I-Granite lilitye elenzeka ngokwemvelo eliye lasetyenziswa ixesha elide kwizixhobo zokulungisa i-wafer.Iyaziwa ngeempawu zayo ezintle zokuba nokwandiswa kwe-thermal ephantsi, ukuqina okuphezulu kunye nokuzinza okulungileyo.Nangona kunjalo, njengazo zonke izixhobo, i-granite inesethi yayo yeziphene ezinokuchaphazela umgangatho wezixhobo zokulungisa i-wafer.
Esinye seziphene ezinkulu zegranite kukuthambekela kokuqhekeka okanye ukuqhekeka.Oku kungenxa yobukho be-microcracks enokuthi yenzeke ngexesha lokubunjwa kwelitye.Ukuba ezi microcracks zingachongwa kwaye ziphathwe ngokufanelekileyo, zinokusasaza kwaye zikhokelela ekungaphumeleli kwezixhobo.Ukuthintela oku kungenzeki, abavelisi bezixhobo zokusebenza kufuneka basebenzise igranite ekumgangatho ophezulu oye waphathwa kwaye wavavanywa ukuqinisekisa ukuba awukho kwi-microcracks.
Esinye isiphene segranite kukuchaphazeleka kwayo kukudleka.Ukuba izixhobo zegranite zidibana neendawo ezinobungozi, zinokuqala ukuthotywa ngokuhamba kwexesha.Oku kunokukhokelela ekubeni isixhobo sonakale okanye singasebenzi kakuhle.Ukuthintela oku, abavelisi kufuneka baqinisekise ukuba i-granite esetyenziswa kwizixhobo zabo iphathwa ngokufanelekileyo kwaye igqunywe ukuze kuthintelwe nayiphi na i-corrosion.
I-Granite ikwathandeka ekujikeni ngokuhamba kwexesha ngenxa yeempawu zayo ze-thermal.Oku kungenxa yokuba i-granite ine-coefficient ephantsi kakhulu yokwandiswa kwe-thermal, okuthetha ukuba ayinwebeki okanye iyancipha kakhulu xa ixhomekeke kutshintsho lobushushu.Nangona kunjalo, nokuba inani elincinci lokwandiswa okanye ukucutha kunokubangela ukungqubana kwesixhobo ngokuhamba kwexesha.Kubalulekile ukuba umenzi wezixhobo azithathele ingqalelo iimpawu ze-thermal zegranite xa equlunqa izixhobo zabo zokuthintela esi siphene ukuba senzeke.
Okokugqibela, ubume be granite bunokukhokelela kwimiba yosulelo.Ukuba i-granite ayivalwanga kakuhle, inokufunxa izinto ezingcolisayo ezinokuchaphazela umgangatho we-wafer.Oku kunokukhokelela ekunciphiseni iindleko kunye nokulahleka kwemveliso.Ukuthintela oku, abavelisi kufuneka batywine ngokufanelekileyo igranite ukuthintela naziphi na izinto ezingcolisayo ukuba zifunxwe.
Ukuqukumbela, i-granite sisixhobo esihle kakhulu sokusetyenziswa kwizixhobo zokusetyenzwa kwe-wafer.Nangona kunjalo, kubalulekile ukuba uqaphele iziphene zayo kwaye uthathe amanyathelo afanelekileyo okuthintela ukuba zingenzeki.Ngokhathalelo olufanelekileyo kunye nokugcinwa kakuhle, izixhobo zegranite zinokuqhubeka nokusebenza iminyaka emininzi, zibonelela ngee-wafers ezikumgangatho ophezulu kwishishini le-semiconductor.
