Ibhedi yegranite yenye yezona zinto zixhaphakileyo ezisetyenziswa ekwenzeni izixhobo ze-semiconductor ezichanekileyo kakhulu. Lilitye elenziwa kukucotha nokuqina kwe-magma nzulu ngaphakathi koqweqwe lomhlaba. Uphawu oluphambili lwegranite kukuba yinto eqinileyo, exineneyo, nehlala ixesha elide, nto leyo eyenza ukuba ifaneleke kakhulu ekwakhiweni kweziseko zoomatshini kunye neebhedi.
Izinto eziphambili zebhedi yegranite ziquka i-feldspar, i-quartz, kunye ne-mica. I-Feldspar liqela leeminerali ezenza amatye ezifumaneka rhoqo kwi-granite. Yeyona minerali ininzi kwi-granite, kwaye ubukho bayo edwaleni buyenza ibe noburhabaxa. I-Quartz yenye iminerali efumaneka kakhulu kwi-granite. Yiminerali eqinileyo nebuthathaka enokumelana namaqondo obushushu aphezulu, nto leyo eyenza ukuba ifaneleke ukusetyenziswa kwiindawo ezichanekileyo. Kwelinye icala, i-Mica yiminerali ethambileyo eyenza iiflekhi ezincinci neziguquguqukayo. Ubukho bayo kwi-granite bunceda ukubonelela ngozinzo kwaye buthintele ukuqhekeka.
Ukusetyenziswa kwebhedi yegranite kwizixhobo ze-semiconductor kuneenzuzo ezininzi. Okokuqala, ibonelela ngomphezulu ozinzileyo nothe tyaba kakhulu ukuze i-wafer ye-semiconductor iphumle kuwo. Oku, kuvumela iinkqubo zokuvelisa ezichanekileyo ngakumbi kuba naluphi na uphambuko oluncinci okanye utshintsho kumphezulu webhedi lunokubangela iimpazamo okanye ukungasebenzi kakuhle kwisixhobo se-semiconductor. Ubunzima bebhedi yegranite bukwathetha ukuba akunakwenzeka ukuba yonakale okanye iguquguquke ngokuhamba kwexesha, okuqinisekisa uzinzo oluqhubekayo lwezixhobo.
Enye inzuzo yokusebenzisa ibhedi yegranite kwizixhobo ze-semiconductor kukuba ine-coefficient yokwandisa ubushushu ephantsi. Oku kuthetha ukuba inokumelana notshintsho kubushushu ngaphandle kokuchaphazela ukusebenza kwesixhobo se-semiconductor. Ngenxa yoko, abavelisi be-semiconductor banokuqhuba iinkqubo ezifuna amaqondo obushushu aphezulu ngaphandle kokukhathazeka ngokwandiswa kobushushu okanye ukucutheka. Ngaphezu koko, ithintela ukukhula kwe-thermal gradients, enokuba yingozi ekusebenzeni kwezixhobo.
Isiphelo
Ukuqukumbela, ukusetyenziswa kwebhedi yegranite kwizixhobo ze-semiconductor kuye kwaguqula ishishini, nto leyo ekhokelele ekuphuhlisweni kwezixhobo ezisebenzayo nezichanekileyo. Izinto eziphambili zebhedi yegranite, kuquka i-feldspar, i-quartz, kunye ne-mica, ziqinisekisa ukuba ibhedi iqinile, izinzile, kwaye inomlinganiselo wokwandisa ubushushu ophantsi. Oku kuyenza ifaneleke kakhulu ekwakhiweni koomatshini abafuna ukuchaneka okuphezulu, njengabo basetyenziswa ekuveliseni izixhobo ze-semiconductor. Ukusetyenziswa kwebhedi yegranite kuya kuqhubeka nokuba yinxalenye ebalulekileyo kangangeminyaka emininzi ezayo, njengoko abavelisi bezama ukuphuhlisa izixhobo ze-semiconductor ezintsonkothileyo ngakumbi.
