Just put it in the etchant:)))))

Geometry of an etching pit in a orientation-dependent etching of Si
depends on 2 things only:

1. Crystal orientation of Si-wafer (e.g. 100 or 111)
2. Solution of the etchsnt

Hi,

  I am  trying to produce v-groove on Si using KOH. Could any one please
tell me how to place the Si wafer (either verical or horizontal i.e just
dropping the wafer in the solution) in the KOH solution and also could
you please give me particular reasons for choosing the one. I would
really appreciate if any one could reply to this mail as soon as
possible.

Thanks,
