulu kanye nokunemba ekucutshungulweni kwe-wafer.
