Umbhede wegranite ungenye yezinto ezivame kakhulu ezisetshenziswa ekwakhiweni kwemishini ye-semiconductor enembile kakhulu. Liyidwala elakhiwa ukuqina kwe-magma okuhamba kancane ngaphakathi koqweqwe lomhlaba. Isici esibalulekile segranite ukuthi iyinto eqinile, eqinile, futhi eqinile, okwenza ifaneleke ukusetshenziswa ekwakhiweni kwezisekelo zomshini nemibhede.
Izingxenye eziyinhloko zombhede we-granite zifaka phakathi i-feldspar, i-quartz, kanye ne-mica. I-Feldspar iyiqembu lamaminerali akha amadwala avame ukutholakala ku-granite. I-mineral eningi kakhulu ku-granite, futhi ukuba khona kwayo edwaleni kuyinika ukuthungwa okuqinile. I-Quartz ingenye iminerali etholakala kakhulu ku-granite. I-minerali eqinile futhi ebuthakathaka engamelana namazinga okushisa aphezulu, okwenza ifaneleke ukusetshenziswa ekusetshenzisweni okunembe kakhulu. I-Mica, ngakolunye uhlangothi, iyiminerali ethambile eyakha ama-flakes amancane futhi aguquguqukayo. Ukuba khona kwayo ku-granite kusiza ukunikeza ukuzinza futhi kuvimbele ukuqhekeka.
Ukusetshenziswa kombhede wegranite kumadivayisi e-semiconductor kunezinzuzo eziningana. Okokuqala, kunikeza indawo ezinzile kakhulu futhi eyisicaba ukuze i-wafer ye-semiconductor ihlale kuyo. Lokhu, kuvumela izinqubo zokukhiqiza ezinembile kakhulu njengoba noma yikuphi ukuphambuka okuncane noma ukushintshashintsha ebusweni bombhede kungaholela emaphutheni noma ekungalungini kahle kudivayisi ye-semiconductor. Ukuqina kombhede wegranite kusho nokuthi cishe ngeke wonakale noma ukhubazeke ngokuhamba kwesikhathi, okuqinisekisa ukuzinza okuqhubekayo kwemishini.
Enye inzuzo yokusebenzisa umbhede we-granite kumadivayisi e-semiconductor ukuthi une-coefficient yokwandisa ukushisa ephansi. Lokhu kusho ukuthi ingamelana nezinguquko ekushiseni ngaphandle kokuthinta ukusebenza kwedivayisi ye-semiconductor. Ngakho-ke, abakhiqizi be-semiconductor bangenza izinqubo ezidinga amazinga okushisa aphezulu ngaphandle kokukhathazeka ngokukhula kokushisa noma ukufinyela. Ngaphezu kwalokho, kuvimbela ukukhula kwama-gradient okushisa, okungaba yingozi ekusebenzeni kwemishini.
Isiphetho
Ekuphetheni, ukusetshenziswa kombhede wegranite kumadivayisi e-semiconductor kushintshe imboni, okuholele ekuthuthukisweni kwemishini esebenza kahle futhi enembile. Izingxenye eziyinhloko zombhede wegranite, okuhlanganisa i-feldspar, i-quartz, ne-mica, ziqinisekisa ukuthi umbhede uqinile, uzinzile, futhi une-coefficient yokukhulisa ukushisa ephansi. Lokhu kuyenza ifaneleke kakhulu ekwakhiweni kwemishini edinga ukunemba okuphezulu, njengaleyo esetshenziswa ekukhiqizweni kwamadivayisi e-semiconductor. Ukusetshenziswa kombhede wegranite kuzoqhubeka nokuba yingxenye ebalulekile amashumi eminyaka ezayo, njengoba abakhiqizi belwela ukuthuthukisa amadivayisi e-semiconductor ayinkimbinkimbi nakakhulu.
