Then the pull-off force and stick-slip resistant performance of the smooth silicon surface and the modified silicon surface were investigated by a home-made micro-tribotester in the situations of micro load and various relative humidity levels.

Micro stick-slip and stiction failure are familiar phenomena in microelectromechanical systems due to the dominant role of various surface forces including electrostatic force, van der Waals force and capillary force.
