Ziyini izingxenye ze-granite zenqubo yokukhiqiza i-semiconductor?

I-granite iyinto evamile esetshenziswa ezimbonini ezahlukahlukene ngenxa yokuqina kwayo, amandla, kanye nekhono lokumelana nokuguguleka. Enye yezindlela zokusebenzisa i-granite isenqubo yokukhiqiza i-semiconductor lapho isetshenziswa khona njengesisekelo sokukhiqizwa kwama-microchip, amasekethe ahlanganisiwe, nezinye izingxenye ze-elekthronikhi.

Enye yezingxenye ezibalulekile zokukhiqiza i-semiconductor yi-photolithography, ehilela ukusetshenziswa kokukhanya ukudlulisa amaphethini ku-silicon wafer. Amapuleti e-granite asetshenziswa kule nqubo njengesisekelo lapho ifilimu encane esetshenziselwa ukudlulisa amaphethini imbozwa khona. I-granite ikhethwa kakhulu ku-photolithography ngenxa yokuba yisicaba kwayo kwemvelo, okuqinisekisa ukuthi ifilimu encane esetshenziswa ebusweni bayo ibushelelezi futhi iyafana. Ukusetshenziswa okubushelelezi nokulinganayo kwefilimu encane kubalulekile ekuqinisekiseni ukuthi amaphethini adalwe ku-wafer anembile futhi anembile.

I-granite isetshenziswa futhi ekwakhiweni kwamabhentshi okusebenzela nemishini yegumbi lokuhlanza. Ngesikhathi sokukhiqizwa kwama-semiconductors, ukuhlanzeka kubaluleke kakhulu, futhi noma yiziphi izinhlayiya ezincane noma uthuli kungalimaza izingxenye. Ngakho-ke, izinto ezisetshenziswa emakamelweni okuhlanza kudingeka zingachithi, zingabi yingozi, futhi kube lula ukuzihlanza. I-granite ihlangabezana nalezi zidingo, okwenza ibe yinto efanelekile yokukhiqiza amabhentshi okusebenzela neminye imishini ekamelweni lokuhlanza.

Okunye ukusetshenziswa kwe-granite ekukhiqizweni kwe-semiconductor kusekwakheni izinhlelo ze-vacuum. Uhlelo lwe-vacuum lubalulekile enqubweni yokukhiqiza njengoba lusetshenziselwa ukudala indawo enomfutho ophansi oqinisekisa ukuthi izingxenye ze-semiconductor ezikhiqizwayo zisezingeni eliphezulu. Amandla aphezulu kanye ne-coefficient ephansi yokwanda kokushisa kwe-granite kwenza kube yinto ethembekile yokwakha igumbi le-vacuum.

Ekuphetheni, i-granite iyinto ewusizo ekukhiqizweni kwe-semiconductor ngenxa yezakhiwo zayo eziyingqayizivele njengokuqina, amandla, kanye nokuqina kokushisa. Ukuthamba kanye nokuhlanzeka kwemvelo kwe-granite kuyenza ifanelekele i-photolithography, amabhentshi okusebenzela ahlanzekile, kanye nezinhlelo ze-vacuum. Ukusetshenziswa kwe-granite embonini ye-semiconductor kuwubufakazi bokuguquguquka kwayo kanye nokuzivumelanisa nezimo nezinhlelo ezahlukahlukene, okufakazela ukuthi akuyona nje into yokuhlobisa kodwa futhi iyingxenye ebalulekile ezinqubweni ezahlukahlukene zezimboni.
