Potassium Hydroxide (KOH) etching is a wet chemical etching process used to create cavities in silicon. Highly corrosive alkaline chemical compound (pH > 12) is used in conjunction with DI water and thermal regulation. The etch rate is depending on the concentration of the KOH solution and temperature. KOH is a strong, corrosive base and should be handled with extreme care.
