    摘要： A fixed voltage and a movable electrode are placed face to face with each other, and an insulating film is formed on the surface of the fixed electrode. The insulating film is made of a nitride film (SiN) as a main material, with oxide films (SiO2) being formed on the front and rear surfaces of the nitride film. Moreover, a plurality of protrusions are formed on an area facing the movable electrode of the upper face of the insulating film. The charge quantity in the insulating film is mainly determined by a film thickness of the oxide film, and the nitride film is used for maintaining a sufficient film thickness required for the voltage proof characteristic. Thereby, it is possible to suppress variations in operational voltage characteristics such as on-voltage and off-voltage in an electrostatic actuator so as to prevent phenomena in which the electrostatic actuator fails to turn on even when a rated voltage is applied to the electrostatic actuator and in which the electrostatic actuator fails to turn off even when the driving voltage is turned off.

    摘要翻译： 固定电压和可动电极彼此面对地放置，并且在固定电极的表面上形成绝缘膜。 绝缘膜由氮化物膜（SiN）作为主要材料制成，在氮化膜的正面和背面形成有氧化物膜（SiO 2/2）。 此外，在与绝缘膜的上表面的可动电极相对的区域上形成多个突起。 绝缘膜中的电荷量主要由氧化膜的膜厚确定，并且氮化膜用于保持耐电压特性所需的足够的膜厚度。 由此，可以抑制静电致动器中的导通电压和截止电压等工作电压特性的变化，从而防止静电致动器即使向静电致动器施加额定电压也不能接通的现象 并且即使当驱动电压关闭时静电致动器也不能关闭。

    摘要： An electrostatically actuated micro-mechanical switching device with movable elements formed in the bulk of a substrate for closing and releasing at least one Ohmic contact by a horizontal movement of the movable elements in a plane of the substrate. The switching device has a drive with comb-shaped electrodes including fixed driving electrodes and movable electrodes. A movable push rod is mechanically connected with the movable electrodes, extends through the electrodes, has a movable contact element at one side, and at least one restoring spring. A signal line has two parts interrupted by a gap. The micro-mechanical switching device is in shunt-configuration with low loss, high isolation in a wide frequency range, low switching time at low actuation voltage and sufficient reliability. The line impedance of the signal line and its variation is as small as possible. The switching device is in shunt-configuration for closing and releasing the Ohmic contact between a ground line and the signal line. The contact element has a movable contact beam extending at least partially opposite to the signal line and being electrically and mechanically connected to both parts of the signal line, respectively. The ground line is formed with a contact bar that leads through the gap of the signal line for forming the Ohmic contact between the contact beam and the ground line. A contact metallization is provided at least on top and on the side walls of the contact beam, of the signal line and of the ground line.
