Wet bench used for the etching of metals such as gold, chromium, aluminium, platinum, copper, nickel,...and metal based oxydes such as AZO or ITO. The etching is done manually by pouring the suited wet etch solution in a dish and dipping the metalized wafer in the solution until the desired metalic layer is removed. The wafer is then pre-rinsed in a second dish of DI water and then rinsed in a rinse bath. After rinsing, the wafer is dried with a nitrogen gun or spinned dry. Beware of corrosive chemicals on the bench before use.Make sure there is no residues before starting to work.In case of suspect liquid on the bench rinse with DI water and dry prior to use.
