[mems-talk] Silicon resistivity for comb-actuation

[bob hou]

I think it is better to observe the movement by Wyko/Zyko, which apply the interference principle and is sensitive to see the tiny movement.

Hello all,

I am trying to actuate a comb-actuator. However, I was not able to see 
any movement under Karl Suss probe station.

The resistivity of my SOI wafer is 1-30 Ohmcm. Dopant tytpe is P/Boron.

The wafer is from ULTRASIL.

I am applying a static voltage differenece, i am not interested about 
dynamic voltages for now. Is it a problem to use 1-30 Ohmcm 
resistivity Silicon.

Thanks in advance,
