摘要:
A microelectromechanical system (MEMS) device that reduces or eliminates stiction includes a substrate and a movable element at least partially suspended above the substrate and having at least one degree of freedom. A protrusion extends from the substrate and is configured to contact the movable element when the moving element moves in the at least one degree of freedom. The protrusion comprises a surface having a low surface energy relative a silicon oxide surface. The protrusion may be coupled to a voltage potential node to avoid or counteract electrostatic forces.
