<p>A microelectromechanical (MEM) device (20) includes a substrate (22) and a flexible cantilever beam (28). The substrate (22) has positioned thereon a first interconnection line (24a) separated by a first gap (26a) and a second interconnection line (24b) separated by a second gap (26b) parallel to the first interconnection line (24a). The substrate (22) also has positioned thereon a first and second primary control electrode (38a, 38b) wherein one of the first and second primary control electrodes (38a, 38b) is positioned on one side of one of the first and second interconnection lines (24a, 24b) and the other one is positioned on the other side of the other first and second interconnection lines (24a, 24b). The flexible cantilever beam (28) has a top surface and a bottom surface and a beam width slightly larger than the gap widths at the gaps (26a, 26b). A flexible anchor (32) is secured to the bottom surface of the beam (28) at a center of the beam (28) and attached to a center of the substrate (22) so as to position the beam (28) orthogonally to the first and second interconnection lines (24a, 24b). Secondary control electrodes (40a, 40b) are secured to the bottom surface of the beam (28) and positioned opposite the primary control electrodes (38a, 38b). First and second contact pads (30a, 30b) are secured to the bottom surface of the beam (28) and positioned opposite the first and second interconnection lines (24a, 24b). <IMAGE></p> |
