Hi Hima,

I have used 1:1 (45%KOH:DI water) at 80 degrees celcius and have gotten an etch rate of ~1um/min for Silicon (111). In my experience you can take the samples out from the solution and measure using a contact profiler and put it back in with minimum stress induced.

Norliana Yusof

You can use DOE method for process optimization,such as RSM or taguchi method

Zohreh Shakeri

I suggest using this genetic algorithm for optimization.
