Lapho isidoda ukuzeizindaba zebhizinisi, ukuqonda ukunethezeka kokwenziwa kwe-semiconductor kuyisidingo. I-semiconductor wafer iyingxenye ebalulekile kulo mkhakha, kodwa ngokuvamile ibhekana nokungcoliswa okuvela ekungcoleni okuhlukahlukene. Lokhu kungcola, okuhlanganisa i-athomu, i-organic matter, i-ion ye-metallic element, ne-oxide, kungaba nomthelela enqubweni yokwenziwa.
Izinhlayiyanjenge-polymer kanye ne-etching ukungcola trust kumandla we-intermolecular ukukhangisa endaweni ye-wafer, kuthinta i-photolithography yedivayisi.ukungcola okuphilayonjengamafutha esikhumba se-homo kanye nefilimu yamafutha omshini ku-wafer, kuvimbela ukuhlanzwa.metallic element ionsnjengensimbi ne-aluminium kuvame ukususwa ngokwakhiwa kwe-metallic element ion complex.Ama-oxidezithiya inqubo yokwenziwa futhi ngokuvamile zisuswa ngokucwiliswa ku-dilute hydrofluoric acid.
izindlela zamakhemikhalingokuvamile zisetshenziselwa ukuhlanza nokujeqeza isicwecwana se-semiconductor. Indlela yokuhlanza amakhemikhali omswakama njengokucwiliswa kwesixazululo kanye nokukhuhla ngomshini kuyasebenza. indlela yokuhlanza ye-supersonic ne-megasonic inikeza izindlela eziphumelelayo zokususa ukungcola. ukuhlanzwa kwamakhemikhali okomile, kufaka phakathi ubuchwepheshe besigaba se-plasma negesi, nakho kudlala umsebenzi ezinqubweni zokuhlanza i-wafer ye-semiconductor.
