Chemical etching

By Institut Catala de Nanociencia i Nanotecnologia (ICN2)

Wet Etching is an etching process that utilizes liquid chemicals or etchants to remove materials from the sample. Wet etching is generally isotropic, i.e., it proceeds in all directions at the same rate. An etching process that is not isotropic is referred to as 'anisotropic.' An etching process that proceeds in only one direction (e.g., vertical only) is said to be 'completely anisotropic'. Process: Chemical etching Type: Wet etching Chemistry used: Acids (HCl, HF) Instrument: Fumehood
