KOH etching results in uniform and bright etched surface in a near saturated solution at 80◦C. Etching rate of the (1 0 0) silicon plane is 1.4 µm/min at 80◦C in 50 wt. % KOH solution [1]. However, the condition of etching and non-uniformity of the etching rate becomes considerably worse above 80◦C. The G-P zones have no well defined crystal structure of their own and they contain a high concentration of, in this case, beryllium atoms. The formation of G-P zones usually coincides with a change in properties. In the case of beryllium copper alloys, the property change is an increase in strength.
