Wet-Chemical Etching and Cleaning of Silicon
Table 2 relates silicon orientation-dependent etch rates of KOH to percent composition, temperature, and orientation. Table 2 is taken directly from . As with all wet-chemical etching solutions, the dissolution rate is a strong function of temperature.
Etchmaster Store - Dobbins Enterprises LLC: Abrasives
The really significant advantage to carbide or oxide is the fact that they etch glass about twice as fast as the other abrasives. So, in addition to savings on materials costs, the oxide and carbide provide an almost 50% saving in labor costs as well.
KOH Etching - Welcome to the BYU Cleanroom - the …
If silicon nitride is being used as a mask for silicon etching, potential etching of the silicon nitride need not be taken into consideration. KOH etching of silicon dioxide is observable. The etch rates are considerably slower (1-2 orders of magnitude) than that of silicon but should be considered when deep etching is being done.
