Iziseko zegranite zisetyenziswa kakhulu kwizixhobo ze-semiconductor ngenxa yeempawu zazo eziphezulu zokunciphisa ubushushu, ubushushu kunye nokungcangcazela. Ukukhethwa kwezinto zegranite kunokuchaphazela kakhulu ukusebenza kwezixhobo ze-semiconductor. Kweli nqaku, siza kuhlola indlela izinto zesiseko segranite ezichaphazela ngayo ukusebenza kwezixhobo ze-semiconductor ngendlela eyakhayo.
Okokuqala, i-granite lukhetho oluhle kakhulu lwezinto ezisetyenziswa kwisiseko sezixhobo ze-semiconductor ngenxa yozinzo lwayo oluphezulu lobushushu. Ukwenziwa kwe-semiconductor kubandakanya iinkqubo zobushushu obuphezulu ezifana nokugrumba kwe-plasma, ukufakwa kwe-ion, kunye ne-epitaxy. Ukuguquguquka kobushushu kunokuchaphazela umgangatho kunye nokusebenza kwesixhobo se-semiconductor. Izinto ze-granite zine-coefficient yokwandisa ubushushu ephantsi, nto leyo eyenza ukuba ibe lukhetho olufanelekileyo lokuxhasa izixhobo ze-semiconductor. I-coefficient yokwandisa ubushushu ephantsi iqinisekisa ukuba isiseko sesixhobo siya kuhlala sizinzile nokuba kubushushu obuphezulu, ngaloo ndlela kuqinisekiswa umgangatho kunye nokusebenza kwesixhobo se-semiconductor.
Okwesibini, izinto zegranite zineempawu ezibalaseleyo zokudambisa ukungcangcazela, nto leyo enceda ekuphuculeni ukuchaneka nokuchaneka kwezixhobo ze-semiconductor. Ukwenziwa kwee-semiconductor kubandakanya iinkqubo ezichanekileyo nezinobunono, ezifana ne-lithography, ukulungelelaniswa kwe-wafer, kunye nokudluliselwa kwepateni. Ukungcangcazela okuveliswayo ngexesha lezi nkqubo kunokuchaphazela ukusebenza kwesixhobo se-semiconductor, okukhokelela kwiziphene kunye nokuncipha kwemveliso. Izinto zegranite zifunxa ukungcangcazela kwaye zithomalalise ukuphazamiseka koomatshini, ngaloo ndlela ziqinisekisa ukuchaneka nokuchaneka kwezixhobo ze-semiconductor.
Okwesithathu, izinto zegranite zineempawu zoomatshini eziphezulu, eziqinisekisa ukuqina kunye nokuzinza kwexesha elide kwezixhobo ze-semiconductor. Izixhobo zokwenza i-semiconductor zihlala zigugile ngenxa yokusetyenziswa rhoqo kunye nokuchatshazelwa ziikhemikhali eziqatha kunye neemeko zokusingqongileyo. Izinto zegranite ziqinile, zixinene, kwaye ziyamelana nokufuma, iikhemikhali kunye nokugqwala. Ezi mpawu zenza isiseko segranite sibe yinto eqinileyo nehlala ixesha elide kwizixhobo ze-semiconductor, ukuqinisekisa uzinzo kunye nokuthembeka kwaso ixesha elide.
Ukuqukumbela, izinto ezisetyenziswa kwisiseko segranite zichaphazela kakhulu ukusebenza kwezixhobo ze-semiconductor ngendlela eyakhayo. Amandla egranite okugcina uzinzo lwayo kumaqondo obushushu aphezulu, ukufunxa ukungcangcazela, kunye nokumelana nokuguguleka kwenza ukuba ibe yinto efanelekileyo yokuxhasa nokuzinzisa izixhobo zokwenza i-semiconductor ezintsonkothileyo. Ukusetyenziswa kwesiseko segranite kuqinisekisa umgangatho kunye nokusebenza kwezixhobo ze-semiconductor, okukhokelela ekuphuculweni kwemveliso, isivuno esiphezulu, kunye neendleko ezincitshisiweyo kushishino lwe-semiconductor.
