Hi all:

I need to wet-etch a Si layer which thickness is around 50 nm. In order to
do this, I plan to use the 25% TMAH at room temperature. If anybody has any
experience with 25% TMAH at room temperature, may I share your experience,
such as wet etching procedure and etching rate.

Thank you.
Kind Regards,
Donkoun Lee
