WebMoreover, chromium is a good hard masking material for dry etching, as it is relatively sputter resistant7 and has high selectivity in fluorine and bromine chemistries. WebMar 1, 2024 · Some mask materials include gold, titanium, chromium, oxides, and nitrides, depending on which material is subjected to etching (for example, metal or silicon as the etching piece). Generally speaking, in wet etching, engineers use substances such as hydrofluoric acid, nitric acids, phosphoric acids, and hydrochloric acids. WebDuring the dry etching process, the roughness of the polished side will increase as XeF 2 gas starts to etch the surface. In this case, starting the etching process either on the polished or un-polished side will not impact the final roughness value of MNs. ...
