For wet and dry etching, each type of material requires certain etchants to be used. Some of them have very high selectivity and remove only the desired layer; others affect many layers at a time. For example, silicon and polysilicon can be etched with a mixture of hydrofluoric acid HF and nitric acid HNO3, but HF etches silicon oxide as well.
Other etchants are used for specific purposes, such as doping etchants with a doping-dependent etch rate to make visible doping fronts and p-n junctions. Such etchants are used, for example, to make visible the contents of VTROM in modern smartcards [8]. More information about different etchants and etching technology can be found in the literature on failure analysis techniques.
