Chemical Etching - Metals and Semiconductors

Selective Chemical Etching

A list providing some general etch information. Specific etches of certain materials are given, along with information about what else should or should not be etched by the etchant. Some etch rates are provided.

Metal and Semiconductor Wet Etching

A comprehensive list of etchants for over 50 different metals, semiconductors and cleanroom materials. Some etch rates are given. The ratios are volume ratios unless other units are specified.

KOH Etching

Etch rates For silicon, silicon nitride, and silicon dioxide in varying concentrations and temperatures of KOH. Reference: J. Electrochem. Soc. Vol 137, 11, Nov 1990, 3612-3632.
