Kana urume kutinhau dzebhizimisi, kunzwisisa kukwenenzverwa kwekugadzira semiconductor chinhu chakakosha. semiconductor wafer chinhu chakakosha muindastiri iyi, asi kazhinji vanotarisana nekusvibiswa kubva mukusachena kwakasiyana. Izvi zvinosvibisa, zvinosanganisira atomu, organic matter, metallic element ion, uye oxide, zvinogona kukanganisa maitiro ekugadzira.
Zvimedusenge polymer uye etching kusachena kuvimba pane intermolecular simba kuti adsorb pamusoro pewafer pamusoro, inokanganisa mudziyo photolithography.organic tsvinasenge homo ganda mafuta uye muchina mafuta fomu bhaisikopo pane wafer, kutadzisa kuchenesa.metallic element ionssesimbi nealuminium zvinowanzo bviswa kuburikidza nekugadzirwa kwesimbi element ion complex.Oxideskukanganisa maitiro ekugadzira uye anowanzo kubviswa nekunyorova mu dilute hydrofluoric acid.
makemikari nziraanowanzo kushandiswa kuchenesa uye jerk semiconductor wafer. mwando kemikari yekuchenesa nzira senge mhinduro submergence uye mechanical scrub irikuripo. supersonic uye megasonic yekuchenesa nzira inopa nzira dzakasimba dzekubvisa kusachena. yakaoma makemikari kuchenesa, inosanganisira plasma uye gasi chikamu tekinoroji, zvakare tamba basa mune semiconductor wafer yekuchenesa maitiro.
