Yiziphi izingxenye ze-granite zenqubo yokukhiqiza i-semiconductor?

I-Granite iyinto evamile esetshenziswa ezimbonini ezihlukahlukene ngenxa yokuqina kwayo, amandla, namandla okumelana nokuguga. Okunye kwezicelo zegwadle kusenqubweni yokukhiqiza ye-semiconductor lapho isetshenziswa njenge-substrate yokukhiqiza ama-microchips, amasekethe ahlanganisiwe, nezinye izakhi zikagesi.

Enye yezingxenye ezibalulekile zokwenziwa kwe-semiconductor i-photolithography, ebandakanya ukusetshenziswa kokukhanya ukudlulisa amaphethini ku-silicon wafer. Amapuleti e-granite asetshenziswa kule nqubo njengesisekelo lapho ifilimu encane esetshenziselwa ukudlulisa amaphethini iboshwe. I-Granite ikhethwa ku-photolithography ngenxa yemvelo yayo yemvelo, okuqinisekisa ukuthi ifilimu encane esetshenziswe ebusweni bayo ibushelelezi futhi ifana. Ukusetshenziswa okubushelelezi nokufanayo kwefilimu elincanyana kubalulekile ekuqinisekiseni ukuthi amaphethini adalwe ku-wafer anembile futhi anembe.

I-Granite isetshenziswa futhi ekwenzeni amabhentshi okusebenzela ahlanzekile nemishini. Ngesikhathi sokukhiqizwa kwama-semiconductors, ukuhlanzeka kubaluleke kakhulu, futhi noma yiziphi izinhlayiya ezincane noma uthuli lungalimaza izingxenye. Ngakho-ke, izinto ezisetshenziswa ezindlini zokuhlanza kudingeka zingachithi, zingasasebenzi, futhi kube lula ukuzihlanza. I-Granite ihlangabezana nalezi zidingo, iyenze ibe yinto ephelele yokukhiqiza amabhentshi okusebenza nezinye izinto zokusebenza endlini yokuhlanza.

Okunye ukusetshenziswa kwe-granite ekukhiqizeni i-semiconductor kusekwakheni amasistimu we-vacuum. Uhlelo lwe-vacuum lubalulekile enqubweni yokukhiqiza njengoba lusetshenziselwa ukwakha indawo enengcindezi ephansi eqinisekisa ukuthi izingxenye ze-semiconductor ezikhiqizwayo zisezingeni eliphezulu. Amandla aphezulu kanye ne-coefficient ephansi yokwanda okushisayo kwe-granite kwenza kube yinto enokwethenjelwa yokwakha igumbi le-vacuum.

Sengiphetha, i-granite iyinto ebalulekile ekwenziweni kwe-semiconductor ngenxa yezakhiwo zayo ezihlukile njengokuqina, amandla, nokuzinza kwe-thermal. Ukucaba nokuhlanzeka kwemvelo kwegwadle kuyenza ifanelekele i-photolithography, amabhentshi okusebenzela egumbi elihlanzekile, nezinhlelo ze-vacuum. Ukusetshenziswa kwe-granite embonini ye-semiconductor kuwubufakazi bokusebenza kwayo okuhlukahlukene kanye nokuvumelana nezimo ezisetshenziswayo ezihlukahlukene, okufakazela ukuthi akuyona nje into yokuhlobisa kodwa futhi iyingxenye ebalulekile ezinqubweni ezihlukahlukene zezimboni.
