Dear Changhong Ke,

I would recommend measuring the contact angle. The surface properties of
the Si substrate
are important and can vary depending on your process. The water may also
have some trace contaminants that may effect the results.  In addition, the
contact angle is usually broken down
into advancing/receding.
I believe that measuring the contact angle with respect to the process you
have ( realistic samples of the substrate and fluids) in mind will provide
you a more realistic value.
