The Large Etch Cell

The Large Etch CellOne of the most common applications of an electrochemical etching cell is the preparation of a Nanocrystalline Porous Silicon Layer on a single crystal Si wafer. Application note To perform an electrochemical process, a square conducting sample is placed on the cell base, using a piece of aluminum foil as a back contact. The setup is sealed by an O ring to prevent electrolyte leakage. The cell is filled with an electrolyte, and the wire electrode is
