ABSTRACT:
A microelectromechanical system switch may be formed with a protrusion defined on the substrate which makes contact with a deflectable member arranged over the substrate. The deflectable member may, for example, be a cantilevered arm or a deflectable beam. The protrusion may be formed in the substrate in one embodiment using field oxide techniques.
