Yibuni ubuchwepheshe bokucubungula izingxenye zamatshe ama-sconite emishini ye-semiconductor?

Ngokukhula kobuchwepheshe, ukusetshenziswa kwezingxenye ze-granite emishini ye-semiconductor sekudumile. I-Granite iyisinqumo esidumile sokusebenzisa ubuchwepheshe bokucubungula imishini yemishini ye-semiconductor ngenxa yezinzuzo zayo eziningi. IGranite ingenye yezinto ezinzima kakhulu futhi ezihlala isikhathi eside kakhulu ezitholakalayo ezenza ilungele ukusetshenziswa embonini yokukhiqiza i-semiconductor. Kungumqhubi omuhle kakhulu we-thermal futhi unesihlanganisi esiphansi kakhulu sokwandisa okushisayo okwenza kube kulungele ukusetshenziswa ezinhlelweni zokushisa eziphezulu.

Ubuchwepheshe bokucubungula izingxenye ze-granite kumishini ye-semiconductor ibandakanya izindlela ezahlukahlukene nezinqubo. Izinyathelo ezibalulekile zipholishelwa, ukugcwala, nokuhlanza indawo egreni. Uhlobo lobuchwepheshe bokucubungula obusetshenzisiwe luzoncika kuhlelo lokusebenza nohlobo lwe-granite esetshenziswa.

Polishing isici esibucayi sokucubungula izingxenye zamatshe kumishini ye-semiconductor. Polishing ingaphezulu le-granite ngezinga eliphakeme lobushelelezi lisiza ekuqinisekiseni ukuthi i-wafer ayilimalanga ngesikhathi sokulungiswa. Lokhu kunciphisa amathuba okungcoliswa yizinhlayiya noma izinhlayiya ebusweni be-wafer. I-Polishing ingatholwa ngezindlela ezahlukahlukene ezinjengokupolaniswa kwemishini, ukuphonlisa kwamakhemikhali, kanye ne-electrochemical polishing, phakathi kwabanye.

I-Etching ingesinye isici esiyisisekelo sokucubungula izingxenye ze-granite kumishini ye-semiconductor. I-Etching isetshenziselwa ukudala amaphethini afiselekayo ebusweni bengxenye ye-granite. Amaphethini asetshenziswa ekwenzeni kanye nokucutshungulwa kwama-semiconductor weafers. Kunezindlela eziningana zokwenza i-etching, kufaka phakathi i-plasma etching, i-wet chemical etching, kanye namakhemikhali owomile wamakhemikhali, phakathi kwabanye. Uhlobo lwenqubo ye-etching esetshenzisiwe kuzoncika kokuqukethwe kanye nephethini efiselekayo.

Ukuhlanza indawo egremini nakho kuyabucayi. Inqubo yokuhlanza iyadingeka ukususa noma yikuphi ukungcola kusuka ebusweni, njengezinhlayiya nokunye ukungcola okungaphazamisa inqubo yokukhiqiza i-semiconductor. Ukuhlanza kungenziwa kusetshenziswa izindlela ezahlukahlukene njengokuhlanza kwe-ultrasonic, ukuhlanza amakhemikhali, noma ukuhlanzwa kwe-plasma, phakathi kwabanye.

Ekuphetheni, ubuchwepheshe bokucubungula izingxenye ze-granite emishini ye-semiconductor budlala indima ebalulekile enqubeni yokukhiqiza i-semiconductor. Ukusetshenziswa kwezingxenye ze-granite kusiza ukuthuthukisa ikhwalithi nokwethenjwa komkhiqizo wokugcina. Ubuchwepheshe bokucubungula bubandakanya ukucwaswa, ukugcoba, nokuhlanza indawo egreni. Kunezindlela ezahlukahlukene ezitholakalayo zesinyathelo ngasinye, kanye nohlobo lobuchwepheshe obusetshenzisiwe obusetshenzisiwe kuzoncika kokuqukethwe kanye nephethini efiselekayo. Ngokusebenzisa ubuchwepheshe bokucubungula abafanele, inqubo yokukhiqiza i-semiconductor ingenziwa isebenze kakhudlwana, ithembekile, futhi ibiza kakhulu.
