Hello Sanghoon,

I am also very interested in this phenomenon, and would appreciate hearing from
you when you find further information on this topic. In the meantime, here are a
few references to get you started:

"Parasitic charging of dielectric surfaces in capacitive microelectromechanical
systems (MEMS)"
Sensors and Actuators A (Physical)
v. A71,  p. 74, 1998

Measurements and Simulations"

Best wishes in all your research!
