"Webb2) Wafers When etching into Silicon using KOH or TMAH, always use prime wafers. If you are doing a shallow etch, single sided polished is fine, but to go through a wafer or remove a large part of a wafer, double sided is needed to do the alignment. The reason why prime wafers are needed is that the ‘history’ of the wafer is critical " - Slurry wafer
