Abstract
Micro-cantilever structure is flexible and liable to be destroyed compared its volume with its area. Failure mode and effect analysis can be predicted at an early stage of the micro-beam design. Stiction is a main failure mode for cantilever in its manufacture process and operation. Under the load shock, if the contact length reached the limit length, the restoration energy in micro-cantilever couldn't resist the stiction energy, the micro-cantilever would stiction on the substrate. Pull-in was a main failure mode for electrostatic micro-cantilever. The pull-in voltage was obtained by mechanical and electrical couple analysis on the base of the FEM model.
