Izixhobo zokucubungula i-wafer ziyinxalenye ebalulekileyo yenkqubo yokuvelisa i-semiconductor. Ezi matshini zenziwe ngamacandelo ahlukeneyo, kuquka amacandelo e-granite. I-granite yinto efanelekileyo kwezi zinto ngenxa yokuzinza kwayo okuhle kunye nokuqina kwayo. Nangona kunjalo, njengayo nayiphi na enye into, amacandelo e-granite anokuba neziphene ezinokuchaphazela ukusebenza kunye nokusebenza kakuhle kwezixhobo zokucubungula i-wafer. Kweli nqaku, siza kuxoxa ngezinye zeziphene eziqhelekileyo zamacandelo e-granite kwizixhobo zokucubungula i-wafer.
1. Iintanda:
Esinye seziphene eziqhelekileyo kwizixhobo zegranite kukuqhekeka. Ezi mingxunya zinokubangelwa zizinto ezahlukeneyo, kubandakanya ukutshintsha kobushushu obugqithisileyo, uxinzelelo loomatshini, ukuphathwa okungafanelekanga, kunye nokugcinwa okunganelanga. Ukuqhekeka kunokuphazamisa ukuqina kwesakhiwo sezixhobo zegranite, okubangela ukuba zibe sesichengeni sokusilela. Ngaphezu koko, ukuqhekeka kunokusebenza njengeendawo ezinokubangela uxinzelelo, okukhokelela kumonakalo ongakumbi.
2. Ukutshiza:
Esinye isiphene esinokwenzeka kwizixhobo zegranite kukuqhekeka. Ukuqhekeka kunokubangelwa ziziganeko ezahlukeneyo ezifana nokungqubana ngengozi, ukuphathwa ngendlela engafanelekanga, okanye ukukrazuka. Izixhobo zegranite eziqhekekileyo zinokuba nomphezulu orhabaxa kunye nemiphetho engalinganiyo enokonakalisa ii-wafers ngexesha lenkqubo yokwenziwa. Ngaphezu koko, ukuqhekeka kunokuphazamisa ukuchaneka kobukhulu becandelo, okukhokelela ekungasebenzi kakuhle kwezixhobo kunye nexesha lokungasebenzi kwemveliso.
3. Ukuguga nokukrazula:
Ukusetyenziswa rhoqo kunye nokuvezwa rhoqo kwizinto ezirhabaxa kunokubangela ukuguguleka kwezinto zegranite. Ngokuhamba kwexesha, ukuguguleka kunokubangela ukwehla kokusebenza kunye nokusebenza kakuhle kwezixhobo zokucubungula iiwafer. Ukongeza, kunokubangela ukunyuka kweendleko zokulungisa kunye neendleko zokutshintsha.
4. Ukungalingani:
Izinto zegranite, ezifana neetafile zokucubungula iiwafer kunye neechucks, kufuneka zilungelelaniswe ngokuchanekileyo ukuze kugcinwe ukuchaneka kunye nokuhambelana okufunekayo kwinkqubo yokuvelisa. Nangona kunjalo, ukungalingani kunokwenzeka ngenxa yezizathu ezahlukeneyo, ezifana nokufakelwa okungafanelekanga, ukuvezwa kukungcangcazela, okanye umonakalo wecandelo. Ukungalingani kunokukhokelela ekungachanekini ekwenziweni kweewafers, okunokubangela iimveliso ezingasebenzi kakuhle.
5. Ukugqwala:
I-granite yinto engasebenziyo enganyangekiyo kwiikhemikhali ezininzi kunye nezinyibilikisi. Nangona kunjalo, ukuvezwa ixesha elide kwiikhemikhali ezirhabaxa, ezinje ngee-asidi okanye ii-alkali, kunokukhokelela ekungcoleni kwezinto ze-granite. Ukungcola kunokubangela ukuqhekeka komphezulu, ukutshintsha kombala, okanye ukulahleka kokuchaneka kobukhulu.
Isiphelo:
Izinto zegranite zibalulekile ekuzinzeni nasekuthembekeni kwezixhobo zokucubungula iiwafer. Nangona kunjalo, iziphene ezifana nokuqhekeka, ukuqhekeka, ukuguguleka, ukungalungelelani kakuhle, kunye nokugqwala kunokuphazamisa ukusebenza nokusebenza kakuhle kwezi zinto. Ukugcinwa ngokufanelekileyo, ukuphathwa ngokufanelekileyo, kunye nokuhlolwa rhoqo kunokunceda ukuthintela nokunciphisa impembelelo yezi ziphene. Ngokujonga ezi ziphene ngokufanelekileyo, sinokuqinisekisa ukusebenza okuqhubekayo kwezi zinto zibalulekileyo kwaye sigcine umgangatho kunye nokuchaneka kwezixhobo zokucubungula iiwafer.
