摘要： A micro-switching device includes a base substrate and a cantilever fixed to the base substrate via a spacer or anchor portion. The cantilever has an inner surface facing the substrate and an outer surface opposite to the inner surface. A conductive strip is formed on the outer surface of the cantilever. The switching device also includes a pair of stationary electrodes fixed to the base substrate. Each of the electrodes includes a downward contacting part spaced from the conductive strip on the cantilever. As the cantilever bends upward, the conductive strip is brought into contact with the contacting parts of the respective stationary electrodes.

摘要： A capacitor manufacturing method provides variable capacitors whose capacitances remain stable under the influence of temperature change. Such a variable capacitor includes a fixed electrode, a movable electrode film facing the fixed electrode, and an anchor portion that provides partial connection between the fixed electrode and the movable electrode film. For making this variable capacitor, a first electrode is formed to serve as the fixed electrode. Then, an anchor portion is formed on the fixed electrode, and a sacrifice film is formed to cover the fixed electrode but partially expose the anchor portion. A second electrode is formed on the sacrifice film to serve as the movable electrode film, bonded to the anchor portion. Finally, the sacrifice film is removed.

摘要： In a method for drive controlling a micro machine device including two electrodes opposing each other and a dielectric layer sandwiched therebetween, a control voltage in a rectangular waveform in which positive and negative polarities are alternately inverted is applied between the two electrodes. A current passing through the micro machine device due to the application of the control voltage are detected with respect to positive and negative sides, and parameters related to a capacitance of the micro machine device are acquired with respect to the positive and negative sides on the basis of the detected current. The control voltage is controlled so that the parameters acquired with respect to the positive and negative sides accord with each other. Thus, variation of the capacitance between the positive side and the negative side can be suppressed in switching drive of a variable capacitance device.
