ukuqonda inqubo yokuhlanza kanye nokungcola kwe-semiconductor wafer

Uma isidoda sifikaizindaba zebhizinisi, ukuqonda ubuciko bokwenziwa kwe-semiconductor kuyadingeka. I-wafer ye-semiconductor iyisici esibalulekile kulo mkhakha, kodwa ivame ukubhekana nokungcola okubangelwa ukungcola okuhlukahlukene. Lokhu kungcola, okuhlanganisa i-athomu, izinto eziphilayo, i-ion ye-metallic element, kanye ne-oxide, kungathinta inqubo yokwenziwa.

Izinhlayiyanjengokungcola kwe-polymer kanye nokugqwala, ukuthembela emandleni aphakathi kwama-molecule ukuze kufakwe ebusweni be-wafer, kuthinta i-photolithography yedivayisi.ukungcola okungokwemvelonjengamafutha esikhumba se-homo kanye nefilimu yamafutha omshini efomini ye-wafer, kuvimbela ukuhlanza.ama-ion ezinto zensimbinjengensimbi ne-aluminium zivame ukususwa ngokwakhiwa kwe-ion complex ye-metallic element.Ama-Oxidekuphazamisa inqubo yokwenziwa futhi ngokuvamile kususwa ngokucwilisa ku-hydrofluoric acid encibilikisiwe.

izindlela zamakhemikhaliNgokuvamile zisetshenziselwa ukuhlanza nokuhluza i-wafer ye-semiconductor. Indlela yokuhlanza amakhemikhali omswakama njengokucwiliswa kwesisombululo kanye nokuhlafuna ngomshini iyathandwa. Indlela yokuhlanza ye-supersonic kanye ne-megasonic inikeza izindlela eziphumelelayo zokususa ukungcola. Ukuhlanza amakhemikhali okomile, kufaka phakathi ubuchwepheshe be-plasma kanye ne-gas phase, nakho kudlala indima ezinqubweni zokuhlanza i-wafer ye-semiconductor.
