Xa isemadodeniiindaba zoshishino, ukuqonda ubunzulu bokwenziwa kwe-semiconductor kuyimfuneko. I-semiconductor wafer yinxalenye ebalulekileyo kolu shishino, kodwa bahlala bejongana nokosulelwa bubumdaka obuhlukeneyo. Ezi zingcolisi, ziquka i-athomu, i-organic matter, i-metallic element ion, kunye ne-oxide, inokuchaphazela inkqubo yokwenziwa.
Amacandeloezinje ngepolymer kunye ne-etching ubumdaka trust kumandla e-intermolecular ukuthengisa kumphezulu we-wafer, kuchaphazela i-photolithography yesixhobo.ukungcola okuphilayonjenge-homo skin oil kunye ne-oil form form movie kwi-wafer, kuthintela ukucocwa.metallic element ionsnjengentsimbi kunye ne-aluminiyam zihlala zisuswa ngokuyilwa kwe-ion complex element yesinyithi.Iioksidizithintela inkqubo yokwenziwa kwaye zisuswa ngokufunxa kwi-dilute hydrofluoric acid.
iindlela zamachizaziqhele ukusetyenziselwa ukucoca kunye ne-jerk semiconductor wafer. ubuchule bokufuma bokucoca iikhemikhali ezifana nokuntywiliselwa kwesisombululo kunye nokukhuhla ngoomatshini kuxhaphakile. indlela yokucoca i-supersonic kunye ne-megasonic inikezela ngeendlela ezifanelekileyo zokususa ukungcola. ukucocwa kweekhemikhali ezomileyo, kubandakanya i-plasma kunye ne-gas phase technology, nayo idlala umsebenzi kwiinkqubo zokucoca i-wafer semiconductor.
