Izici
1. Izinga eliphakeme lokuvikelwa kwemvelo: ukufakwa okukhethiwe kungafinyelelwa ngaphandle kokusebenzisa izisekelo zemvelo ezifana ne-TMAH;
2. Izindleko eziphansi zokukhiqiza: Uma kuqhathaniswa nokwelashwa okuvamile kusetshenziswa i-hydrofluoric acid/nitric acid emakethe, izindleko zokukhiqiza zehla kakhulu;
3. Ukusebenza kahle kwe-etching ephezulu: Uma kuqhathaniswa nenqubo yebhethri ye-Perc, ukusebenza kahle kokuguqulwa kukhuphuke ngaphezu kuka-1.2%;

Lezi zakhiwo zingahluka kuye ngokuthi i-crystal wafer eyodwa, inqubo, inqwaba, nosayizi.
Izinhlelo zokusebenza
1, Lo mkhiqizo uhloselwe ukususa i-amorphous silicon enamathela kumaseli e-topcon;
2, Ifanele amaseli e-monocrystalline we-210, 186, 166, kanye ne-158 imininingwane.
